Abstract: ANTENNA BEAM BOUNDARY DETECTOR FOR PRELIMINARY HANDOFF DETERMINATION An antenna beam boundary detector for a sectorized cellular system is disclosed. The difference in signal level received by a main directional antenna and a broad beamwidth antenna is determined by detecting a modulator signal locally impressed on the signal received by the broad beamwith antenna. The signal level difference factor is the directional antenna beam boundary when the two antennas are correlated. Interferometer effects are cancelled by detecting both amplitude and phase modulation of the locally impressed modulation.

Abstract: AN ANTENNA ARRAY FOR A CELLULAR RF COMMUNICATIONS SYSTEM An array of antennas for a cellular RF communications system for providing communications to randomly placed transceivers in a given area. The antenna array includes a plurality of antenna sites located in the centers of cells. Each antenna site has a plurality of sectored antennas for providing sectored illumination outwardly for providing a plurality of communication channels. A predetermined number of sites are used to constitute a subarray of cells to provide a set of communication channels and channel allocations are repeated from subarray to subarray. Channels are also so allocated as to minimize channel interference and optimize channel utilization. An omnidirectional antenna may be provided for each antenna site for signalling purposes.
