  • Publication number: 20010037395
    Abstract: An architecture for providing operations and maintenance functionality in an open access wireless signal distribution system. The open access system makes use of a common, shared, distributed radio frequency distribution network and associated network entities that enable a system operator to offer access to wireless infrastructure that maybe shared among multiple wireless service providers (WSPs). The WSPs, or tenants of the operators, may obtain access in a tenant lease-space model. The open access system provides the ability for multiple tenants in a given community to share wireless equipment such as remotely located antenna sites, regardless of their specific requirements for radio frequency (RF) air interface signal protocols and/or management messaging formats. The present invention is directed to an open access Network Management System (NMS) that provides multiple tenants with an appropriate level of access and control over the system elements that carry their signaling.

  • 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.

  • Patent number: 5973647
    Abstract: A leaky waveguide antenna array that receives and/or transmits electromagnetic signals includes a plurality of radiation waveguides disposed in parallel to each other on a surface plane to form the antenna array. A feed waveguide is located below the surface plane and provides an electromagnetic signal to the plurality of radiation waveguides and/or receives a plurality of electromagnetic signals from the plurality of radiation waveguides and provides a composite electromagnetic signal at an output of the feed waveguide. Each of the plurality of radiation waveguides has a waveguide axis and includes a plurality of apertures arranged in a direction of the waveguide axis. The feed waveguide includes a first section of waveguide having a first end connected to an input/output port. The first section of waveguide has a height substantially the same as the height of each of the plurality of radiation waveguides and the first section of waveguide has a second end coupled to a first junction point.
