Claim:
A wide area communication network comprising: at least two hub sites, said hub sites being interconnected by a communication backbone, each said hub site providing coverage in at least one sector; at least two remote sites corresponding to each of said sectors; and a point-to-multi point broadband wireless system, said at least two remote sites being coupled to a corresponding hub site through said point-to-multi point broadband wireless system, wherein said point-to-multi point broadband wireless system at each said hub site comprises: a first radio unit operating on a first selectable frequency and providing coverage in a first sector; a second radio unit operating on a second selectable frequency and providing coverage in a second sector, said second sector being substantially adjacent to said first sector; and means for frequency selecting said first selectable frequency and said second selectable frequency from a plurality of available frequencies such that said first and second selectable frequencies are substantially separated thereby minimizing co-channel interference.
