CAPACITY AND SERVICE EXTENSION FOR WIRELESS NETWORKS USING ADAPTIVE ANTENNAS

Results highlighting the capacity enhancement and service or range ext ension of a wireless communication network employing adaptive antenna technology are presented. The picocellular service area was modelled u sing ray tracing techniques, and it has been shown that the maximum RM S delay spread was reduced from > 100 ns to < 30 ns by employing a bea mformer with an associated array capable of forming multiple 15 degree s wide beams. In addition, a seven-fold increase in the overall spectr um efficiency was predicted.
