Abstract
Abstract An antenna for a base station comprising a plurality of antenna arrays (40; FIG. 6a) each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams formed by the arrays provide a coverage in azimuth wider than each array. Means are provided for communication with a base station network whereby communication link means (77; FIG. 5) are provided for communication with a base station network whereby, in addition to telecommunications message traffic passing through the antenna, control and supervisory information can be exchanged between the antenna and the base station network.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
A cellular radio communication base station antenna comprising: a plurality of layered antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams of the plurality of arrays provide a coverage in azimuth wider than each array and in which communication link means are provided for communication between the antenna arrays and a base station network whereby, in addition to telecommunications message traffic passing through the antenna, control and supervisory information can be exchanged between the antenna and the base station network.
Claim 2
Dependent Claim
94 words
A cellular radio communication base station antenna comprising: a plurality of layered antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams of the plurality of arrays provide a coverage in azimuth wider than each array and in which communication link means are provided for communication between the antenna arrays and a base station network whereby, in addition to telecommunications message traffic passing through the antenna, control and supervisory information can be exchanged between the antenna and the base station network.
Claim 3
Dependent Claim
31 words
An antenna arrangement as claimed in claim 1 wherein control and supervisory information received from the base station network includes information concerning signal frame structures, frequency values and beam power levels.
Claim 4
Dependent Claim
177 words
A cellular radio communication base station antenna comprising: A plurality of layered antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams of the plurality of arrays provide a coverage in azimuth wider than each array; azimuth 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; and control means for controlling the switch 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 overlapping beams; wherein communication link means are provided for data communication between the antenna arrays and a base station network whereby, in addition to telecommunications message traffic passing through the antenna, control and supervisory information can be exchanged between the antenna and the base station network.
Claim 5
Dependent Claim
177 words
A cellular radio communication base station antenna comprising: A plurality of layered antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams of the plurality of arrays provide a coverage in azimuth wider than each array; azimuth 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; and control means for controlling the switch 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 overlapping beams; wherein communication link means are provided for data communication between the antenna arrays and a base station network whereby, in addition to telecommunications message traffic passing through the antenna, control and supervisory information can be exchanged between the antenna and the base station network.
