INTRODUCTION Welcome to the AMIC session describing Communications, Convergence and Development. I am delighted to be nere today to share my ideas on the very important topic "New Communications Technologies : Applications for Development" with you. The telecommunications marketplace is complex, dynamic and enormous. Worldwide annual spending on telecommunications product and services will reach a trillion dollars by year 2001 (Figure 1). The market potentially encompases every person an every computer on earth. Communications technology development has brought forward the introduction of various new and convenient services, including mixed services using a single terms mission lines. Technological advancements have opened new horizons and new opportunities which never been predicted before. The global communications network enables us to access, collect, process and deliver information from an office or a terminal to almost any place in the world. Indeed we are now part of the global connectivity, global mobility and global information society. Within this environment, a nation or a region with different stages of communication infrastructure can no longer progress or have a competitive advantage without the support of high-quality communications networks. Several systems which have played a very significant role in the improvement of communications services include satellite, optical fiber and switching systems. The improvement has also been supported by the advances in standardization and software development. The following paragraphs will discuss a number of important developments and trends in telecommunications. These include communications networks optical fiber, satellite technologv, ISDN, personal communication system (PCS), ATM and Broadband services, and factors influencing services development, services development challenges, and applications for development. l ATTENTION: The Singapore Copyright Act applies to the use of this document.

The expanded needs of the communications users will be fulfilled by the future networks through advances in key technologies such as inte grated electronics, fiber optic communications, artificiafintelligence and distributed processing. Advance of technology has also made it possible to introduce numerous enhancement of services on the embedded public telephone networks. The Integrated Services Digital Network (ISTJN) takes advantage of the digitizations of the voice network to provide integrated voice and data services. Newer technologies such as cellular mobile for both voice and data, V-sat, fiber optics and personal mobile satellite services have become widely available. These technologies have led to cheaper, smarter networks/terminals and more cost effective services. A range of choices and solutions can be found or tailor made to meet precisely defined communications needs or to solve communications problem. Optical Fiber Technology Technical development of optical fiber and associated digital transmission systems has been occuring rapidly over the last several years. Not only has the capacity of fiber been increased (Giga bit system, see Figure 2), but also the average distance between repeaters has" lengthened. Consequently, optical fiber can now be employed throughout the network. Installations of optical fiber in the international and the national cable network will bring great advantages to operators and business customers, particularly in providing huge capacity transmission medium, increasing the availability of network lines and in providing the building blocks for private networks. Several countries have already completed a fiber optic backbone network and have links to international fiber optic cables. Within the next five years or so, fiber will become the medium of choice for most international traffic and an increasing percentage of inter-city national traffic. For the Asia Pacific Region 5 Giga bits system will be ready for operation by 1995 - 1996. 2 ATTENTION: The Singapore Copyright Act applies to the use of this document. Nanyang Technological University Library Figure 2a : Progress of Longhaul Experiments Figure 2b : Advances in Microelectronics on Optical Amplifier Submarine Systems Integrated Circuits In order to exploit the full potential of fiber and to justify costwise the installation of fiber rather than copper in the local loop, the network operators will need to develop a new range of sophisticated-based services. The three key technologies of fiber optics, data compression and ATM switching promise a future in which bandwidth capacity is the underlying force. Not only dis tance sensitive tariffing^ but also volume-based tariffing will be redundant. For almost the first time, the network operators will no longer need to use tariff structures as a way of rationing network access, but instead will need to concentrate their resources on developing demand for new services with the availability of enormous capacity in fiber optic network, sophisticated services like ISDN, and ATM switch will require higher a bandwith could be implemented. Satellite Communications Whether capacity is concentrated in a few large spacecraft or spread among smaller platforms, the market for satellite communications continues to grow. Satellite payloads will become more efficient, using spot beams to illuminate centers of high-density traffic. The beams will be steerable, allowing them to be switchecT to any new high-traffic area to emerge during the fife of the satellite. The future development could be an extrapolation of the present spacecraft configurations that would lead to multiple payload of satellites, offering a wide diversity of serives, with mass in the range of 3000 to 5000 kg, launched by either the NASA Shuttle, ARIANE, Hughes or Delta. The present state of the art of 10 years' design lifetime would probably be extended to twelve years, or fifteen years. The above scenario is appealing as, eventhough the cost per spacecraft in creases with size, the specific cost (cost per kg, or better per channel-year) decreases with growing mass. Market studies indicate that beyond 1995 the demand for such satellite should be in order of about 20 to 40 per year. Previous generation of satellite use GSO technology, and currently there is a growing number of blueprints of global low-earth orbiting satellite system. Hundreds of satellites will come in with the advent of application of Global Mobile Satellite System. Not only with mobile communications be a matter for terestrial systems but also for satellite system. Along with mobile communications"^ global paging will also implement. The following is a list of mobile satellite project that are planned to be in operation (Table 1.) 3 ATTENTION: The Singapore Copyright Act applies to the use of this document.
