Regulatory decisions have controlled the possible technical alternatives in the use of artificial satellites, for both domestic and international telecommunications, since the enactment by the US Congress of the Communications Satellite Act of 1962. At the same time, advancements in technology have caused satellite systems to play a larger role in telecommunications. An updating of the 1934 Communications Act would allow for a more definitive statement of national satellite policy and for a revised regulatory standard. This article reviews some of the principle factors which have influenced communications satellite policy, and offers additional issues for consideration that can affect the development of communications satellite markets, systems and services.  相似文献

A vision of improved telecommunications infrastructure leading to dramatic improvements in the economies and the quality of life in developing countries is now supported by an increasing body of evidence. Economic justification of the necessary investment depends on the availability of appropriate low cost technology, such as microprocessor-based digital satellite earth stations costing under $10000. Such technology is technically feasible, but its availability will depend on the emergence of a consensus among telecommunications lenders, borrowers and manufacturers that the benefits can be achieved and therefore the necessary mass market will emerge.  相似文献

Optical fibre technology can supply enormous bandwidth to meet the demands of the ever expanding telecommunications services. It has been said that they are the biggest competitors to satellites. This article outlines the history of optical fibres and how they work, and compares the benefits of both optical fibres and satellites for the communications market of the future. Geostationary satellites offer a global interconnectivity from both mobile and fixed points. Optical fibres offer heavy routing of both voice and data messages, freedom from interference, and cost advantages. The authors conclude that both will survive.  相似文献

Presents a method for estimating the impact on national development of installation of telecommunication facilities in rural areas of developing countries. A methodology developed by Hardy is applied to three groups of developing countries and a hypothetical rural region to estimate the impact on GDP per thin route satellite earth station installed over a ten year period. A logarithmic relationship between telephone density and impact on GDP per earth station is found, so that the impact per earth station increases with lower telephone densities. The model can be used to estimate the impact on national GDP of telephone installations and/or thin route earth stations in regions of low telephone density.  相似文献

The author discusses three interrelated facets of the problem and potentials of communication satellites for rural development. The first concerns the nature of the needs for rural telecommunications, and differences from urban telecommunications needs. The second facet is the technical and economic nature of satellites, compared to other technologies, as it relates to the task of meeting rural needs within rather severe economic constraints. Finally, a set of policy issues emerges from the review of technical and economic characteristics in the context of rural needs.  相似文献

This study estimates cost-based prices for wholesale voice and data services provided to 3G (WCDMA) MVNOs according to their distinct types. For estimation, 3G MVNOs are classified into different types, and the overall cost of WCDMA facilities are separated into voice and data components based on their subscriber rates, actual traffic rates, as well as efficiency consideration of traffic rates. The study then calculates cost-based wholesale prices of voice and data services for each of the 3G MVNO types. The result of this study shows that a cost-plus pricing scheme can help achieve the policy goals of the regulator, namely, lowering telecommunications tariffs and facilitating the introduction of new convergent-type services, far more effectively than the current retail-minus pricing scheme. The findings of this study may assist firms in developing business models based on 3G networks and telecom regulators in designing policies related to interconnection, mVoIP, prepaid calls, wholesale services, and network neutrality.  相似文献

The Independent Commission for World-Wide Telecommunications Development (Maitland Commission) reported that telecommunication networks, including public telephone systems, are an infrastructure which aids economic development throughout the world. The Commissions objective is to bring the majority of the world's population within easy access of a telephone and, in time, other communications services. Development in the Pacific Islands region is slowed by a lack of efficient communications. The islands are spread over 29 million square kilometers of ocean and extremely vulnerable to natural disasters. Pacific Island Nations (PINs) have problems of foreign exchange, skill shortages, and poor credit terms. Telecommunications infrastructure audits showed the overall regional teledensity of 3 telephones per 100 population. The individual countries vary form 8.3 in Fiji to 1.5 in Papua New Guinea and 25.2 in New Zealand. The population of the developing island countries is in mostly rural areas where there is a chronic shortage of telephones. The constraints on radio systems can be overcome with satellite technology. The new technologies are coming on the market faster than these countries can afford to handle them. By using satellite technology and sharing facilities PINs can greatly reduce the cost of telecommunications systems. Fiber optic cables will be used to carry large volumes of traffic over major routes while satellites can be used for a array of services for the smallest PIN nation to the largest route rim country. Work is being done to standardize the equipment specifications and to develop policies for the coordination of regional telecommunications training. To further facilitate communications development in this area, changes need to be made in international funding priorities for development, and recommendations by the Maitland Commission must be taken seriously.  相似文献

In the light of converging services for voice, data, and video, this paper discusses the challenges for telecommunications regulation from a European perspective. The Netherlands, a country with excellent conditions for facilities-based competition, is discussed as a case in point. With dynamic issues at the heart of the debate, the role of regulation and government intervention more generally is to create and possibly to sustain conditions among operators to upgrade their networks and to provide innovative services. A fresh look at current regulation suggests that an overhaul may be needed.  相似文献

Beginning with the historical role and importance of multi-physical standards in wireless telecommunications for the future in the US, Japan and Europe, this paper provides a cohesive vision of how wireless communication, voice over Internet protocol (VoIP) is likely to develop. Also covered in this paper are its benefits, the technical and regulatory support required to realize this vision and an assessment of its potential impact on the structure of the telecommunications industry. Although the competitive structure of the Internet is relatively open, several factors, such as frequency allocation policy and radio interface standards, could block the efficient evolution of wireless services to an IP platform. The paper proposes two major technical requirements to enable effective competition in wireless VoIP and achieve greater technical productivity.  相似文献

A ‘user perspective’ from F. Mingaye of Ford Motor Company Ltd. Ford is a large user of BPO telecommunications services, with a current emphasis on voice and telegraph. Like other large organizations, from time to time it develops special requirements to meet its business needs. Is the Post Office's exercise of its monopoly powers best suited in all respects to meet the needs of its customers? This article is an edited version of a paper presented at the conference on ‘Post Office telecommunications - the way ahead’, 25–26 September 1978, London, UK, organized by Information Studies Ltd, Chorleywood, Herts.  相似文献

A conference will open on 8 August 1985 under ITU auspices to consider major procedural changes in the international regulation of the use of the radio spectrum by geostationary satellites. There has been strong pressure for the introduction of a priori orbit/ spectrum planning for, for example, the fixed-satellite service from countries which foresee that they may lose their option to set up domestic satellite networks under the present ptocedure. However, reform of the present procedures, rather than radical change, would give better assurance that the real needs of all countries will be met.  相似文献

International telecommunications facilities—both satellite and cable circuits—in the Atlantic and Pacific Ocean basins are characterized by persistent excess capacity. Although some excess is desirable to provide flexibility and protection against system failure, the problem is so great that Intelsat has 100 satellite transponders deemed surplus to international requirements. However, plans are under way for continued expansion of cable and satellite capacity. This article examines why telecommunications organizations are investing in such a seemingly wasteful manner. Three possible explanations are explored: (a) over-optimistic traffic forecasts, (b) market structure and regulatory policy, and (c) inefficient pricing of circuits.  相似文献

The telecommunications world is being swept by technological and national regulatory changes. The international telecommunication institutions — the ITU, INTELSAT and CEPT — were founded in times when technological trends were more stable and national regulation was more homogeneous. How will they cope with these new changes? In an era of growing heterogeneity, the ITU may need to look increasingly beynd itself to maintain its centrality. Meanwhile, INTELSAT faces challenges from new market entrants and a more flexible approach to new technological and commercial imperatives in satellite and cable services. The EEC is awakening to the need for institutional change within Europe and this is already having an impact on CEPT. It is concluded that to survive and to maintain relevance the existing international institutions will need to initiate changes or face a loss of authority to other institutions such as OECD and EEC.  相似文献

Implementation of telecommunications infrastructure throughout developing countries is a prerequisite to national development. The fundamental question, argues Dr Parker, is how can developing countries pay for the capital investment in the necessary telecommunications equipment. The need is to encourage an institutional structure that can stimulate innovative, lower-cost appropriate rural telecommunications technologies without imposing excessive risks on the national telecommunications monopoly. With sucessful models to follow, it will be easier to achieve consensus between developing country borrowers, international lenders and telecommunications manufacturers.  相似文献

Within a few days of each other in early 2009, the national governments of Australia and New Zealand announced separate plans to invest heavily in advanced broadband networks. Taxpayers in each country will contribute at least half the estimated cost of fibre-to-the-premises networks reaching the overwhelming majority of households and businesses within 8–10 years. These complex and controversial forms of ‘public private interplay’ demonstrate three trends: a shift away from the liberalization and privatization policy consensus of the last two decades; shared convictions about the anticipated size of fast broadband’s economic and social benefits, and about the need for wholesale-only fixed line network operation to maximize those benefits; and the unlikely impact of the global financial and economic crisis in stimulating investment in particular infrastructures seen as critical to the national economies that emerge from it. This article discusses industry structures and regulation in Australia and New Zealand, their long history of public investment in telecommunications and the recent popularity of public private partnerships (PPPs) with Australian state governments. It outlines the ambitious broadband plans and surveys their prospects. Like so many other policy actions following the global economic crisis, these are distinctively national responses to internationally shared challenges.  相似文献

When the telecommunications industry was liberalised in Europe and North America in the 1980s and 1990s, it inherited a legacy of monopoly providers whose footprint was national or multi-regional in its character. The regulatory framework, particularly that adopted in EU member states, reflected this pattern of relatively homogeneous deployment achieved, in part, by decades of cross-subsidised pricing and universal service goals. Perhaps because of this legacy, telecommunications regulators have often adopted the presumption that relevant markets are national in character, unless proven otherwise Although geographically-variegated regulatory remedies have been permitted (even in the face of allegedly national relevant markets) and adopted in many member states, many regulators have never done so, and overly cautious thresholds for permitting geographically based forbearance suggest a continued bias towards presuming national markets and remedies. We find that this presumption of uniformity and the tendency to aggregate geographic markets together is not supported by first principles of antitrust analysis, although there may have been strong practical reasons to apply this presumption in the past circumstances of the telecommunications and broadband industries.On the ground, however, there has arguably never been as much heterogeneity across geographies and across technological solutions that provide effective ultra-fast broadband speeds. Both technological (i.e., product market) and geographic heterogeneity are likely to increase with the advent of mobile 5G networks. With their deployment, a cautious regulatory stance towards geographic variation and a cautious regulatory stance towards inter-technology or inter-modal competition may result in regulation that could exceed what is required to ensure effective competition and could instead distort the incentives to enter of facilities-based actors. This may also result in higher-cost and inefficient investment. A more geographically varied and technologically agnostic regulatory framework may satisfy the principle of proportionate and focused regulation—with the possibility that the locus of regulation shifts from the access network to bottleneck facilities such as fibre, ducts and poles.This discussion is especially germane when one considers the highly speculative nature of forecasts and projections about future demand, and the competing claims of proponents of 5G and fibre. While there is some scepticism about the performance of mobile networks, we note that pure mobile and fixed 5G services may have synergies in deployment, and that the idea of competing with residential broadband services is a core strategy of very influential large-scale industry actors. In terms of a future research agenda, regulatory decisions could benefit from much more research into the relationship between domestic and global bandwidth constraints and their influence on development of software and application, as well as much more quantitative research by academics on the drivers of bandwidth demand. The risks associated with promoting investment that results in large-scale wasted resources should also be central to the regulatory agenda.  相似文献

Operators of telecommunications networks, network systems manufacturers and policy markers have placed their hopes on ISDN for a stable and brilliant telecommunications future. However, non-voice service providers, customer premises equipment manufacturers and large users fear that the envisaged network approach will not serve their future requirements. Telecommunications networks will have a strategic importance in national economic development. It is important not to constrain that development by tying them to an inappropriate and inflexible network structure. In this article the uncertainties of the ISDN network are reviewed, questions are raised and the evolution of the network is examined, from the perspective of the actors involved in the sector: large users, equipment manufacturers, policy makers and service providers.  相似文献

This paper analyses the problems faced by developing countries in extending telecommunications to remote and rural areas. It identifies some possible technical solutions using mobile satellite services, especially in specialized niche markets, but also ways in which telecommunications can be made more widely available to populations in rural and remote areas. Although means must be found to finance such development, the paper highlights the necessity of implementing policy and regulatory frameworks conducive to the availability of mobile satellite services.  相似文献
