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.

Klappentext
Until very recently, geostationary satellites have been used as a sole basis for the provision of mobile satellite services. However, the launch of satellite personal communication services (S-PCS), which make use of non-geostationary satellites, has provided a new dimension to the mobile satellite communications industry. The introduction of S-PCS comes at a time when the global mobile market is experiencing phenomenal growth. This is set to continue with the introduction of 3G, including UMTS (Universal Mobile Telecommunications System), which will provide mobile multimedia services, similar to those available on personal computers.
Mobile Satellite Communication Networks aims to present the underlying concepts of mobile satellite technology and the technological and market drivers of UMTS in which terrestrial and satellite systems will provide complementary services.
* Explains the formal design methodology that is used to integrate communication networks
* Demonstrates how network-signalling protocols are developed in the future mobile network environment
* Describes the design of satellite constellations for global coverage
* Features a techno-economic analysis of the satellite market and how the roll-out of terrestrial mobile systems affects the take-up and development of S-PCN services
* Examines the latest research initiatives such as special features of higher frequency, multimedia satellite applications, mobile IP, fixed/mobile convergence and the use of stratospheric (airships) platforms to deliver multimedia services
By presenting the latest developments in mobile network technology, this informative text will prove indispensable to satellite, systems and networks engineers as well as senior undergraduate and postgraduate students. It will also be an essential reference for individuals working for mobile service providers and technical analysts.
