ABSTRACT:
A cellular network includes a control station and a network of base stations installed one per cell with which one or more mobile stations can communicate as they roam through a cell. Redundantly deployed spare base stations are introduced along with the primary base station at a central area of each cell. The redundantly deployed spare base stations handle new calls when the associated primary base station is overloaded, participate in retransmission of data lost due to degraded channel conditions and congestion in the network, and assist in handoffs. Primary and spare satellite stations are deployed in regions marked by hills or valleys to augment the communicative capabilities of the primary and spare base stations.
