Risk Management Associated With Foreign Currencies

Executive summary Risk management associated with foreign currencies has always been an issue and a challenging task for multinational companies. A firm s economic exposure to the exchange rate is the impact on net cash flow caused by the effect incurred in the exchange rate. Recently many financial instruments are being used by these firms to avoid the financial loss that can be the outcome of risky transactions. This paper aims to present a specific strategy using currency options to reduce foreign exchange risk in order to better manage it. The research results highlight the implications of the movement in exchange rate in the context of the transaction process and present a financial instrument to effectively manage this risk. More†¦show more content†¦Changes in the valuation of currencies create a form of risk widely known as currency risk. These changes can result in unpredictable gains or losses when the profits or dividends from an investment are converted from the foreign currency into domestic currency. To offset any currency-related gains or losses Firms use hedges and especially derivatives for an increased flexibility. Derivatives are both used for hedging against an undesired event and speculation for higher profit. This paper considers risk management for multinational companies, focusing on exchange rate risk management using currency options. It takes analysis from past work of previous authors on risk management and the use of currency options in an international market. The purpose of this paper is to explain and show possible different scenarios than can occur when trading in an international market by conducting a detailed research of the exchange risk management process at a single multinational company.

Aircraft Trajectory Prediction Free Essays

Literature Review Aircraft Trajectory Prediction By Cameron Sheridan I. Abstract The purpose of this review is to identify and analyse work that is currently being done on aircraft trajectory prediction (ATP); particularly the approach of modern day researchers to the problematic issue of the growingly clustered airspace. The benefits of this review include the exploration of several sub-topics of the literature. We will write a custom essay sample on Aircraft Trajectory Prediction or any similar topic only for you Order Now Through examining the current methods towards trajectory modelling validation and the techniques that are now employed to neutralise error sources, it was found that with the modern-day approaches an algorithm and its trajectory prediction (TP) can be assessed and consequently improved upon. A number of systems pertinent to conflict are discussed and results are presented which illustrate and compare the effectiveness of heading and altitudinal resolution manoeuvres. Additionally, a number of recent developments and innovations in the field pertinent to the technologies and techniques used are discussed, thus illustrating a clear indication of research still moving forward in this field. II. Introduction An ATP is a ‘mapping of points over a time interval [a,b] to the space R? ’ (Tastambekova et al. 2010, p. 2). Although this is correct in many senses, this explanation fails to acknowledge the intricacy and designed purpose. More accurately, a TP module has the capacity to calculate the future flight path of an aircraft given that it has been supplied with the required data, i. . the flight intent, an aircraft performance model, and finally, an estimation of the future atmospheric/environmental conditions (Swierstra and Green 2004). An aircraft trajectory is a future path of an aircraft that can be represented visually in three forms: 2D, 3D and 4D (x, y, altitude and time) with 4D the more frequently used nowadays by air traffic con trol (ATC) and air traffic management (ATM) due to its far more realistic representation and ease of interpretation (Vivona et al. 2010; Poretta et al. 010; Paglione and Oaks 2009). The significance of ATP is certainly appreciated. There is support for the importance of TP and the role it plays in advanced ATM operations, especially with a growingly clustered airspace in the next decade (Lee et al. 2010; Porretta et al. 2010 and Denery et al. 2011). The most crucial function of a TP however, as viewed by Lymperopoulos and Lygeros (2010), is to supply advice to ATC. Consequently, they can then make well-informed executive judgments to ensure the safety and effectiveness of our airspace. The purpose of this study is to inform what is happening in this field through examination of both the developments within ATP and the current problems facing researchers: namely, the significant increase in air-traffic by 2025. This will be done through exploring recent literature in this field that pertains to: conflict detection and resolution; the technologies and techniques involved; and, the error sources that are involved with a prediction and their subsequent effect on the uncertainty of a prediction. III. Modelling Validation and Uncertainties Efficiency and accuracy are two central points of this literature, which alone could be considered as the determining factors of a respectable TP model; thus, sufficient research is required to improve both, without the sacrifice of one. How does one validate the performance of an algorithm and whether its TP is ‘accurate’? The common answer it seems (Anonymous 2010 and Paglione and Oaks 2007, pp. 2) is through the degree of conformity between the measured or predicted data and the true data of an aircraft at a given time. A. Uncertainties Figure 1: Paglione and Oaks (2009) Figure 1: Paglione and Oaks (2009) Uncertainties are perhaps the biggest hurdle in further advancements in this field. Obviously, as the prediction increases in time, the uncertainties of the flight begin to take effect – up to a point where the trajectory becomes almost impossible to predict accurately with any degree of assurance. The consequential effect of uncertainties in a prediction may result in: two or more aircrafts losing separation; an aircraft not arriving to schedule; or even, the inability to detect flaws in either the ATP algorithm or the aircraft itself, to name a few. Therefore, there is a need to lessen the ffect of these lingering burdens. In reality this is quite difficult, and as such, requires particular attention of the algorithms used by an aircraft to validate its performance. B. Modelling Validation Performance validation verifies that a TP model performs correctly, and determines the degree of accuracy of a model’s representation compared to the real system (Vivona et al. 2010 and Garcia et al. 2009). There are further ways to validate predicted data; such methods include those shown by Paglione and Oaks (2007) who looked at the associated accuracy metrics; Poretta et al. 2008) who evaluated a 4D TP model for civil aircraft; and finally, the Plan, Do, Study, Act (PDSA) evaluation process of a TP (see figure 1). This practice and its application have been shown by Paglione and Oaks (2009). Inspired by the relationship of trajectory predictors to higher level applications, the authors stressed the need for improving modelling procedures through an iterative process consisting of four stages. Fredrick et al. (2009) were able to analyse ways to validate a program with their test and evaluation process. Particular focus was on a metrics approach which offers measures on the performance of an aircraft. This method may provide greater effectiveness in programs and is proclaimed to play a â€Å"critical role as a continuum of supporting activities for the TP programs† [Fredrick et al. (2009), pp. 9]. Vivona et al. (2010) also proposed a new methodology in her work which is designed for a similar purpose. The techniques used are titled ‘white box testing’ and ‘test bench testing’. The former involves knowledge of the internal processes that occur within a TP model, and through this information there will be a sequence of tests which accumulate together to validate the entire TP. The latter test is slightly different in that, as opposed to analysing current state data, it requires entering input data into an algorithm’s interface and then assessing the data that was produced as a result. Both are expected to become more commonly used in the approaching years. C. Error Sources and Corrective Measures Jackson (2010) reiterated the ineffectiveness and poor performance of automation systems in the company of errors and uncertainty sources. This suggests, and was considered equally by Paglione and Oaks (2009) and Vivona et al. (2010) that the performance of these systems is dependent on the accuracy of the TP. Consequently, the requirement to minimise all potential error sources has particular precedence in current research. Environmental factors (wind, temperature, air pressure, etc. ), along with human errors and algorithmic/system imperfections are the typical causes for the uncertainty in a prediction. Further error sources such as: the measurement of aircraft state; aircraft performance models; knowledge of aircraft guidance modes and control targets; atmospheric model; and, clearance issues are all predicted to be integral to the improvement of TP modelling accuracy in the near future (Jackson 2010). Alternatively, rather than striving for a flawless system, processes such as the offline smoothing algorithm (Paielli 2011); application of the rapid update cycle (RUC) of the weather (Lee et al. 010); and techniques that take the perspective of the DST user [Interval based sampling technique (IBST)] (Paglione and Oaks 2007) have been established to improve aspects of a prediction model. The first of these has the capacity to improve the accuracy of DR predictions through the smoothing of the radar tracks (shown below). Blue dots Way-points Black full-line Actual path of aircraft Red curve Smoothing of track Blue dots Way-points Black full-line Actual path of aircraft Red curve Smoot hing of track This was demonstrated through application of the technique on past recorded operational error cases. The usage of RUC provides ATC with the benefit of detecting ‘regional variations of uncertainty that are related to actual weather phenomena’ (Lee et al. 2010, pp. 14). The concept behind IBST is that a trajectory provided to a controller may be old and thus filled with errors and uncertainties; so, this two-step process operates by determining the accuracy of the aircraft – through computing spatial errors – after passing through pre-determined waypoints (Paglione and Oaks 2007). Additionally, given the effect of environmental factors on a prediction, there are procedures present to counter the influence of the sources. Russell (2010) presented the ‘consolidated storm prediction for aviation’, which is a prediction on the water content of clouds done through a grid-based prediction which may forecast predictions anywhere up to 8 hours. Results showed that this system was effective up to 2 hours as the predicted data correlated well with the observed weather within a given sector; however, as expected, when the look-ahead time increased the accuracy and reliability steadily decreased. IV. Conflict Detection and Resolution A. Conflict Detection There has been a quantity of research on CDR within this literature, particularly over the last few years (Denery et al. 2011 Erzberger et al. 2009; Tang et al. 2008 and Paielli 2008). In order to overcome the problem of ensuring air safety, technology must exist which prevents a conflict from occurring. A conflict, in an aeronautic context, as described by Paglione and Oaks (2009) is a situation where two or more aircraft exceed the minimum separation distance standards, which can be deduced through a visual TP. The purpose of CDR systems is to alarm ATC well in advance of a predicted collision occurring to allow preventative measures (Erzberger et al. 2009). Paielli (2008) believes that the key challenge in the next decade will be to establish an automated system that is capable of ensuring that the collision probability remains low, even in the face of a number of possible hindrances: i. e. the predicted increase in air traffic in future decades; the (at times) complexity of the system; frequent false alarms; and, the capability of CDR tools to advise the most appropriate manoeuvre. Three of the most highly regarded and reviewed conflict systems amongst ATC (Tang et al. 2008; Paielli 2008; Paglione and Oaks 2009; and Erzberger et al. 2009) are Tactical Separation-Assisted Flight Environment (TSAFE), Conflict Probe (CP), Conflict Alert (CA), and User Request Evaluation Tool (URET). TSAFE has two primary functions 1) conformance monitoring – a process that determines the degree to which an aircraft is meeting its earlier prediction; and 2) trajectory synthesis – the construction of the 4D path. URET was developed to help air traffic controllers by supporting a greater number of user-preferred flight profiles, and increasing both user flexibility and system capacity. ERAM is a Federal Aviation Administration system that has been designed primarily to deal with both route requests and in flight alterations swiftly. Figure 1: Poretta et al. (2010) Figure 1: Poretta et al. (2010) Paglione and Oaks (2009) highlighted the correlation between a TP’s accuracy and a decision supports tool’s (DST) performance. They assessed a number of statistical analysis models including TP metrics (i. . horizontal and vertical) and conflict probe metrics (Along-track; Cross-track; horizontal error; and, altitude). They focus on and use these accuracy metrics to establish a ratio value. Ratio= Horizontal or vertical separationMinimum allowed separation distance (i. e. parameter cut off value) As this ratio increases, the likelihood of producing false and missed conflict alerts increas es– while the probability of producing valid alerts decreases. In Paglione and Oaks (2009) they identified the requirement for a ‘process improvement model’ – i. . Plan-Do-Study-Act (PDSA) – to evaluate and find possible enhancements on a studied TP system to reduce the ratio value. Investigations into false alerts and missed conflict detects have also been conducted recently by Denery et al. (2011) and Poretta et al. (2010). Processes Decisions Data that may be modified Data that may not be modified Algorithm execution flow ——- Data flow Processes Decisions Data that may be modified Data that may not be modified Algorithm execution flow ——- Data flow The latter presented a CDR algorithm (figure 2) which shown by numerical results, is able to produce a conflict-free trajectory whilst also noting the aircrafts capabilities to perform all recommended resolution manoeuvres. Figure 2: Poretta et al. (2010) Figure 2: Poretta et al. (2010) Figure 3: Denery et al. (2011) Figure 3: Denery et al. (2011) Denery et al. (2011) highlighted consequent issues to the above problems – principally, the distraction of controllers and the need to constantly verify whether a concern exists or not. In reply, they proposed a new algorithm, flight-intent (FI) that takes into consideration the present status of the aircraft and all available intent data. Tests were performed with this system in comparison to two other conflict detection algorithms: dual trajectory algorithm (Dual) and dead reckoning (DR). Results (figure 3) illustrate that the FI algorithm yields considerably less false alert rates, especially when the algorithm – already incorporated with area navigation (RNAV) and a noise integrated routing system (NIR) – was paired with the integrated administration and control system (IAC). B. Conflict Resolution Additionally, Anonymous (2010) also noted that two of another CDR systems (conflict probe) faults – including conflict alerts – are that the technology is at times inefficient and will occasionally produce false alerts (or conversely, the lack thereof alerts). The CP’s performance is also compared to URET in tests performed by Santiago et al. (2010). Deductions that were made from this report included the possible benefits of increasing both the look-ahead time of a prediction to 25min, and the minimum horizontal parameters. Further investigation (Paielli 2008; Paielli et al. 009; and Denery et al. 2011) with TSAFE has been ongoing with the aim to develop an algorithm to perform at least as effectively as URET. Ryan et al. (2008) also looked at achieving this goal. They analysed and compared an emerging conflict resolution algorithm, ERAM, against URET in a quantity of tests and comparisons that were designed to evaluate the precision of th e technology. ERAM’s accuracy and strategic conflict notification capabilities were belittled in comparison to the URET system, where ERAM only managed to obtain the minimum standard in two of the seven test categories. TSAFE is often used as a back-up strategic system that computes simple resolution manoeuvres to resolve potential conflicts that are expected to occur within two minutes (Denery et al. , 2011; Paielli et al. 2009; Alonso-Ayuso et al. 2011). TSAFE and its application during en route is the primary focus of Paielli (2011). Examined in his work was the heading-trials algorithm that he developed. This system produces a number of possible manoeuvre resolutions that change the heading of the involved aircraft in  ±10? increments up to  ±90? f the original direction of travel. The best of these manoeuvres – in terms of cost and applicability – is then measured against the best altitude manoeuvre by means of a separation ratio (see pp. 4). His experimentation was on 100 past operational error cases where a conflict had occurred. His results (shown on table 1) illustrate the effectiveness of each manoeuvre in each particular situation. Consequently, he was able to deduce tha t altitudinal amendments were far more advantageous than his proposed heading algorithm. For e. g. the right most column indicates that when the separation ratio was ? 1. 2, 95% of the altitudinal amendments resulted in a successful avoidance of conflict, whilst the heading algorithm only resolved a comparably low 62% For e. g. the right most column indicates that when the separation ratio was ? 1. 2, 95% of the altitudinal amendments resulted in a successful avoidance of conflict, whilst the heading algorithm only resolved a comparably low 62% Separation ratio (? ) %| | 0. 2| 0. 4| 0. 6| 0. | 1. 0| 1. 2| No resolution| 98| 92| 74| 25| 0| 0| Heading only| 99| 95| 91| 77| 71| 62| Altitude only| 100| 100| 100| 100| 99| 95| Heading + altitude| 100| 100| 100| 100| 100| 98| Table 1: Paielli (2011) Table 1: Paielli (2011) Similarly, Paielli (2008) performed a comparable experiment with a restricted focus on altitude manoeuvres. His results further validated the success of such resolution procedures, particularly when augmented altitude amendments were supplemented to the input data (see table 2). The purpose of adding these amendments in his experiment was to compensate for the controllers negligence or inability to do so at the time of the conflict occurring. Note: Other tests and procedures that were tested in (Paeilli 2008) are not shown, i. e. altitude rejections; temporary altitudes; step altitudes; and, critical level-offs.

Given the importance of conflict detection and resolution it is important that ample research continues in this field to ensure the safety and welfare of all air traffic. V. Techniques and Technologies A. Technologies CDR could not be possible if there wasn’t the appropriate equipment present today to compute the complex algorithms that are used. A 4D TP is established upon no easy means. Cate et al. (2008) articulate that it not only requires (at times) convoluted formulas, but also the technology and methodologies to then dissect and string together the state and intent data of the aircraft. The techniques and technologies currently utilised are crucial in this field. Already discussed above are a number of systems which are integral to the concept of trajectory prediction as they all serve a specific purpose. This is exemplified when looking at the conflict detection and resolution component of this literature, where there are often four stages to the process: 1) Traffic collision avoidance system (TCAS) which focuses on the immediate future (1-2min) (Paielli 2011); 2) Short term conflict alert (STCA) which operates anywhere between 2-5min (Shakarian and Haraldsdottir 2001); 3) Tactical controller tools (TCT) which concentrates on up to 8-10min (Leone 2009 and Graffica 2009); and finally, 4) Mid-term conflict detection (MTCD) which will look ahead anywhere up to 20-30min (Graffica 2009 and Lymperopoulos et al. 010). Systems that look any further in advance typically become ineffective due to the dependence of their predictions accuracy on look-ahead time (Russell 2010). Prediction accuracy ? 1Look ahead time Huang and Chung (2011) presented a TP model through their Heirachical timed coloured Petri net (HTCPN) models that is composed of seven different stages during the aircrafts trajector y. This model differs from those that have been presented by (Cate et al. 2008 and Paglione and Oaks 2009) in that 1) their models consist of a three-stage process; and 2) far more input information is required to produce a trajectory. Different still, a TP model has been shown to be represented by an algorithm with many procedures covering difficult mathematical equations of motion (Lymperopolous and Lygeros 2010). As would be expected, with such an intricate form of technology comes a quantity of DSTs, modelling techniques and algorithms to go with it. We require a large range of prediction technologies to both further aid the pilot and ATCs and to meet the particular needs of the interested automation concept (Cate et al. 2008). Tests and comparisons on differing DSTs are continuing (Denery et al. 2011; Vivona et al. 010; and Pagilone and Oaks 2007) and they have confirmed that with the inclusion of particular technologies, a TP system can have an improvement in accuracy without sacrificing either functionality or efficiency. The use of mathematics and observations are verified for two important TP filtering methods: Kalman Filtering (KF), and Particle Filtering (PF) [Lymperopolous and Lygeros (2010); Lymperopol ous et al. (2010) and Delahaye and Puechmorel (2009)]. There are two differing key issues between the two filters – i. e. the inability to handle either high dimensional states or non-linear dynamics. Consequently, a new filtering algorithm, sequential conditional particle filter, was proposed to resolve this problem. Pan and Schonfeld (2009) also explored this technology, demonstrating through ‘splitting a graph with cycles into several directed cycle-free subgraphs’ its enhanced performance compared to other current methods of particle filtering. B. Techniques Data shown by Denery et al. (2011) illustrate the considerable improvements of accuracy and efficiency between their tested algorithms (Dual, DR and FI) with the inclusion of systems such as IAC, NIR, and RNAV (see pp. ). The concept of TP interoperability between systems has also been considered as a potential point of source for advancement in this field (McNally et al. 2010 and Cate et al. 2008). In short, this concept consists of two (or more) unlike automation systems which may compare their disagreeing trajectories and data to result in a similar prediction. This would prove particularly beneficial for a ir-to-ground base control and traffic flight management due to correlation between the two systems. Mujumdar and Padhi (2011) provided an overview of seven encouraging online path-planning methods tested by unmanned aerial vehicles: graph search, potential field method, vision-based neutral networks and minimum effort guidance to list a few. Two common advantages amongst these methods were the ability to compute promptly without the expense of accuracy and the capability to account for environmental information through regular trajectory updates. These benefits correlate well with the necessities of a sought-after algorithm. Modern research is making serious headway towards establishing sound modelling procedures. This is critical as without the appropriate technologies and methods to compute the mathematical representations and data, innovations in this field would not be conceivable. VI. Critical Assessment It rapidly became apparent the quantity of research that has already been done (especially in the past 2-3 years) and that research is still ongoing. The universal desire to constantly improve on each individual part of a TP modelling process is confirmation of its vital importance in not only contemporary society, but our future airspace. The range of exploration and advancements in this literature is both comprehensive and widespread. Every few years, it seems each component of a TP model is enhanced to accommodate for the rapid innovations in modern technology; consequently, this then allows for additional research and analysis in search of further improvements. There were often limitations in the tests that were performed, as often only one (sometimes two) type of aircraft were used during experimentation. The data also, is often decorated by removing plenty of outliers from the tight parameters set. If current research is to progress any further, we must divert away from the existing trend of producing monotonous findings with similar solutions in reports and journals, i. e. modifications to current methodologies; more convoluted analysis; or simply, the suggestion that ‘further work needs to be completed in this area of study’. VII. Conclusion and Open Questions Current research into the TP algorithms that are used specifically for CDR are continuing due to its significance in this field; though, there is a lot of further study required to effectively manage the increasing number of challenges facing ATM in the foreseeable future. For this to occur, the modern techniques and prediction models that are employed must be innovated and evolved even further. The present technologies utilised in constructing a trajectory prediction appear to be effective. Similarly, the techniques which are employed to improve any imperfections or inaccuracies during the modelling process are very specifically designed to serve their own designed purposes. Even still however, the greatest obstacle that needs to be overcome – and surely, where further research must be applied – is reducing the overall effect of error sources and subsequently reducing the uncertainties in the predictions. Given the recent growth of advancements in this field, one may expect that both researchers and developers will be able to competently confront any arising issues in this field of aeronautic technology. In conclusion, a few unanswered questions are immediately brought to mind: * To what extent will the role humans play as decision support systems in response to any complications following any possible system malfunctions or incompetencies. * Does there exist a minimum set of constraints for a given prediction, such that an algorithm is simply unable to compute with any assuring accuracy? If so, how could this be dealt with. Such queries may have place in further study as they are outside the scope of this review. VIII. References 1. Denery, D. , Robinson, J. , Tang, H (2011).

Managerial Economics Analysis of the Indian Telecom Sector Essay Example For Students

Managerial Economics: Analysis of the Indian Telecom Sector Essay PROJECT REPORT ON MANAGERIAL ECONOMICS ANALYSIS OF TELECOM SECTOR IN INDIA INTRODUCTION India is the fourth largest telecom market in Asia after China, Japan and South Korea. The Indian telecom network is the eighth largest in the world and the second largest among emerging economies. At current levels, telecom intensiveness of Indian economy measured as the ratio of telecom revenues to GDP is 2. 1 percent as compared with over 2. 8 percent in developed economies. Indian telecom sector has undergone a major process of transformation through significant policy reforms. The reforms began in 1980s with telecom equipment manufacturing being opened for private sector and were later followed by National Telecom Policy (NTP) in 1994 and NTP1999. The liberalization of the industry has created an impressive forward-momentum in India, resulting in a vigorously competitive and fast growing sector. Moreover, the government had relaxed significantly the foreign investment norms in the sector. According to the Department of Trade, India’s investment policy framework permits foreign direct investment (FDI) in a number of key sectors of the telecom markets. The benefit of this liberalization has been the drastic reduction in call charges. Where a 1 minute trunk call cost Rs. 30 earlier now it costs on Rs. 1. Due to the entry of BSNL and MTNL, cellular telephony costs have also come down rapidly. According to the latest data issued by the Cellular Operators Association of India (COAI), the industry association representing all GSM operators, the number of Indias GSM subscribers had touched 136 million as of the end of June 2007-recording an addition of 5. 4 million during June, or a growth of 4. 2% when compared to 130. 1 million at end-May 2007 The Unified Access licensing regime implemented in the year 2003, gave a major boost to this industry as it permitted basic and/or cellular mobile service using any technology. And today, India is one of the fastest growing markets for Global System for Mobile Communications (GSM) with its subscriber base increasing from 53mn in October 2005 to 116mn in June 2007. If India has to fulfill its full potential of becoming a key player in the New Economy and merge as an IT superpower, it requires a strong and competitive telecom sector. Over the last ten years, significant developments have taken place in this sector and many more profound changes are expected to take place in this industry in the coming years. At present, India constitutes one of the world’s largest telecom markets. Although with a fixed telephone network of 29 million lines, India is ranked as one of the top ten-telecom networks in the world, its telephone density of 2. telephone lines per 100 persons compares unfavorably with global standards. The US has a teledensity of 50 telephone lines per 100 persons; Brazil has a tele-density of 10 telephone lines per 100 persons with the global average being 11 per 100. The current low tele-density offers telecom companies substantial growth opportunities in India and gives the country an option of adapting new technologies. The New Telecom Policy of 1999 (NTP 9 9) has set a target of increasing tele-density to 15 per cent by 2010. Large investments in telecom sector are in process and additional investments are expected, following opening up of national and international long distance segments, permission of unlimited competition in basic telecom services and issue of fourth cellular licenses. Internationally, the per capita investments in telecom industry have increased in the countries with low teledensity. However, policy uncertainty could adversely affect investment plans of telecom operators. Further, long gestation and break-even period would affect the borrowing capability of telecom operators. Over the medium term, the telecom operators would have to infuse equity to meet the fund requirement for roll out of projects. Profitability of the incumbent PSUs is expected to decline from the current high levels, while the new players are expected to register negative cash flows in the medium term. The total revenue in the telecom service sector was Rs. 86,720 crore in 2005-06 as against Rs. 71, 674 crore in 2004-2005, registering a growth of 21%. The total investment in Telecom services sector reached Rs. 200,660 crore in 2005-06, up from Rs. 178,831 crore in the previous fiscal. Telecommunication is the lifeline of the rapidly growing Information Technology industry. Internet subscriber base has risen to 6. 94 million in 2005- 2006. Out of this 1. 35 million were broadband connections. More than a billion people use the internet globally. Under the Bharat Nirman Programme, the Government of India will ensure that 66,822 revenue villages in the country, which have not yet been provided with a Village Public Telephone (VPT), will be connected. However doubts have been raised about what it would mean for the poor in the country. It is difficult to ascertain fully the employment potential of the telecom sector but the enormity of the opportunities can be gauged from the fact that there were 3. 7 million Public Call Offices in December 2005 up from 2. 3 million in December 2004. The value added services (VAS) market within the mobile industry in India has the potential to grow from $500 million in 2006 to a whopping $10 billion by 2009. OBJECTIVES One of the main reasons to undertake telecom markets has been the unique characteristics of cost and demand structures within the telecom sector. One important economic reason for regulation is to help achieve the optimum level of production from a societal point of view, i. e. , to ensure production of the desired products and services in the desired quantities and at appropriate prices for all consumers desiring them. The need for regulation depends on the ability of the market to create this situation by itself. The first basic question is whether production should be organized as planned production with possible corrections by the market, or production should be determined by the market with possible corrections from planners or regulators. THE COST STRUCTURE OF A TELECOM NETWORK The telecom sector is characterized by very large investment costs. The precise percentage of total costs attributed to investments depends of course on the definition of investments and of telecom activities (e. g. whether research, marketing or similar activities are included). Although some sources claim investment, and investment-related costs to be as much as 90 percent of the costs of production, most estimates based on financial data, however, vary between 60 and 75 percent. Thus, by all measures the telecom sector is comparatively capital intensive. For an assessment of the cost structure’s impact on market conditions, more than the level of investments in telecom is relevant. The type of investments is also important. A notable part of the investments are what economists refer to as â€Å"sunk costs†. These are long term investments which can be used only for specific economic activities. An example is a fixed access network providing subscribers’ access to the local exchange. This investment only has value for the supply of telecom services in this particular local area. Once the investment is made the operator can only exit this particular market at considerable costs. Other investments have a shorter time horizon and/or can more easily be applied for other activities. Investments in telecom networks divide into the following functional elements: * Terminal equipment| * Access Network| * Switching| * Transmission/Long line| * Other (buildings etc. ) | TRENDS IN INVESTMENT COSTS The most important factors of input to investments in telecom networks are electronic equipment, cables and wires. Prices for electronic equipment have decreased rapidly and are expected to continue declining in the future. This affects in particular the costs of switching but transmission is affected also. Improved cable technology, and in particular the introduction of optical fibers, has reduced costs of cables substantially. Prices for copper wires are relatively stable, but new compression techniques are increasing its capacity. Optical fiber cable provides significantly greater capacity, and price reductions now make it competitive with copper cables for installation of new access networks on Greenfield sites in some locations. However, at present it is not economical to replace installed copper cables. In the access network the laying of cable and wire constitute as much as 90 percent of the costs. Thus the cost of the cable itself plays a diminishing role. But in the transmission network, where the increasing capacity of optical fibers can be utilized more advantageously, fiber cable will have a substantial impact. DEMAND Demand for telephony has a very low sensitivity to changes in tariffs, but more expensive services such as long distance telephony tend to be more sensitive than local telephony, which is more of a necessity. Another characteristic for both telephony and many other communication services is the positive externalities created by the service. A completed telephone call requires the participation of a second party, which in most cases also is benefiting from the call (call externality). Another externality arises when a new subscriber is connected to the network. This will benefit all other subscribers which possibly could have a need to communicate with the new subscriber (access-externality). This point is very important for the introduction of new services. New services need to establish a critical mass of network subscribers before they really can become useful and the market can unfold. Telecom services are offered to two distinct groups of customers with quite different patterns of demand:- * Business Customers| * Residential Customers. | CONDITIONS FOR EFFECTIVE COMPETITION In economic theory, the notion of perfect competition is used to characterize an unregulated market where the forces of competition drive down prices to the level of production costs, and both price and production develop in such a way that the societal welfare is optimized. Such a market can be established if the following conditions are met; sufficiently large numbers of independent suppliers; sufficiently large numbers of independent consumers; free and easy entry and exit of suppliers; and full visibility of market conditions. It is not at all clear whether the telecom markets are likely to get close to meeting these conditions. If all these conditions are not fulfilled, the market cannot by itself optimize production. In this case it may become necessary to develop regulatory measures, which can â€Å"help† the market function more closely to the optimal condition. However, it may be very difficult for new suppliers to enter the market. The most important barriers to entry which restrict the number of suppliers are: * Economies of scale| * Economies of scope| * Economies of density| * Size and flexibility of investment| ECONOMIES OF SCALE Economies of scale reflect the opportunities for reduced unit costs with increased output. They provide efficiency advantages for large units of production and new entrants will find it difficult to compete with already well established firms with large scale production. If production of a certain service involves considerable economies of scale, new firms will find it difficult to compete with existing firms that have a well established large scale level of service supply. Furthermore smaller companies will tend to merge into larger units to remain competitive. Therefore, an unregulated market is likely to result in a very limited number of large scale suppliers. ECONOMIES OF SCOPE Economies of scope are defined as cost savings related to supplying a number of different services by the same company. Economies of scope can be a barrier against smaller companies only supplying a limited range of services. This could be a local operator or an international carrier. Three different types of economies of scope can be distinguished: * Economies of horizontal integration | (e. g. telephony and data)| * Economies of vertical integration within the network| (e. g. local and long distance)| | * Voice and value added network services | (e. g. call forwarding)| | * Economies of vertical integration beyond the network| (e. g. information production and distribution). | | Economies of scope can also arise in billing and customer relations. Operators supplying a full range of services can offer their customers one stop shopping and one stop billing. This gives an advantage compared to service providers specializing in a few areas. It is a factor influencing global alliances in telecom to meet the demands of global transnational corporations. ECONOMIES OF DENSITY Economies of density are related to the fact that network costs per connection decreases with increasing density of connections. The primary reason for this is shorter access lines and better capacity utilization of the network. Economies of density imply that it is very difficult for newcomers in an area to compete with a former monopolist, where local networks with a high penetration already have been established. This is of course particularly important in the residential market, where the revenue per customer is much lower than in the business sector. A newcomer may either build its own infrastructure from scratch or buy parts of its capacity from the incumbent operator. In some instances a duplicate network infrastructure can be built on top of other types of infrastructures e. g. local cable-TV or electric power networks. But even in these cases considerable investments must be made before sufficient economies of density in supplying interactive network services can be achieved. From a regulators point of view the barrier created through economies of density can be overcome either by supporting the building of alternative infrastructures e. g. right of way access, tariff regulations, taxation of the incumbent operator or other approaches. Or regulatory measures can be enforced in order to ensure competitors fair access to existing network facilities. The first solution may promote short run competition most directly. But if there are significant economies of density it may be a costly solution as it implies a substantial duplication of network investments. Furthermore it is probable that this competition will be eliminated in the long run as the competitors are driven toward more efficient arrangements for meeting consumer demands. DEMAND-RELATED FACTORS Demand for telecom services evolves from a core demand for a homogenous output – basic telephony – for which pure transmission is the common ingredient in a wide range of services, where transmission often is combined with other service functions. Increasingly these services are offered by service providers other than the provider of the basic transmission services, usually the incumbent PTO. Other producers may be foreign telecom operators, computer companies or companies from another industry. Cost structures differ for different services, and market structure depends a great deal on the type of service demanded. Cable based transmission intensive services with a low level of processing involve relatively higher sunk costs than processing intensive services, where substantial value is added to the basic transmission. So far, increased demand for new services has tended to change the overall cost structure in the direction of a reduced share of costs for transmission and an increasing share on processing and value added components. This implies a decreasing role of sunk costs and better conditions for stimulating competition at least in the value-added segment. Advanced services provided for large business customers are less dependent on services from the network operator. If special facilities are needed, special network solutions can be designed on a network of leased lines. This development may not be feasible for services designed for residential customers. Advanced residential services must rely on transmission facilities as defined by the local network operator. As the existing cost structure implies that basic residential services is the area where there are the greatest barriers to developing effective competition, diffusion of such services may be restricted to a pace determined by the local PTO. Positive externalities related to usage and access imply that consumers depend not only on the network operator but also on the behaviour of other consumers. Call and access externalities give telecom services the character of a public good. Therefore, a free market may result in production and usage of services below the social optimum. This problem is partly addressed for basic telephony by imposing on the operators a universal service obligation, but the problem may be more acute in relation to new services where obtaining a critical mass large enough to make the service attractive can cause difficulties. This barrier can be overcome by public initiatives, such as the generation of public demand and standardisation. However, it may be difficult beforehand to foresee which services deserve public support. LITERATURE NATIONAL POLICY Till the early 1990s, the government enjoyed full monopoly over telecom services with the Department of Telecommunications (DOT) being the sole provider of telecom services (local and long distance) in the country, except in Delhi and Mumbai, where Mahanagar Telephone Nigam Ltd (MTNL) was the sole access provider. International services were provided exclusively by the Videsh Sanchar Nigam Ltd (VSNL). In 1994 the Government of India issued its National Telecommunications Policy. The policy was issued in recognition of the urgent need to provide universal access to basic telecommunications services by 1997 and offers guidelines for entry of the private sector into basic telecommunications services. To facilitate private-sector participation, licensing procedures were established in the Department of Telecommunications in India, and equity participation for companies registered in India (with 51 or more percent Indian ownership) was anticipated. Private-sector licenses, however, were to be granted only for local (versus long-distance) telecommunications networks. An autonomous body, the Telecommunications Authority of India, was established to regulate private-sector activity. NEW TELECOM POLICY 94 The first step towards opening the telecom services sector took place with cellular licenses for the four metros being awarded to private companies in 1994. In the same year, the government formulated the National Telecom Policy of 1994 (NTP 94) with the objective of expanding the telecom infrastructure by encouraging private sector participation in telecom services. As per NTP 94, one private company per circle was to be allowed entry into basic services while two operators were to be allowed to compete in providing cellular services in each of the circles. Subsequently, cellular services became operational in four metros and 18 state circles and basic services, too, commenced in a few circles. However, high license fee bids, tariff distortions, unattractive interconnection and revenue sharing arrangements between DOT and new private licensees resulted in most service providers finding themselves in financially unviable situations. NEW TELECOM POLICY 99 In an attempt to remove the defects of the old policy and provide a new direction to the telecom sector, the government came out with NTP 99. The highlights of NTP 99 are: * Private basic and cellular operators allowed migrating from revenue sharing regime to one time entry fee plus revenue sharing system. | * License period extended from 10 to 20 years. | * DOT’s monopoly over domestic National Long Distance (NLD) services to end in 2000. | * Interconnection between fixed, cellular and other telecom service operators to be allowed freely. * Indian Telegraph Act, 1885, to be replaced by a new legislation| THE TENTH PLAN (2002-2007) During the 10th plan period (2002-2007), the Government targets to add 81. 71 million lines (including fixed and cellular), which translates into the teledensity of 11. 5 per cent in 2007. The Government has envisaged the total investment of Rs 1,606. 7 billion including the telecom investment of Rs 441. 6 billion in rural area s and Rs 462. 9 billion investment by the private operators. In order to accelerate the growth of private investment in telecom industry, the working group on Information Technology has proposed key measures like establishing interconnection agreements, meeting the requirements of USO fund, utilization of license fee for rural telephony, incentives for roll out in the rural areas, decision on calling party pays regime etc. RECENT POLICY CHANGES:- NEW LICENSES FOR BASIC TELECOM SERVICES In January 2001, guidelines for the entry of new fixed service providers were announced. Out of the applications by 18 companies, 6 companies were issued LoIs for basic telecom services. By March 2002, 3 companies including Reliance (17 circles), Tata Teleservices (5 circles) and Bharti (4 circles) had signed license agreements by paying the total entry fee of Rs 8. 39 billion. FOURTH CELLULAR LICENSE In October 2001, the Government issued licenses to successful bidders for commencing cellular services. These include, the Bharti Group in 8 circles, Escotel in 4 circles, Hutchison Essar in 3 circles, and Reliance (through Reliable Internet) and Birla-ATT and Tata in 1 circle each. A Banjo Player's Journey EssayThe change in price by some amount will make consumer to shift to other service provider, or to reconsider idea of using mobiles. So the consumer is more or less price relatively elastic this can be seen from the above graph. CONSUMER BEHAVIOR Consumer theory is a theory of economics which relates preferences, indifference curves and budget constraints to consumer demand curves. It is theory which deals with reconciliation of dreams and our budgets. Consumer theory can be used in order to estimate the optimal goods bundle for an individual buyer. India is completely a different kind of market. People of India are more conservative as compared to other western countries. Taste and preferences of people were more rigid and flexibility of consumer to adapt to changes was less. But with the high rate of development, taste preferences of people have started changing. With increase in consumer income the influence of western high life style the way of thinking has started changing. In case of telecom people were more skewed to voice than that of the services provided to users. People’s perception regarding phoning was only limited to use voice services. But gradually there has been a change in the behavior of consumers. People are also interested on new services provided to them. Services such as MMS, internet, broadband services, etc. form a major role for a consumer to select a particular service provider. This shift in the mind frame of people can be depicted through concept of indifference curve. INDIFFERENCE CURVE Indifference curve is locus of points that shows different combinations of two products that yield exactly the same level of satisfaction. The two products in case of telecom services are Voice and Data. Now in graph we have curve U1 as indifference curve. On this curve the consumer is satisfied if he gets voice and data in range of A-A’. Either he can be at point E or E’. But outside the range A-A’ he will not be satisfied as he has some minimum voice requirements. In range A-A’ voice and data can be substitute for each other to some extent i. e. bad Voice quality can be compensated by Data service (SMS). Income Effect In this concept of indifference curve, we have an income effect. As long as the prices remain constant, changing the income will create a parallel shift of the budget constraint. Increasing the income will shift the budget constraint right since more of both can be bought, and decreasing income will shift it left In the above diagram, initially we have U1 as the indifference curve where the consumer attains his equilibrium at point A, where he consumes a certain level of voice data. But with increase in disposable income initial budget line of consumer shifts from DV to D’V’. In response to this shift in budget line the indifference curve shifts to U2. From this we should conclude that along with budget line consumer affordability has increases and there is a shift in indifference curve. Change in preferences Initially when the mobile phones were introduced their main objective was to offer voice services. But with advancements in technology and requirements of better and other communication modes the demand by consumers Data services increased. There was a shift in preference on services used by consumer. Consumer transformed himself from a voice centric user to a balanced user (using both voice and data simultaneously). In recent past the use of mobiles was restricted to Voice calls, messages, low speed data connectivity, etc. This is shown by indifference curve U1. As shown in the graph on this curve U1 the consumer wants to operate in region A-A’ because he can only be satisfied if he gets some minimum voice services. i. e. if voice services fall below certain level the consumer is not satisfied. On this curve U1 is point E which gives the exact amount of voice and data services utilized by a consumer. Now in the present situation the consumer requires more data services in addition to voice services which he utilizes. So his overall utility has increased this means he has shifted from lower indifference curve to higher urve U2. On this new curve the consumer wants to operate between points B-B’. On curve U2 is point E’ which gives the new quantity of data and voice used by consumer. So here we conclude that due to increased requirement of data services, and affordability of these services consumer has moved from point E to point E’. Also we can see, primarily only the voice services that overshadows data related se rvices, but ultimately indifference curve shifts to a higher level, which led to an increase in consumption of both data voice services. India will have 650 million subscribers by 2012The Government has set a target of providing 200 million rural telephony connections, which will increase rural tele-density to 25 per cent from the current level of 1. 7 per cent. Pointing out that the telecom sector has been the biggest success stories of market-oriented reforms, the Economic Survey has projected that telephone subscribers base will more than treble to 650 million users by 2012. It envisaged that Internet and broadband subscribers will increase to 40 million and 20 million respectively by 2010. Telephony subscriber base up The subscriber base for telephony services continued its growth during March 2007 with 3. 93 million subscribers being added during the month. A total of 66. 51 million subscribers were added during 2006-07 as compared to 41. 91 million in 2005-06, registering an increase of 58 per cent, a TRAI release said. This is the highest ever increase in subscribers during a financial year after the opening up of the telecom sector for competition, it said. Wireless service subscriber base increased by 3. 53 million in March 2007 as compared with 6. 21 million in February. In the wireline segment, a total of 0. 0 million subscribers were added during March 2007 as compared to a decline of 0. 02 million in February 2007. Indian to have 1 million Net TV subscribers by 2011 India is expected to be the fifth largest Internet Protocol Television (IPTV) market in the Asia-Pacific region (excluding Japan) with nearly a million subscribers by 2011. However, low quality bandwidth and poor penetration o f broadband could result in slow uptake of the service in India, according to a new forecast from IDC. At present, India is nowhere on the IPTV map with just over 9,000 subscribers. IDC expects over 49,000 IPTV subscribers in India by the end of 2007 with the number expected to grow to reach 966,000 subscribers by 2011. China is expected to have more than 14 million IPTV users by that time. BSNL aims for 500-million subscriber by 2010 BSNL is aiming to touch more than 500-million subscriber base for mobile and fixed-line connections by 2010. Union Minister of State for   Communications Information Technology Dr Shakeel Ahmad   said the BSNL has already touched a subscriber base of 210-million including 165-million mobile customers. We have set an ambitious target of taking it to 500-million   mark by 2010. Of the 500-million customers, we plan to add 200 million mobile customers across the country,† he claimed. However, Dr Ahmad took pains to clarify that despite a rapid growth in the number of   cellphone subscribers in India, importance of fixed-line connections has been increasing as those having landlines will be getting several facilities inc luding IPTV, FLPP, location alarms and a host of other services. India issues 159 telecom licenses 59 licenses have been issued for providing access services in the country and generally there are 5-8 providers in each service area. Since any Indian company can apply for unified access license, this is increasing the demand for spectrum in a substantial manner. Currently, there is no cap on the number of service providers in a service area. There are 23 telecom circles in the country. GSM subscriber base touches 12. 55 cr The GSM-based cellular industry has added over 41 lakh subscribers in April with Bharti Airtel capturing 30. 7 per cent of the market share. With this, the all-India GSM subscriber base has touched 12. 55 crore at the end of April 2007 compared to 12. 14 crore at the end of March 2007, reflecting a growth rate of 3. 40 per cent, the Cellular Operators Association of India (COAI) said in a statement. In April, the cellular subscriber base of Bharti touched 3. 88 cro re with additions of 17. 51 lakh users, followed by BSNL at 2. 77 crore with a market share of 22. 10 per cent and additions of 3. 26 lakh subscribers. Hutch-Essar has 2. 7 crore subscribers, taking its market share to 22. 06 per cent and Idea with a market share of 11. 60 per cent has 1. 45 crore subscribers in April. Hutch-Essar added 12. 61 lakh subscribers in the month of April, while Idea added 5. 52 lakh mobile users in the same month. MTNLs GSM subscriber base in Delhi and Mumbai touched 24. 83 lakh, while Spice Telecom has over 28 lakh subscribers. Aircels user base in April stood at 59. 27 lakh, followed by Reliance Telecoms 43. 47 lakh subscribers. India to reach 600m mobile connections by 2011 Mobile phone connections in India will reach 600 million in five years time as handsets and tariffs become more affordable for the urban population, according to a new study published today by the Centre for Telecoms Research (CTR), London The report expects urban populations of India to reach high levels of mobile phone saturation in five years time, to the extent where many phone users will have two or more handset connections. A large portion of this growth will arise from pre-paid connections, driven by the increasing affordability of handsets and tariffs amongst Indias lower middle classes. The phenomenal growth in the Indian mobile phone market has largely been driven by urban consumption. We expect this to continue with urban geographies achieving saturation levels similar to current Western European markets in the next five years. Mobile connections in rural geographies will be constrained by coverage of network infrastructure and affordability of handsets which will limit co nsumption to no more than 150 million by 2011, said Raj Modi, Research Director at Centre for Telecoms Research. CONCLUSION A few decades ago the market for telecom services was a homogenous market supplying essentially the same service – telephony – to all types of customers. Today the market is becoming much more diversified with an increasing range of services offered by incumbent PTOs, providers of cable-television, data communication companies etc. Most of these new companies have not invested in their own physical infrastructure but rely on network capacity leased from other operators. The most significant barriers to competition are related to the cable and wire-based local facilities network. It seems unlikely that effective competition in this area can be established. In other areas, barriers to entry are less dominant and competition can more easily be established. Long distance and cellular telephony are both areas where competition can more easily be established, and where competition has been successfully introduced. FUTURE TRENDS IN THE TELECOM INDUSTRY Process of change is a continuous phenomenon and these changes are imperative in response to the local and global circumstances. The developing nation like ours encapsulates these developments/changes in the passage of time. India, like many other countries of the world, has adopted a gradual approach to telecom sector reform through selective privatization and has managed competition in different segments of the telecom market. It can be summed up that growth in the number of new telephone subscribers has far exceeded the growth in the global economy in the last two decades. The future trends can be analyzed in many ways that includes: * Focus on rural sector| * Telecom and IT| * Competition of existing players| * Technology trends| FOCUS ON RURAL SECTOR There have been a lot of reforms in telecom sector in India and Indian markets are still growing. The participation of private sector has been constantly increasing and it can be predicted that, the focus in the coming few years would be on the rural sector as the saturation in the urban markets would shift the concentration of markets. TELECOM AND IT India is a participant in this global process. Being a developing nation it has a tremendous appetite to absorb new technology. At the higher end of the market, India will imitate the most sophisticated telecom technology of the world but it will take time for the market for new technologies to consolidate. Market maturing’ is a continuous process in India, the main problem that companies are facing today and will continue face is to retain its customer base. IT in general will be a very important tool to influence the consumer. IT is widely used for Data-mining and Customer relationship management. COMPETITION OF EXISTING PLAYERS As compared to the past, one notable change has been the opening up of the developing economies and because of this the catching up process of the developing nations with the developed ones has become faster. Developing countries with liberal policies have much better opportunity to grow than before, this has given rise to wide spread competition. The global trend is towards growing privatization and competition. India, with her commitment to reforms is already a part of this process. Keeping in mind the global working, as more and more players participate in the process of expansion it leads to disintegration of market, technologies etc but after the disintegration the roles reverses. TECHNOLOGY TRENDS There has been phenomenal growth in mobile subscribers in the world in the last 5 years. Broadly speaking, technologies of mobile telecommunications and Internet are going to set the contours of further technological progress in the current decade and the next. The most recent initiative aims at convergence of voice and data received from multiple sources, both web based and real time video streams, in mobile handheld devices. Global positioning systems, mobile handsets and calling cards have made virtual presence possible almost everywhere and anywhere overcoming the barriers of distance, topography and remoteness. At the uppermost end of the convergent technology spectrum have already emerged Third Generation (3G) mobile devices with the capability of access to mobile data and voice. India, after much of development have only witnessed sets of 2G-2. 5G technology and it would require investment, efforts and up gradation of hardware and software for high bandwidth multimedia services etc. , for India to get into 3G devices. By next 2 years, one would expect 3G to be within reach of wider section of Indian population. SUGGESTIONS Telecom could contribute significantly to the societal transformation particularly in the rural areas by enabling our people to communicate and reap benefits. Till recently, benefits of telecom revolution touched mainly the cities and towns. Now it is time for the telecom growth to penetrate into the rural sector to democratize access and bring happiness and prosperity, overcoming all geographical barriers. Societal transformation and economic growth are closely interlinked. Information society with innovation as focus, transform into knowledge society. This, in turn gives positive impacts in agricultural society and industrial society. The core of empowerment for prosperity of one billion people is the connectivity and partnership between governmental and multiple institutions in the public and private domains. The fast growing telecom economy and infrastructure have to be the primary contributors towards this. While telecom technologies have revolutionized all aspects of society: industry, business, banking, government, judiciary, defense, education, health, agriculture, they have also introduced certain concerns. In the last one and a half centuries of the growth of telecom sector, and the last one century of the growth of wireless technologies, new problems have emerged. Some talk about digital divide and brain drain. We should see the situation positively. Can we convert these problems to digital bridges or digital highways and brain gains? Already some such aspects are visible in the BPOs and even in call centres. Another area needing some assessment and debate relates to invasion of privacy. As we all know, telecom technologies are capable of locating the position of the cell phone, its utilization pattern, and the particulars of the contacts, leaving the individual open to avoidable exposure and exploitation by motivated agencies. Ethics for utilization of telecom tools and technologies also need to be evolved so that individual privacy is not intruded upon. Although some restrictions are in place for unsolicited telephone calls, there is a need for more effective control mechanism. India is lagging far behind with very few households being digitally connected, though four of the top ten broadband economies of the world were in Asia. It appears that that South Korea, Hong Kong, Taiwan and Singapore, which now have the distinction of achieving highest broadband household digital connectivity index of 80 to 60 per cent, have excelled and grown faster than the rest of the world because of significant utilization of local languages in the generation of software and content on the internet. Herein there is a significant message. The large-scale utilization of local languages will enable people to create content with ease and authenticity which, when hared, will have a positive effect in the growth of economy through the benefits of telecom revolution and related Internet and multimedia tools. The Indian E-Governance and E-Commerce initiatives should become the drivers for the rural population to seek information in their local language and thus give a push to telecom penetration in the rural areas. The world over, in the past few decades research and development has been focusing on increasing the bandwidth carried by copper and fiber optic cables and wireless medium without having to change the old cables and infrastructure. The Copper cables that carried a few kilobits when they were first introduced today can carry megabits of information as a consequence of the digital revolution. The fiber optic cables that carried a few megabits initially today can carry several terabits of information with the introduction of Dense Wavelength Division Multiplexing (DWDM). Similar are the trends in wireless communication. Because of this exponential and disruptive growth in the bandwidth, we have reached a stage where bandwidth has become abundant and one can claim that distance has died. The world has not only become flat but has shrunk. THE CHALLENGES First challenge is of the Infrastructure, and for this country’s vibrancy in manufacture, research and development should be fully used to make India truly self sufficient in telecom. The number of cell phones and access devices, routers, switches and modems that this country would need that too in a continuously replenish able fashion is incentive enough to start a strong manufacturing program in telecom. We should project a goal of 70-30 by which more than 70 per cent of the telecom hardware and software should be manufactured in India by 2010. Value-added services provided a great opportunity in telecom is in innovating value added services that run on the telecom infrastructure. With the inherent strength of the nation in software, this should be easy to do provided we concentrate our energies in this direction. This is also a fertile ground for incubating many small starts up companies and this will be a second silicon valley – just the same way the Internet spurred the revolution, today the wireless and the telecom can stir another. This will be a unique experience of India.
