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.

Abstract: In a wireless microcell distribution system, a method is provided for embedding reference and control signals within the channel utilized for carrying the telephony signals, thereby eliminating roll off and cable tilt issues which are the result of providing the reference and control signals below the forward CATV band. The elimination of the signals below the forward CATV band also eliminates additional cable spectrum and installation difficulties which are the result of cable tilt in which frequency dependent amplitudes require compensation through the utilization of equalization for each cable microcell integrator.

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.

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.

Abstract: A method and apparatus for providing wireless signal communications through multiple coverage areas that include narrow corridors along which much of the mobile traffic travels. The corridors are interconnected at junctions where vehicle traffic tends to slow down or stop. The invention in particular, involves a method whereby simulcast communication is used for signal communication among base station locations along the narrow corridors. In this simulcast mode, the system equipment uses the same radio frequency to provide wireless coverage in a sequence of related sites located along the corridor. Using simulcast channels, the need for handoff is reduced and or eliminated. At the junctions, the usual base transceiver station (BTS) arrangement may be provided whereby multiple radio channels are available and handoff processing occurs.

Abstract: A wireless telephony system is described wherein remotely distributed transceivers, each of which has only a single antenna for receiving signals from wireless telephones, and such remote transceivers are located close enough so adjacent transceivers receive signals from the same wireless telephones to provide reverse link antenna diversity to help prevent loss of signal from a wireless telephone.

The simplification is accomplished by reducing the number of frequency translation steps between elements of the centrally located equipment by using the same carrier frequency for signal handling within the elements of the centrally located equipment as is used to transmit telephony signals between elements.

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.
