Global Mobile Satellite Communications: For Maritime, Land and Aeronautical Applications

Under the third and fourth-generation IMT-2000 services, high-speed and large-capacity multimedia data and Internet will be delivered through the satellite and radio networks and a wide variety of network services such as global roaming will be provided at the same time. In such a way many solutions and protocols will be employed in terrestrial radio and telecommunication systems, including ISDN, IP, TCP, IP/ATM, and UBR/ABR broadband and Internet solutions and protocols. At all events, with its new advanced service menu, the IMT-2000 network is required to provide not only mobility management for individual terminals but also various service control functions. With capabilities such as Quality of Service (QoS), in which the desired communications quality is individually established for each communication session, the IP/ATM switching system provides for a sophisticated and economic network configuration.
Usage of different satellite fixed and mobile solutions has increased dramatically in past years. Along with that trend there has been an increasing demand for higher transmission rates. Hence, to cope with this demand, new technologies have emerged onto the radio and telecommunications stage. The IP/ATM over satellite is one fine example, which is creating waves in the global telecommunication world today and is ideal for a wide range of satellite applications, including data transfer, voice, imaging, full motion video and multimedias. Its characteristics include scalability, which make it ideal for the traffic demands of broadband multimedia expected on data networks of the future. Just as the Internet revolutionized worldwide communications,...
