Abstract :
Results highlighting the capacity enhancement and service or range extension of a wireless communication network employing adaptive antenna technology are presented. The picocellular service area was modelled using ray tracing techniques, and it has been shown that the maximum RMS delay spread was reduced from >100 ns to <30 ns by employing a beamformer with an associated array capable of forming multiple 15° wide beams. In addition, a seven-fold increase in the overall spectrum efficiency was predicted
