Gain reductions due to scatter on wireless paths with directional antennas

The use of a directional terminal antenna on a wireless link can enhance received power by as much as the antenna gain. In local scattering, however, the enhancement will be smaller. We call this decrement the gain reduction factor, /spl Delta/. We present a statistical model of /spl Delta/ for fixe...

Zusammenfassung:The use of a directional terminal antenna on a wireless link can enhance received power by as much as the antenna gain. In local scattering, however, the enhancement will be smaller. We call this decrement the gain reduction factor, /spl Delta/. We present a statistical model of /spl Delta/ for fixed suburban paths at 1.9 GHz, based on angle-of-arrival measurements in New Jersey. Our results address the influences of antenna height, antenna beamwidth, distance and season.
