Abstract: A point-to-multipoint or two-way communications system is provided by a nodal transmitter located in a node with a plurality of nodal antennas radiating different polarization signals about the node. The system includes subscriber stations with directional antennas adapted to receive signals radiated from the nodal transmitter. The system may additionally include capability for transmitting and radiating subscriber signals to the nodal transmitter location for two-way communications.

Abstract: The invention provides methods and systems for power control in point-to-multipoint communications systems. Methods are described for both downstream and upstream control. Subscriber signals received at the base station 11 are level detected at receiver 77 and power adjust processing 79 and a control signal is sent to control output from the subscriber transmitter 65. The invention maximizes the signal-to-noise ratio and signal-to-interference ratio for subscribers (CPE) while minimizing transmitted power. The invention is ideal for use in local multipoint distribution service (LMDS) systems.

Abstract: A wireless communication system (100) is disclosed in which a central office (102) generates a signal. A first base station (104) receives the central office signal and transmits a first broadcast signal in a first frequency range in response to the central office signal. A second base station (124) receives the first broadcast signal and transmits a second broadcast signal in a second frequency range in response to the first broadcast signal. A third base station (134) receives the second broadcast signal and transmits a third broadcast signal in the first frequency range in response to the second broadcast signal. In accordance with the present invention, a plurality of base stations are each able to provide one-way or two-way communication to a plurality of customers (110, 130, 140), with only one base station (104) receiving signals directly from the central office (102).

Abstract: The invention provides methods and systems for power control in point-to-multipoint communications systems. Methods are described for downstream using an off-the-air monitor 31 and pick-up antenna 33. The monitor detects the power level of the pick-up signal and a control signal sets the transmittal output from the base station in proportion to the detected composite power level.
