  • Power control in point-to-multipoint systems
    Patent number: 6308080
    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.

  • Downstream power control in point-to-multipoint systems
    Patent number: 6253077
    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.
