Base station antenna arrangement
First Claim
1. A non-sectorized base station arrangement comprising:
- a plurality of antenna arrays, wherein each antenna array is capable of forming separate overlapping narrow beams in azimuth,a plurality of r.f. transceivers each for transmitting and receiving r.f. signals for one or more calls,switching matrix means, andcontrol means;
wherein the control means is operable to switch a particular transceiver through the switching matrix means to any array whereby r.f. call signals can be exchanged with a mobile station located in any area covered by the narrow beams with the same transceiver.

Abstract
A base station antenna arrangement comprising a plurality of antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the totality of beams formed by the arrays provides a substantially omni-directional coverage in azimuth, azimuth and elevation beamforming means for each array, a plurality of r.f. transceivers each for transmitting and receiving r.f. signals for one or more calls, switching matrix means for connecting each transceiver with one or other of the arrays via the beamforming means, control means for controlling the switching matrix means whereby a particular transceiver is connected to a particular array via the beamforming means to exchange r.f. signals with a remote station located in the area covered by one of the narrow beams.

9. A method of operating a non-sectorized base-station arrangement comprising a plurality of antenna arrays, wherein each antenna array is capable of forming separate overlapping narrow beams in azimuth, a plurality of r.f. transceivers each for transmitting and receiving r.f. signals for one or more calls, switching matrix means, and control means;
- wherein the control means is operable to switch a particular transceiver through the switching matrix means to any array whereby r.f. call signals can be exchanged with a mobile station located in any area covered by the narrow beams with the same transceiver;
the method comprising the following steps;for a given signal received from a mobile, determining the best beam to be selected on the uplink by measuring the quality of the received signal strength from the mobile; selecting the antenna which would provide the best beam for a given channel on the downlink; transmitting a signal from a transceiver, through a transmit switch matrix and through the selected antenna, to the mobile. - View Dependent Claims (10)
