  • Patent number: 5724665
    Abstract: An intelligent wireless communication base station provides communication between individual base stations over an RF radio channel. A control unit in each base station utilizes this communication to facilitate each base station to gather system data regarding the system arrangement of nearby base stations and to facilitate handovers of mobile wireless personal communicators from one base station to a another base station. This control unit is under stored program control and gathers information concerning set up channels of nearby radio ports, a developed list or table of neighbor base stations and signal strength values of nearby channels. Voice channels may be bridged allowing two personal communicators to communicate with each other through a single base station.

  • Patent number: 5528597
    Abstract: An apparatus and method synchronizes a communication frame of a newly added base station, in a Time Division Multiple Access (TDMA) communication network, to communication frames in the existing communication network of base stations by operating the newly added base station to receive down link signals of a neighboring active base station and synchronize its receive slot in the communication frame with a corresponding forward time slot of the communication frame of that base station. The receive time slot of the newly added base station is shifted by an offset reference time to establish it own forward time slot. The offset reference time is determined by the time interval required for the base station to change from a forward to a reverse channel.
