Abstract :
The use of narrow beam directional antennas in wireless messaging has the potential of improving the transmission quality, increasing base station capacity, and reducing the number of base stations needed to provide a service for portable radio users. Directional antenna beams increase the protection to cochannel interference. The performance of a three-sector, twelve beam antenna system is compared with an omnidirectional and a conventional three-sector antenna configuration via computer simulation
