IBMS/i modular broadband inhouse-communication system for computer networks and wireless multimedia applications

Aspects of a new system concept are described, including signalling, physical architecture, interfaces, OFDM modulation, access, scaleability, channel coding, and the direct beam line-of-sight and spot diffusing infrared interfaces. The concept covers the area from the public network to mobile multimedia terminals inside or outside buildings, and is based on the ATM principle. Local area networks and computer networks can be integrated, and the performance characteristics of telecommunications services and high-speed local area networks are combined with the flexibility and mobility of mobile radio services.
