  • Patent number: 6560441
    Abstract: A solution for providing an improved fading margin environment for in-building wireless coverage. An optical fiber or other available broadband signal distribution network is used to distribute signals between centrally located base transceiver station (BTS) equipment and remotely located transceiver equipment referred to herein as a cable microcell integrator (CMI). The CMIs are deployed in a configuration to provide radio frequency coverage in a desired microcell area such as a building floor. In a preferred embodiment, a leaky coaxial cable is used as a radiating element within the microcell.

  • Patent number: 6480702
    Abstract: An apparatus and method for transmitting telecommunications signals from a wired system to mobile receivers, includes a signal hub for receiving a telecommunications transmission signal for distribution to a mobile receiver and including first elements for measuring a power level of the received transmission signal, a multiplicity of distributed remote antenna drivers, each having a respective antenna, a controllable amplifier adapted to couple transmission signals to the antenna and second elements for measuring a signal power level of a transmission signal at the antenna, a network for coupling the transmission signal from the signal hub to one or more remote antenna drivers, and elements for determining a gain factor for each respective amplifier and thereby the transmission signal at each respective antenna in response to the measured received signal power level and the respective measured antenna signal power level.

  • Patent number: 6415132
    Abstract: A technique for controlling a wireless communication network to provide for blossoming capacity to a relatively high capacity state and/or wilting capacity to a relatively lower capacity state. Connections in progress with active subscriber units are properly handled without the need to send explicit handoff commands from the base stations. The cell sites may be advantageously implemented with cable microcell integrators that comprise remotely deployed transceiving equipment that are interconnected to centrally located base transceiver station equipment via a broadband cable distribution network. In an initial relatively low capacity state, adjacent cells are operated at the same carrier frequency such that they form simulcast groups so that subscriber units traveling in adjacent cells will operate with the same radio channel. As demand increases, the power level of an auxiliary radio transceiver is gradually increased while the power level of the original transceiver in the cell is gradually decreased.

  • Patent number: 6349200
    Abstract: A monitoring and command system for use in a wireless communications system including remotely located transceivers for transmitting and receiving telephony signals to and from wireless telephones wherein each of the remote transceivers is connected to a broadband distribution network. A central location includes remote antenna signal processors connected to the broadband distribution network and a control unit is connected to the remote antenna signal processor, and the monitoring and command system controls operations of the remote antenna signal processors and the remote transceivers. The control unit exchanges control and monitoring messages with the remote antenna signal processors, and each exchange of messages comprises a completed exchange of messages with one remote antenna signal processor before initiation of an exchange of messages with another remote antenna signal processor.

  • Patent number: 6192216
    Abstract: Circuitry in central and remote transceivers is disclosed to monitor wireless telephone signal levels and control the settings of gain control circuitry in a plurality of remote transceivers that carry telephony signals between wireless telephones and the central transceiver via a broadband distribution network so that the central transceiver receives telephony signals from all remote transceivers within a given range of signal amplitude.

  • Patent number: 6122529
    Abstract: Apparatus and a method are disclosed for a wireless telephony system to eliminate blind areas where signal coverage is weak or non-existent by providing remote transceivers that are physically located in the blind areas. A central transceiver located with a base telephone station and tower mounted antenna receives wireless telephony signals being transmitted by the antenna to a wireless telephone and forwards it over either an dedicated or existing broadband distribution network, such as a cable television distribution network, to the remote transceiver which transmits the same telephony signals in the blind area to a wireless telephone operating in the blind area. Telephony signals originating from a wireless telephone operating in the blind area are received by the remote transceiver and forwarded over either the dedicated or existing broadband distribution network to the central transceiver which inputs the telephony signals to the base telephone station.
