Class Information
Number: 370/334
Name: Multiplex communications > Communication over free space > Having a plurality of contiguous regions served by respective fixed stations > Channel assignment > Hand-off control > Based upon a particular signal quality measurement > Using multiple antennas at a station
Description: Subject wherein a station (usually a base station) uses a plurality of directional antennas for transmitting or receiving information, and wherein signals from another station (usually mobile) are received by two or more of the antennas and the hand-off is performed based upon signal quality measurements received on the two or more antennas.
