High Bitrate Modem Architecture (WIND-FLEX) Wireless LAN: The MAC, the Scheduler and Their Performance

A novel Wireless Local Area Network (WLAN) currently developed in the WIND-FLEX project(Wireless Indoor Flexible High Bitrate Modem Architecture, European IST Programme, IST-1999-10025, EU Fifth Framework Program, and suitable for small-office/home-office environments is described and analysed. The access scheme is TDMA at data rates ranging from 64 Kbps to 100 Mbps over a 50 MHz channel at 17 GHz. Data rate adaptivity requires a feedback channel and ad-hoc procedures. In particular, the MAC (Medium Access Control) drives the physical layer on the basis of link measurements exchanged via a suitable interface. System performance is evaluated via computer simulations by considering different traffic sources and the efficiency of the proposed MAC can be appreciated in terms of the final throughput.
