This book of proceedings contains papers for the Second European Workshop on Mobile/Personal Satcoms (EMPS '96), held in Rome, Italy, and hosted by the Consiglio Nazionale delle Ricerche. The EMPS '96 workshop follows the edition of two years ago, and is intended as an occasion for exchange of information and opinions among experts in the fast-growing field of mobile satellite communications. With respect to the first successful edition we only made one main modification. We issued a formal call for papers, instead oflimiting the selection process to invited papers as was in the past: 60 papers were received from 18 countries. Each paper has been reviewed by at least two referees, and then 41 papers were selected by the Workshop Steering Committee (WSC). An invited introductory lecture opens the workshop and is given by Dr. Andrew J. Viterbi, who is also honorary chairman of EMPS '96. Satellite Personal Communications Networks (SPCNs) are now expected to grow very fast, even beyond the most optimistic forecast: their unique feature to establish ex abrupto a world-wide communication fabric is certainly the winning card. Market analyses now indicate that LEO networks already planned to be operational around 1998 even risk being overwhelmed by users request, so that their extensions are already being considered. And, additionally, multimedia SPCNs are also being introduced at higher frequencies to provide broadband services.

Satellite personal communications were expected to form a very successful market, reaching many millions of customers. The market functioned, it has been, however, a big business failure. The book examines the rise and fall of the Satellite Personal Communication Systems (SPCS) from an interdisciplinary approach. It describes the technology of a market formed on the basis of heavy investment, which traded international personal communication capacity through the use of mobile satellite networks. Moreover, it analyses the main actors and their business strategies that have lead pioneers to failure. In addition, it focuses on the regulatory efforts, which proved unsuccessful in saving the market from collapsing. The analysis, based on the interaction of various parameters (technology, law, actors and market) forms an interesting level-playing field.

It is universally recognized that mobile and personal communications will play a significant role in the future telecommunications market. Research in this area is currently being undertaken in industry, public administration and research institutions, in Europe, the USA and Japan. The main emphasis of these activities is towards the definition of 3rd and 4th generation systems for mobile and personal communications for use at the beginning of the next century. These systems are intended to realise the true meaning of personal mobile radio communication i.e. allowing people to communicate freely with each other from homes or offices, cities or rural areas, fixed locations or moving vehicles. The satellite component of these future systems offers in particular an effective means of providing services to underdeveloped areas (e.g. Central and Eastern Europe). The book contains articles from leading researchers from international institutions and industries. It includes also the latest research results obtained by the two COST Actions. This is a major contribution to determining mobile and personal communications of future generation systems.

A Local Area Network (LAN) is a network usually within a single office or building that links desktop computers with each other and with peripherals such as servers and printers. The interconnect is the electrical and functional association of two different services, often provided by different suppliers, and it is from LAN inter-connection that telecoms operators seek to profit. The application of LAN interconnection via satellite can be used to complement and extend existing terrestrial public access networks through interconnection of clusters of broadband islands (such as LANs and MANs) in remote regions, where terrestrial lines are expensive to install and operate. Examples include: * Hospitals/clinics in remote and rural areas can be connected to the central hospitals in a tele-medicine environment * Remote offices can be connected to the central office to facilitate tele-working * University/colleges can be inter-connected to provide tele-education facilities Similarly, the possibility to provide access to such facilities in developing regions of the world is also viable and particularly attractive in the short to mid-term. Private LAN connection facilities could also be made available to the corporate user, offering the possibility to establish broadband internet access within a closed user group. Such a scenario could be of interest to the financial sector. By gathering the knowledge and experiences of well-known satellite systems experts from different parts of Europe this comprehensive volume provides detailed analysis on technical aspects for interconnecting local area network using satellite. Starting from traffic source modelling for different types of applications and services to different types of transmission techniques and networking functions for supporting such services, different case studies are presented to analyse the performance of such technologies. By providing an insight to current and future developments in satellite communications systems and by covering a broad range of materials in technical aspects in relation to satellite communication systems technologies, this volume will be of tremendous use to researchers, academia and industry. * First book to present such a thorough description of the reliability functions of satellite systems * Discusses IP over satellite * Provides a unique analysis and description of different simulation tools that are under development for evaluating the performance of satellite systems * Includes a chapter devoted to traffic modelling for satellite systems * Reviews current research and developments in security and discusses how such security functions can be implemented over satellite networks * Addresses different types of routing strategies and includes three different case studies which have been carried out to analyse the performance of different routing strategies
