Abstract :
Switched beam smart antennas are shown to either increase the capacity or extend the radio coverage of cellular systems, by increasing the carrier-to-interference ratio. The trunking efficiency degradation caused by narrow beam sectoring can be recovered or even improved by using a variety of trunkpool techniques. One drawback of switched beam smart antennas is that uplink performance is not uniform over the entire cell area, and this presents a limiting factor on the achievable gains
