receive communications transmitted from a corresponding base station 102 over a backhaul link and can forward the communications to mobile communication devices 106 through antennas 114 likewise repeaters 104 can receive communications transmitted from mobile communication devices 106 and forward these communications to the corresponding base station 102 over the backhaul link through antennas 115 according to a preferred embodiment of the invention base station 102 can incorporate suitable hardware and software for implementing smart antenna processing such processing can permit a single frequency to be used for implementing multiple backhaul links between a base station 102 and multiple repeaters 104 or for improved frequency re use in a system of base stations making use of such smart antennas for implementing repeater backhaul links implementing multiple repeater backhaul links on the same rf frequencies either within a cell or among a group of cells can be highly advantageous as it increases the available bandwidth for ground link communications with mobile communication devices 106 smart antenna processing systems as described herein can include switched beam antenna systems adaptive antenna processing or any other system incorporating special processing techniques to focus antenna propagation patterns for reducing co channel or adjacent channel interference fig2 shows a base station 102 that incorporates a conventional switched beam antenna array 211 for communication with mobile units 106 and repeaters 104 the switched beam antenna array 211 comprises 16 antenna elements each having a 22 5 degree beamwidth so as to.
