Telecommunications development in Europe will not only be a basis for innovation and a key to competitiveness, but will also contribute to answering Europe's community needs. In the future, the telecommunications networks will be capable of instantly transporting and processing voice traffic, text and images between any locations, be they homes, offices or businesses, thanks to digitalisation techniques and electronic processing of information. These networks will therefore constitute the nervous system of the economy, and more generally of tomorrow's society. Advances in communications technologies and services represent a vital link between industry, the services sector and the market and in this context, mobile and personal communications are currently one of the most dynamic sectors of activity and growth in Europe and world-wide.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

The Future Public Land Mobile Telecommunication Systems, being defined in the ITU Forum and the Universal Mobile Telecommunication System, being defined in the ETSI, are referred to as third generation mobile systems. The satellite or satellite constellations will play a significant role in providing personal communication services on a global basis. Personal communications requirements are changing rapidly as our society becomes more mobile and the demand for near instantaneous communications and universal access increases. The second generation mobile systems are not able to meet the unending expectations of the subscribers in terms of the range of services, higher user information bit rates, support of video, quality of service etc. The aim of the PCS is to provide personalised voice, data, image, and video communication services that can be accessed regardless of the location, network and time. The PCS are a family of telecommunication services supporting personal, terminal and service mobility. To provide a PCS, one needs a network with the ability to route calls and services to the location where the subscribers actually are, not to the locations where the subscribers are registered. In addition, wherever the subscribers actually are, they should be able to access the same set of services as where they are registered. It means creating a virtual home environment concept, i.e. a system concept for service portability. Third generation mobile systems could be an effective means to help developing countries bridge the telecommunication gap.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

One of the main techniques to increase capacity is the utilization of microcells. However, as cells are reduced, handoff rates are increased. In this paper the influence of the handoff process in the channel holding time is studied. The channel holding time is defined as the time duration between the instant that a channel is occupied by a call and the time it is released by either the completion of the call or a handoff. It is shown by simulation that the channel holding time distribution can be fitted by an exponential distribution for signal strength based handoff algorithms.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

Wireless data networks together with their wired counterpart could be put to work to achieve access to health care services hitherto unavailable in a geographical area, and improve and extend the existing services. We argue that wireless data could be leveraged to achieve the required integration in various sectors of health. We also discuss the services that the information flow could open up, and the functions of personal digital assistants (PDAs) and laptops as mobile nodes in an integrated information network environment.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

The International Telecommunication Union (ITU) has already undertaken the task of defining Future Public Land Mobile Telecommunications Systems (FPLMTS) which will mostly cover standards for PCS. The ITU World Radio Conferences address frequency allocation and related technical and regulatory aspects. The efforts in different ITU fora are important not only to approve various technical and regulatory provisions to enable implementation of mobile and PCS to meet the immediate market requirements but also to ensure adequate flexibility in the systems to meet future technical and operational requirements including compatibility in multiple operator environments. Among the new technologies, non-GSO MSS satellite systems are designed to provide global personal communications by more efficient use of radio frequency spectrum and power and by also taking advantage of the characteristics of orbiting satellites. The WRC-95 conference concentrated on several frequency allocation and related issues pertaining to nonGSO mobile satellite services (MSS).","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.

These services have immense growth potential which can be gauged by the fact that the world-wide compound annual growth rate (CAGR) of cellular mobile services over the last decade has been 68.9% and the previous year alone has seen the global addition of 19 million subscribers to the mobile network as against an addition of 38 million subscribers to the fixed networks. It is expected that these services will prove to be popular in India also and would witness a high growth rate. The Indian Government is also aware of emerging mobile communication services through LEO, MEO and GSO satellites and has plans for their timely utilisation for the benefit of the Indian economy. With the gradual reduction of cost, utilisation of fixed wireless solution in the access technology has become attractive. A number of options are being considered. The main guiding factor for the choice of technology has been the careful study of the evolution of technologies and adopting the technology which will remain current for several years to come.","PeriodicalId":117877,"journal":{"name":"1996 IEEE International Conference on Personal Wireless Communications Proceedings and Exhibition.
