Capacity increase of a CDMA cellular system by using directional antennas on mobile stations

It is shown that the capacities of both the reverse link and the forward link of a code division multiple access (CDMA) cellular system are increased significantly by using a steerable directional antenna on a mobile station. The additional cost for a directional antenna must be taken into consideration for implementation. It is shown that the interference from signals originating beyond the first two cell rings is not negligible for both the reverse link and the forward link.<
