  • Method and system for assignment of fixed subscriber units in wireless local loop systems
    Patent number: 6701152
    Abstract: Method of assigning a fixed subscriber unit (FSU) to communicate with a particular base station and a system including a plurality of wireless FSUs. The system includes a plurality of base stations, which are coupled to a telecommunications network. Each FSU is coupled to a subscriber communication device, and each FSU is configured to communicate wirelessly with at least a base station. The FSU measures signal strength of a set of base stations. The FSU sends a message with the measured signal strength of the set of base stations to a base station. Circuitry coupled to the base station determines at least a base station to which the FSU is to be assigned based on the message and additional information in the circuitry coupled to the base station. In response to the determining by the circuitry coupled to the base station, the base station sends to the FSU a message including the base station to which the FSU is to be assigned.
