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.
