Abstract
In this paper we describe and specify the design of a radio interface and Data Link Layer for a wireless indoor multimedia communications system. A radio frequency link operating in the 2.4/5.8 GHz ISM-band is considered as the transmission medium, where the maximum data rate using 16-QAM modulation can be up to 26.8 Mbit/s. The general concept of the system, which is based on a decentralised, i.e. ad-hoc, topology is illustrated. The radio interface is based on a combination of TDMA and FDMA with single carrier modulation. The system supports variable rate transmission and is flexible, since it can provide stream and packet services. We discuss the Data Link Layer of the system, as well as some physical layer receiver issues (synchronisation, equalisation, and antenna diversity), as well as providing simulation results.
This work has been carried out within the research project Multimedia communications on Integrated Networks and Terminals (MINT, funded by the German Ministry of Education, Science, Research and Technology (BMBF).
