The aim of this book is to provide 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:
Ø The design concepts associated with non-geostationary satellite systems
Ø (constellation, link budgets, Doppler, etc)
Ø 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, etc)
Ø Inter-working between satellite and terrestrial networks (network architecture, ATM Adaptation Layer)
Ø Radio interface technologies (WB-CDMA, TDMA, transmission environment)
Ø Regulatory issues
Ø Future services and applications
Ø Potential satellite markets (prediction techniques, effect of tariffing policies on potential market)
· This is one of the first books to cover the latest developments of network technology in mobile satellite services
· Provides in-depth analysis of market prediction methodology and evaluates potential satellite-UMTS markets
· Discusses ATM technology via satellite
· Describes future services and applications
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.
