Abstract

TDM-BASED FIXED WIRELESS LOOP SYSTEM A time-division-multiplexed fixed wireless loop system and methods therefor are disclosed. The system comprises a plurality of cells each having a base stat ion and a plurality of terminals. The base station includes a steerable and adjustable multibeam antenna for communicating with each of the terminals, which have fixed antennas. A cell controller associated with each base station allocates communic ation time slots so as to minimize mutual interference between base station/terminal l inks sharing the same time slot. Slot assignment is based on regional, periodically u pdated interference measurements that are stored in data bases.
