  • Patent number: 9332463
    Abstract: Determining a geographic location of a cellular base station is disclosed. In some embodiments, a set of measurement data that includes for each of a plurality of signals received at the base station a corresponding measurement data is determined. The set of measurement data is used to determine the geographic location of the base station. In some embodiments, a set of measurement data is received. The received measurement data includes for each of a plurality of location measurement units at which a signal transmitted by the base station is received a corresponding measurement data associated with the signal. The set of measurement data is used to determine the geographic location of the base station.

  • Patent number: 8744466
    Abstract: Using radio frequency sensing to manage a mobile network resource is disclosed. A radio frequency environment is sensed to detect one or more base transceiver stations. A resource assignment, such as a frequency or channel assignment, is determined based at least in part on the sensed radio frequency environment.

  • Patent number: 8280366
    Abstract: Using radio frequency sensing to detecting that a cellular base station has been moved to a new geographic location is disclosed. A determination is made that a sensed radio frequency environment does not match a stored baseline. It is concluded, based at least in part on the determination that a sensed radio frequency environment does not match a stored baseline, that the cellular base station has been moved.

  • Patent number: 8155680
    Abstract: Providing a frequency reference to a mobile telecommunications base station is disclosed. A radio frequency signal that includes a periodic component having a known frequency is received. A frequency reference is derived from the received radio signal, based at least in part on the periodic component. The frequency reference is used to transmit from the base station at an assigned frequency.

  • Patent number: 7151740
    Abstract: An open loop power control system for an orthogonal frequency division modulation (OFDM)-based fixed/mobile wireless system. A preferred system and method comprise measuring signal strength of received interference-free pilot tones transmitted by a base station; determining pathloss according to received power level of pilot tones; and controlling transmit power level of the remote unit by adjusting transmitting channel attenuation according to the pathloss determined in the preceding step. The method may further comprise monitoring at the base station the received signal level of uplink pilot tones; checking if received signal level of uplink pilot tones is outside pre-set limits around the target level at the start of each call; and sending a command to the mobile station over the broadcast channel to increase or decrease the transmitting power level.
