  • Patent number: 6023621
    Abstract: In a wireless communication system in which plural base stations communicate with plural mobile stations using a control slot and plural voice (or data) slots, the present invention dynamically allocates which of a predetermined set of frequencies are used by a given base station at a given time. The base stations monitor the predetermined set of frequencies to determine which frequencies are being used within which slots within the range of radio reception of the base station. Currently unused frequency/slot combinations are assigned by a base station to service the next request for a voice slot.

  • Patent number: 6023460
    Abstract: In a wireless communication system in which a base station communicates with plural mobile stations using a control channel and plural voice (or data) channels, the present invention uses the control channel as a voice channel whenever the other voice channels are in use and a request is received from a mobile station for another voice channel. The base station's use of the control channel varies as the control channel switches from a control channel to a voice channel and back to a control channel again.

  • Patent number: 5943618
    Abstract: A wireless PBX system utilizes base stations dispersed throughout an area to be served with wireless telephone service. The base stations utilize multiple antennae to reduce problems associated with fading and multipath. In the present invention, the antennae of a base station or similar apparatus are rotatable, at least in pairs, so that the base station may be hung vertically, horizontally, or at some other angle to the horizon and the antennae may be readily oriented to a position which provides for preferred propagation characteristics for the antennae for the local area in which the base station is mounted.
