Mobile satellite services are set to change with the imminent launch of satellite personal communication services (S-PCS), through the use of non-geostationary satellites. This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. One of the first texts to cover this rapidly evolving field, this text provides the reader with an overview of mobile satellite systems, from their initial introduction (Inmarsat), current satellite-PCS (referring to such systems as Globalstar), through to Satellite-UMTS and an understanding of the following: * The design concepts associated with non-geostationary satellite systems (constellation, link budgets, Doppler) * The concepts of UMTS (network architecture, aims, in the context of IMT-2000) and the role foreseen for the satellite component (complementary to terrestrial network, network extension, global availability) * Inter-working between satellite and terrestrial networks (network architecture, ATM Adaptation Layer) * Radio interface technologies (WB-CDMA, TDMA, transmission environment) * Regulatory issues * Future services and applications * Potential satellite markets (prediction techniques, effect of tariffing policies on potential market) With leading edge information, this valuable resource will be indispensable to researchers, engineers, operators and market evaluators in satellite service industries and research institutions, as well as postgraduates and research students in the field.

The Universal Mobile Telecommunications System (UMTS) is currently being developed in Europe as a successor to second generation mobile systems. The UMTS will be designed to operate in a variety of transmission environments, with the aim of providing mobile broadband multimedia services of a quality equivalent to that of the fixed network. Targeted for operation within the first few years of the 21st century, the UMTS network architecture will consist of both terrestrial and space components. This thesis is concerned with the satellite component of UMTS (S-UMTS), concentrating on three key issues: the network architecture of the integrated space/terrestrial mobile network; the radio interface characteristics; and the development of a model to predict S-UMTS traffic on a global basis. Initially, based on the objectives of the S-UMTS, the satellite's role in the future integrated mobile network is established. The generic UMTS network architecture is then presented, followed by a description of the requirements of the S-UzMTS network entities. Having determined the S-UMTS architecture, a number of issues that influence the level of achievable space/terrestrial network integration, including coverage and handover, are considered, before concluding with a procedure for selecting the optimum integration scenario. The discussion on radio interface issues focuses on two important topics: the characterisation of the mobile-satellite channel; and the possible formats for the CDMA and TDMA S-UMTS multiple access schemes. Link budgets are subsequently derived for a range of S-UMTS services, satellite orbits and terminal types.....

The shift from network-oriented to user-oriented services in the 80s and early 90s has increased the penetration of satellite services into the user community. Parallel to this, worldwide interest has arisen in Personal Communication Services (PCS), where satellites play a crucial role in the provision of PCS all over the world. Satellite Personal Communication Networks (S-PCN) are extremely attractive because they can serve a significant sector of the rapidly growing cellular market. This publication presents market perspectives and technological aspects in relation to satellite mobile and personal communication services. Papers were written by some of the most acclaimed European specialists in PCS. They present basic concepts and the latest research results.

Broadband Satellite Communication Systems and the Challenges of Mobility is an essential reference for both academic and professional researchers in the field of telecommunications, computer networking and wireless networks. Recently the request of multimedia services has been rapidly increasing and satellite networks appear to be attractive for a fast service deployment and for extending the typical service area of terrestrial systems. In comparison with traditional wide area networks, a characteristic of satellite communication systems is their ability in broadcasting and multicasting multimedia information flows anywhere over the satellite coverage. The papers presented in this volume highlight key areas such as Satellite Network Architectures, Services and Applications; Mobile Satellite Systems and Services; and Hybrid Satellite and Terrestrial Networks. Mobility will inevitably be one of the main characteristics of future networks, terminals and applications and, thus, extending and integrating fixed network protocols and services to mobile systems represents one of the main issues of present networking. The secondary focus of this volume is on challenges of mobility, that is, on technologies, protocols and services for the support of seamless and nomadic user access to new classes of applications in person-to-person, device-to-device and device-to-person environments. The book comprises recent results of research and development in the following areas; Seamless mobility; Mobile ad hoc and sensor networks; Analysis, simulation and measurements of mobile and wireless systems; Integration and inter-working of wired and wireless networks; QoS in mobile and wireless networks; Future trends and issues concerning mobility. This state -of-the-art volume contains a collection of papers from two of the workshops of the 18th IFIP World Computer Congress, held August 22-27, 2004, in Toulouse, France: the Workshop on Broadband Satellite Communication Systems, and the Workshop on the Challenges of Mobility.

This new resource presents the emerging role of Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geostationary satellites (GSO) as a delivery option for backhaul and wide area rural and urban mobile broadband and fixed access. The book offers insight into recently established Non Terrestrial Network standards. Readers learn which bands will need to be supported in next generation 5G and satellite devices and networks and how the bands will be characterized. Channel spacing, guard bands, FDD or TDD, out of band emission limits, and in band performance requirements are discussed. The book discusses what interference issues will arise from new band allocations including co-shared allocations and how interference will be mitigated in and between next generation terrestrial and satellite 5G networks. Readers learn how modulation choices will affect co-existence issues. The book discusses the design, performance, cost, and test implications of integrating next generation satellite physical and MAC layers with Release 16 and 17 5G standards and explores how these emerging spectrum and standards map on to IOT and MTC use cases in specific vertical markets. Readers learn how new active and passive antennas in the K bands and V and W band (E band) impact the satellite link budget and satellite delivery cost economics.
