Claims
- 1. 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.
- 2. 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.
- 3. 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.
- 4. An antenna arrangement as claimed in claim 3 wherein control and supervisory information received from the base station network includes information concerning signal frame structures, frequency values and beam power levels.
