Claim:
1. A method for bandwidth allocation in a wireless communication system, the method comprising: anointing a base station, from a plurality of base station serving a service area, as a hand-off base station, wherein the service area comprises at least two cells and is allocated a bandwidth to service wireless devices in the service area, wherein one of the at least two cells comprises a first base station of the plurality of base stations, the first base station configured to service wireless devices in a first portion of the service area using a first portion of the allocated bandwidth, and wherein second of the at least two cells comprises a second base station of the plurality of base stations, the second base station configured to service the wireless devices in a second portion of the service area using a second portion of the allocated bandwidth, wherein anointing the base station from the plurality of base station serving a service area as the hand-off base station comprises anointing the first base station serving one of the at least two cells as the hand-off base station, wherein each of the at least two cells comprises an array of at least six directional sector antennas, wherein the at least six directional sector antennas are configured to radiate into a sub-portion of the cell at sixty-degree arc comprising a sector, wherein the sector has its own dedicated frequency assigned from the first portion of the allocated bandwidth; assigning a third portion of the allocated bandwidth as a hand-off frequency to the hand-off base station (HBS), wherein the HBS is configured to hand-off a subscriber between the at least two cells located in the service area wherein the hand-off is triggered when a received signal strength at the dedicated serving base station or at the hand-off base station is below an acceptable value, wherein assigning the third portion of the allocated bandwidth comprises assigning the third portion comprising a hand-off frequency to the first base station; and controlling signal transmission strength of the plurality of base stations, wherein controlling the signal transmission strength comprises:
