  • Patent number: 8433315
    Abstract: Telephone apparatus, including a cable television (CATV) network interface, which is adapted to be connected to a CATV network so as to receive downstream cellular telephone communication signals transmitted at a downstream intermediate frequency (IF) via the CATV network from a base-station transceiver system (BTS) operative in a cellular telephone network. The apparatus includes a telephone interface, which is adapted to connect to a cellular telephone operative in the cellular telephone network via a physical connection. The apparatus also includes signal conversion circuitry, which is adapted to convert the downstream communication signals received at the downstream IF via the CATV network interface to downstream radio-frequency (RF) cellular telephone signals compatible with the cellular telephone network, and to convey the downstream RF cellular telephone signals to the cellular telephone via the physical connection.

  • Patent number: 7826802
    Abstract: A method for estimating a size of reverse link resources provided by a base-station transceiver system (BTS), including performing respective first, second, and third measurements of first, second, and third signal strengths received at the BTS. The method also includes comparing the first measurement with the second measurement so as to determine an initial minimum signal strength, and adding at a predetermined time an aging value to the initial minimum signal strength so as to form an updated minimum signal strength. The method further includes forming a comparison between the updated minimum signal strength and the third measurement, determining from the comparison a minimum of the updated minimum signal strength and the third measurement to be a minimum received signal strength, and determining the size of the reverse link resources provided by the BTS in response to the minimum received signal strength.

  • Patent number: 7711070
    Abstract: A method and apparatus improve the design and control of amplification stages in a radio frequency (RF) transmitter, so as to reduce its power consumption. In some aspects, the transmitter is operable to transmit an output RF signal at a target power level, which may vary over a wide dynamic range. For each target power level in the dynamic range, a control module in the transmitter configures operational settings of amplification stages of the transmitter in order to produce the output RF signal having the appropriate target power level, while consuming minimal power from the power source.
