TL;DR: In this paper, the authors take a unique look at telecom access and study the perceived impacts of direct access to telecom services, that is, telephone ownership at a household level at the bottom of the pyramid in five developing Asian countries.
Abstract: Much has been said of the benefits of access to telecommunication especially at the ‘Bottom of the Pyramid’.2 The economic as well as social benefits from such access can, in theory enable people to graduate from poverty and also contribute more widely to development. Thus it can be argued that inequality in access to telecom services can lead to limitations in fighting poverty. Many in the ‘ICT for development’ movement highlight the benefits that telecommunication, the Internet and other information and communication technologies (broadly put, ICTs) can bring to the table in the fight against poverty. A number of studies have attempted to demonstrate the impacts of access on income at the macro-level. However supporting evidence for these arguments at the household level is limited at best. This paper takes a unique look at telecom access and studies the perceived impacts of direct access to telecom services, that is, telephone ownership at a household level at the ‘Bottom of the Pyramid’ in five developing Asian countries. It focuses on the perceived economic impact (positive or negative) of telecom ownership in terms of the potential to increase indirect income generation capacity or save on expenditure or transactions costs. The findings reveal that some telecom users do perceive the economic benefits of direct access to be high, but this finding is not seen across the board for a number of reasons explained. The paper is based on a large sample survey of telecom users at the BOP in Pakistan, India, Sri Lanka, the Philippines and Thailand. Section 2 reviews the existing literature on the impacts of telecommunication. Section 3 explains the study design and methodology, and examines the difficulties faced in conducting a study of this nature and the methodological innovations undertaken. Section 4 explores in detail the impacts of telecom services at the BOP in the five countries. Section 5 concludes, looking at the policy implications from the study.

TL;DR: In this article, the authors present the results of research that aimed to fill this gap by identifying, from a network/international perspective, the opportunities/threats created by the relevant linkages of leading telecom operators in Brazil.
Abstract: In response to competitive pressures created by privatization, telecom firms in developing countries are establishing alliances and other types of linkages—mergers and acquisitions—with foreign partners to ensure customer competitive advantages in global markets. However, there have been very few studies on the alliances of telecom operators in Brazil, an increasingly important BRIC. This article presents the results of research that aimed to fill this gap by identifying, from a network/international perspective, the opportunities/threats created by the relevant linkages of leading telecom operators in Brazil. The results suggest that acquisitions—and especially alliance-type linkages with foreign partners—have created opportunities for boosting performance, in keeping with their new strategic profile.

TL;DR: In the early 1990s, a worldwide wave of liberalization and technological and business innovations in the mobile space, much of the globe is electronically connected, albeit not at the levels that would support full participation in the Internet as discussed by the authors.
Abstract: Full participation in the global Internet economy requires electronic connectivity of considerable complexity. Today, due to a worldwide wave of liberalization and technological and business innovations in the mobile space, much of the globe is electronically connected, albeit not at the levels that would support full participation in the Internet. Yet, many millions of poor people are engaging in tasks normally associated with the Internet, such as information retrieval, payments, and remote computing, all using relatively simple mobiles. Understanding the business model that enabled impressive gains in voice connectivity, as well as the beginnings of more-than-voice applications over mobiles, is important not only because widespread broadband access among the poor is likely to be achieved by extending this model, but because it would be the basis of coherent and efacacious policy and regulatory responses. Voice connectivity was achieved for a majority of the world’s people, including substantial numbers of the poor, because governments removed or lowered barriers to participation in the supply of telecom services and created conditions conducive to competition, even if that competition was less than perfect. This was the necessary condition. Where multiple suppliers existed, intense competition occurred—the critical step in implementing the budget telecom network model. The radically lower prices attracted more minutes of use, which, in turn, made further reductions possible. Operators were able to load their networks with high volumes of revenue-yielding minutes because they had succeeded in reducing the transaction costs of dealing with large numbers of customers who generate small amounts of revenue. Prepaid, which reduces transaction costs and also accommodates the needs of those with irregular earning patterns, was a critical element. Along with these innovations, the exponents of the budget telecom network model also succeeded in drastically reducing both capital costs and operating costs. The new model makes ARPU (average revenue per user) irrelevant, because what really matters is how many revenue-yielding minutes are carried on the network, not how much money is earned from an average customer. In the same way that Ryanair and Air Asia make proats while conventional airlines lose money, budget telecom networks make more money than conventional operators. However, the model does increase the volatility of earnings, and it often results in a lower quality of service.

TL;DR: The conditions of Bangladesh are analysed as Bangladesh can be considered as an ideal model among many developing countries for such type of study and some basic technical and socio-economic problems of access network are identified and some recommendations are made considering the prevailing situations.
Abstract: This paper presents a case study on establishing redundant access networks in the telecommunication sector of a developing country. For this work, we have analysed the conditions of Bangladesh as Bangladesh can be considered as an ideal model among many developing countries for such type of study. We first present the conditions of existing access networks in Bangladesh. Then we compare different access networks in the telecommunications sector and predict the demand for various telecommunication services; such as voice, data, internet, etc. We also design some possible redundant optical access networks considering some important parameters. Though the economic benefits of having a reliable telecommunication infrastructure are numerous, at present Bangladesh is lagging behind in the deployment of appropriate telecom infrastructure and video and multi-service facilities. For this reason, some basic technical and socio-economic problems of access network are identified and some recommendations are made considering the prevailing situations. This work may also be useful for working on similar cases in other developing countries like Bangladesh.

TL;DR: In this article, a rigorous demand model is estimated using global mobile telecommunications panel dataset comprised with 51 countries classified in order to World Bank income categories from 1990-2007, to construct an econometric model, the number of subscribers to mobile phone per 100 inhabitants is taken as dependent variable, while the following groups of variables (1) GDP per capita income and charges, competition policies (2) competition policies, telecom infrastructure, and technological innovations (5) others are selected as independent variables.
Abstract: This study aims to analyze the global mobile phones by examining the instruments stimulating the diffusion pattern. A rigorous demand model is estimated using global mobile telecommunications panel dataset comprised with 51 countries classified in order to World Bank income categories from 1990-2007. In particular, the paper examines what factors contribute the most to the deployment of global mobile telephones. To construct an econometric model, the number of subscribers to mobile phone per 100 inhabitants is taken as dependent variable, while the following groups of variables (1) GDP per capita income and charges, (2) competition policies (3) telecom infrastructure (4) technological innovations (5) others are selected as independent variables. Estimation results report the presence of substantial disparity among groups. Additionally GDP per capita income and own-price elasticity comprised with call rate, subscription charges, are reported. The analysis of impulse responses for price, competition policies, and technological innovations such as digitalization of mobile network, mobile network coverage indicates that substantial mobile telephone growth is yet to be realized especially in developing countries. A new and important empirical finding is that there are still many opportunities available for mobile phone development in the world pro-poor nations by providing better telecom infrastructure.

TL;DR: In this article, the authors investigated the effect of partial and full liberalization on the telecommunication sector, consumers, and the economy at large in Nigeria and concluded that the operation costs and service tariffs of the telecom companies are still very high as a result of constant power outage in the country.
Abstract: After over a century, the Nigeria telecommunication sector was partially and fully liberalized in 1992 and 1999 respectively. How these liberalizations have impacted on the telecommunication sector, consumers and the economy at large is the focus of this paper. The research is largely library and archive based. Secondary data was obtained from Nigerian Communication Commission (NCC) and analyzed qualitatively. The paper reveals that the total telecom productive capacity, number of connected lines, competition, GSM telecom services, service quality, foreign direct investment, and employment generation in the telecom sector have improved tremendously after full liberalization. However, the operation costs and service tariffs of the telecom companies are still very high as a result of constant power outage in the country. The paper recommends that government should increase and sustain electricity generation and distribution capacity so as to enable telecom companies charge lower prices for telecom services. Keywords: Liberalisation, telecommunication, Nigeria, and GSM.

TL;DR: A global architectural and decision support solution for a reaction after alert detection mechanisms in the frame of information systems security applied to telecom infrastructures and a layered view of the infrastructure thanks to MAS architecture, which enables the decision making with different levels of knowledge.
Abstract: The paper provides a global architectural and decision support solution for a reaction after alert detection mechanisms in the frame of information systems security applied to telecom infrastructures. Therefore, the architecture is developed in a distributed perspective and is composed of three basic layers: the low level that constitutes the interface between the architecture and the infrastructure. The intermediate level that is responsible of correlating the alerts coming from different domains of the infrastructure and to deploy the reaction actions. The architecture is elaborated using a MAS associated to the OntoBayes model for decision mechanism. This model helps agents to make decisions according to preference values and is built upon ontology based knowledge sharing, Bayesian networks based uncertainty management and influence diagram. The major novelty of this Decision Support System is the layered view of the infrastructure thanks to MAS architecture, which enables the decision making with different levels of knowledge.

TL;DR: In this article, the authors present an in-depth analysis of the Universal Service situation in Serbia, addressing the economic and geographic digital divide for the introduction of broadband services and recommend basic elements for appropriate broadband access policies for regions as administrative units.
Abstract: This paper presents an in-depth analysis of the Universal Service (US) situation in Serbia, addressing the economic and geographic digital divide for the introduction of broadband services. The authors’ main objectives are to study and present a detailed overview of the state of telecom infrastructure and telecom service provisioning in the whole territory of Serbia as well as to recommend basic elements for appropriate broadband access policies for regions as administrative units. The study methodology includes the situation of locations (settlements) without fixed telecom services and locations with low penetration (4 and 10%), with each settlement having more than 50 inhabitants or more than 20 households. To facilitate implementation, the economic strength of the critical settlements and the necessary US funds are estimated, and the relationship between economic and telecommunication development is evaluated on the level of Serbian municipalities. This relationship indicates to policy makers that telecommunication is an important tool for overall development. Special attention is paid to people with disabilities and low-income users. As Serbia belongs to a large class of medium countries with a middle income and moderate telecommunications, this case study and its findings could be used as a model for other emerging economies. Key words: Telecommunications and economical development, universal services policy, broadband access, people with disabilities, telecommunications policy makers, emerging economies.

TL;DR: A flexible platform for provisioning telecom services that is independent of the underlying communications protocol being deployed is proposed and a proof-of-concept implementation that is developed based on the Parlay X specification for telecom service capabilities and information exposures on top of an IMS network is presented.
Abstract: Web 2.0 has been an integral part of modern societies, providing collaboration functionalities between individuals. Innovative and pervasive nature of Web 2.0 services has led telecom operators to a strong competition with internet content providers as over-the-top applications are getting very popular. Services can be created faster in the Web 2.0 world where anyone can develop. It is in contrast with the legacy telecom infrastructure where services are tightly coupled with the underlying access networks. Recently, telecom operators have been rolling out the IMS, which provides an environment for rapid application development of services. However, applications created on top of the IMS are based on SIP, which is not popular in the Web 2.0 domain. This paper proposes a flexible platform for provisioning telecom services that is independent of the underlying communications protocol being deployed. A proof-of-concept implementation that is developed based on the Parlay X specification for telecom service capabilities and information exposures on top of an IMS network is presented, and a brief overview of the performance is given.

TL;DR: In this paper, the authors provide a general reassessment of basic trends toward openness in telecom reform policies based on experience and future opportunities, as well as the experience has varied among regions and countries.
Abstract: Central to almost all issues of policy and regulation relating to telecom reform, ICT convergence, and Internet development over the last quarter century has been the extent to which a formerly monopolized and closed telecom network will be opened to the participation of those previously excluded The extent of openness and the terms of participation in the telecom reform process have been critical to the successful implementation of virtually all reform policies It is often assumed that the policy path is a continuous evolution toward more openness and participation, as old barriers are knocked down by new policies But this has not been the case, as policy reform sometimes stalls and even retrenches on some policy issues, and as experience has varied among regions and countries This short essay provides a general reassessment of basic trends toward openness in telecom reform policies based on experience and future opportunities

TL;DR: In this article, the authors investigated the most important drivers, barriers and trade-offs considered by the network operators before deciding to share infrastructure and made explicit the important considerations that affect the final decision of the network operator regarding infrastructure sharing.
Abstract: Network operators in mobile service market face new challenges. Their decreasing revenues make them seek for cost reduction. Resource sharing might be a way towards this direction. Depending on the adopted sharing arrangement, different levels of sharing can be achieved. On the other hand, based on the resource based view, resource sharing can lead to the loss of a source of sustained competitive advantage for the network operator i.e. infrastructure. In this study (part of the SAPHYRE project), the notion of infrastructure sharing is made clear and the most important drivers, barriers and trade-offs considered by the network operators before deciding to share infrastructure are investigated. By doing so, the most important considerations that affect the final choices of the network operators regarding infrastructure sharing are made explicit.

TL;DR: In this article, the authors reviewed the key policy processes, instruments, and governance structures in the telecom and broadcasting sector in India and highlighted new regulatory processes and instruments that could be adopted from the telecom sector to facilitate the emergence of totally new business models whose adoption could lead to commercially viable service for the low income segment as well.
Abstract: Telecom sector is seen as a driver of economic growth, especially in developing countries. Recent trends across various countries, including developing ones show that the social and economic benefits of telecom services, especially mobiles are significant, including for the low income segment. Various studies and field experiences suggest that even the most poor have significant information and communication needs and, therefore, national development programs typically incorporate ICT components in their development agenda. Both telecom and broadcast sector have an important role to play in this endeavor. While telecom sector has been able to play a significant part in this area, broadcasting sector has fallen behind in its ability to deliver.There has been a revolution in both telecom and broadcast technologies resulting in low cost service delivery, increase in variety of platforms, and media. As a consequence of technological convergence, it is possible to apply the telecom policy best practices and principles of regulation to the broadcasting sector to achieve growth. But, while the world over, telecom sector has undergone significant regulatory changes, reform processes in the broadcast sector have been slower. This has precluded or reduced the benefits of broadcasting for development. While the Indian government had focused on telecom policies resulting in rapid deployment, a similar level of initiatives in the broadcasting infrastructure side was missing. With the recent developments in telecom and broadcasting technologies, leading to a drop in prices of radios, cheaper availability of mobile phones that have FM receivers integrated and rapid uptake of mobile telephones, government policies should focus on facilitating growth of broadcasting infrastructure, especially FM. For example, the emergence of mobile TV and growth in IPTV are contingent upon several key reform initiatives. Recognizing these linkages, the Indian government introduced the Communication Convergence Bill in 2000. However, it was not passed.To spur growth in telecom, the government had taken innovative policy initiatives such as revenue sharing regime for licensing, identification of viable parameters for commercial operations and brought about institutional change leading to rapid growth. Despite their potential to trigger growth in the broadcasting sector, policy innovations in the telecom sector have not been transferred to the broadcasting sector.The paper examines key policy processes, instruments, and governance structures in the telecom and broadcasting sector in India. The paper is based on the author’s experience as a member of some key national committees and secondary research. The paper reviews the innovations in the telecom sector in India and other countries and in the broadcasting sector in other countries. It then builds on prior work in the literature to draw the implications for policy making processes and structures for the converged sector and the consequent possible outcomes on availability of services. The paper highlights new regulatory processes and instruments that could be adopted from the telecom sector. Such initiatives could facilitate the emergence of totally new business models, whose adoption could lead to commercially viable service for the low income segment as well. Such developments would not only help government departments such as health and education to deploy the development agenda in a more meaningful way, but also help in the economic growth of the sector and the economy.

TL;DR: The Telecom Regulatory Authority of India (TRAI) was constituted in 1997 as an independent regulator in this sector and has become one of the fastest growing telecom markets in the world as mentioned in this paper.
Abstract: Telecommunications, being one of the prime support services is required not only for rapid growth, but also for the modernization of various sectors of the economy. It has become especially important in recent years because of enormous growth of Information Technology (IT) and its linkage to the other sectors. Long back, the telecom network in India was owned and managed by government as it is considered as a strategic service. During that time, the telecom industry had a monopoly. Liberalization made the Government to adopt a gradual approach for the telecom sector reforms. Through selective privatization, competition was managed in different segments of the telecom market. In 1992, India introduced private competition in value-added services followed by opening up of the cellular and basic services for local area to private competition. The Telecom Regulatory Authority of India (TRAI) was constituted in 1997 as an independent regulator in this sector. With an addition of more than 6 million connections per month, India has become one of the fastest growing telecom markets in the world. The expanding spectrum and enormous growth have made the cellular operations highly competitive. Although the network in rural areas is expanding, but still the rural areas are not adequately covered. India is the 4th largest telecom market in Asia after China, Japan and South Korea. India is the 5th largest telecom market in the world and 2nd largest among emerging economies of Asia. Contribution of telecom sector in terms of revenue is 2.1 percent of the GDP as compared to 2.8 percent in developed economies.

TL;DR: In this article, the authors trace the state's motivation to restructure telecom policy between India's independence and 1999, by which time the core objective of the telecom policy had become the availability of affordable and effective communications for citizens.
Abstract: The telecom sector has been an important actor in the Indian state's policies for 'development.' However, the nature of the linkage between telecom and development, as well as the role of the state in this process, have changed over time. How did Indian telecom policy, with its focus on telecom production for development and its dismissal of access to telecom as a luxury up until the 1980s, become an advocate for telecom access for development by the late 1990s? Using policy documents and an analysis of secondary literature, I trace the state's motivation to restructure telecom policy between India's independence and 1999, by which time the core objective of the telecom policy had become the "availability of affordable and effective communications for citizens." I argue that motivation alone is not enough to bring about policy change. Since the state had to negotiate with diverse interest groups both within and outside the state, and also maintain its own legitimacy, the state's motivation had to be backed with state capacity and political opportunity before it could restructure telecom policy. Pushing further at this framework of policy change, I suggest that motivation, capacity, and political opportunity are determined not just by material conditions but as crucially by ideological constructs and discourses.

TL;DR: In this paper, the authors present a snapshot of top 10 business risks faced by any industry sector and divide risks into four quadrants- strategic, compliance, operational, and financial threats.
Abstract: The Indian telecom industry is one of the fastest growing in the world. The rapidly evolving challenges and opportunities facing telecom companies domestically as well as globally are driving ongoing change in the industry's risk universe. As companies develop and implement their strategies to sustain and create value, they must ensure that their understanding and management of risk also keeps pace. This article brings about the current scenario of the Indian Telecom sector, the risk radar by Ernst and Young which presents a snapshot of top 10 business risks faced by any industry sector. This risk radar divides risks into four quadrants- strategic, compliance, operational, and financial threats. Companies should conduct an annual risk assessment in order to inculcate ways to mitigate, and manage risks.

TL;DR: In this article, the authors provide an overview of the most important studies and their key findings, addressing methodology and assessing total contributions of telecom infrastructure investment to GDP growth and employment in important economies in Europe, North America and other parts of the world.
Abstract: Telecommunications investment has been identified as one with a strong potential to spur economic growth and create employment. Investments in telecommunications infrastructure could not only provide a short-term boost to the economy, but also lay the groundwork for long-term improved growth and employment perspectives. Many fiscal stimulus programs adopted by national governments to lessen the impact of the recession and boost economic recovery include substantial stimulus investments related to digital infrastructure. Indeed research findings indicate that telecom investment has an impact far beyond the scope of the industry itself, promoting growth in adjacent industries and creating new industries. Telecommuni-cations investment explains up to one third of economic growth. With regard to employment, telecommunications investments have contrary effects: On the one hand, it is widely acknowledged telecom investments lead to significant productivity improvements. Increased efficiency is certainly beneficial for the economy; however, process optimization may lead to job losses. On the other hand, various direct and indirect employment effects can be identified that contribute to create new jobs. Therefore, the question arises whether negative or positive effects prevail. Our article gives an overview of the most important studies and their key findings, addressing methodology and assessing total contributions of telecom infrastructure investment to GDP growth and employment in important economies in Europe, North America and other parts of the world. We review ICT productivity studies, econometric studies analyzing the relationship between broadband infrastructure and economic development, and "forward looking" studies estimating the multiplier effects of telecom investments. Most evidence indicates a strong and robust positive relationship between telecom investment and both economic growth and employment. These results confirm that investments in digital infrastructure may significantly contribute to overcome the adverse effects of the economic crisis and improve long-term growth prospects.

TL;DR: In this paper, the authors developed a system for automatic voltage regulation at remote telecommunication sites with customized features, which automatically creates the industry to reduce their OPEX and CAPEX continually.
Abstract: The telecommunication industry in Sri Lanka is showing fast growth and expands services to their customers, especially during past decades, by increasing number of service providers with much competitive Tariffs. The main challenge of the service provider is to sustain with the competitive Tariff reductions and advancement of their services to customer doorstep demanding by the industry. Not like in other industry, the telecom customer is having the freedom to select any service provider by own decision without facing any monopoly or other influence by the industry. This automatically creates the industry to reduce their OPEX & CAPEX continually. The CAPEX is always increasing and the reduction possibility exists only with OPEX in the telecom industry. Electricity contributes to the major portion of OPEX of remote telecom site operations. The electricity by means of Diesel Generator (DG) operation or Commercial supply (CEB/ LECO) is always a difficult facility in remotely operated telecommunication base stations. This is due to the nature of the location of the selected site and the quality of the nearest/ rural commercial supply. Due to this, the site needs to run with the DG in most of the period of the day or face with service outages due to interruptions of the electricity with huge OPEX and unexpected losses in income. The main objective of this research project is to develop a system for automatic voltage regulation at remote telecommunication sites with customized features. The outcomes of this research will be a remarkable development in the telecom industry. We also supposed to share this knowledge with all the interesting parties to extend the benefits not only to the telecom service providers, but also to the customers by means of lowest tariffs.
