Multibeam Antenna Serves Broadband Wireless Corns

摘要

Multibeam antennas canrnprovide increased wire-rnless communicationsrncapacity with enhancedrnhigher Quality of service. One approach to designing such anrnantenna involves the use of space division multiple access (SDMA) techniques. SDMA methods provide high user capacity in a limited frequency spectrum without any major technological changes.rnSDMA techniques, whichrnare implemented by most wireless service providers for op-rntimum utilization of available spectrum, is typically restricted to three sectors in a 360-deg. coverage area. But using a multi-beam antenna system, the number of sectors covered can be increased to as many as 48. Because the system's beamforming network can reuse available frequencies and mitigate interference, it can result in a greater number of subscribers with improved quality of service for a wireless network's service area.
