Controlling of an antenna array with sectorised radiation pattern to improve signal quality for mobile stations on beam boudaries

摘要

The transmitter may includes an omnidirectional antenna an array of directional antennas transmitting strong signals in several narrow overlapping sectors (A-D). Over a period of time (t), the transmitted signal may be switched between the various antennas to transmit into the various sectors. Switching may follow a predetermined pattern or may be optimized to follow moving station.
