Co-located omnidirectional and sectorized base station
First Claim
1. A cell site base station configuration for a wireless communication system, the base station configuration comprising:
- a sectorized base station including a sectorized antenna system providing sectorized coverage for a cell;
an omnidirectional base station coupled to and co-located with said sectorized base station, said omnidirectional base station including an omnidirectional antenna providing omnidirectional coverage for the cell;
a plurality of reserve channels supported and held in reserve by said omnidirectional base station; and
a controller for preferentially maintaining communication link assignments between subscriber units and said sectorized base station by temporarily reassigning a disadvantaged subscriber unit affected by an adverse condition from said sectorized base station to a selected reserve channel of said omnidirectional base station, and reassigning said disadvantaged subscriber unit to said sectorized base station when said adverse condition abates, thereby freeing said selected reserve channel.

Abstract
A preferred embodiment of the present invention provides a cell site base station configuration for a wireless communications system that makes use of a sectorized base station co-located with an omnidirectional base station. The sectorized base station has a sectorized antenna system and the omnidirectional base station has an omnidirectional antenna. The configuration may also include a controller that monitors the base station for communications links subject to adverse conditions and reassigns any such links to the omnidirectional base station. The adverse conditions monitored for may include multiple fade, equipment failure and a lack of available channels. The controller may also monitor the omnidirectional base station for links that can be moved to the sectorized base station and reassign any such links to the sectorized base station. The configuration may also include a network that interconnects the sectorized base station, the omnidirectional base station and the controller.
