  • Patent number: 9001811
    Abstract: A communication system to feed remote antenna nodes with simulcast traffic and non-simulcast beacons is provided. The communication system includes a host radio frequency (RF) digitizer, a delay buffer, a summing circuit, and a framer/serializer. The host RF digitizer receives CDMA base station signals for simulcast CDMA-traffic-bearing channels and to output digital samples. The delay buffer is communicatively coupled to receive the samples output from a beacon pilot generator and to output digitally delayed CDMA-digital-beacon-pilot samples having different pseudo-noise offsets. The summing circuit adds the CDMA-digital-beacon-pilot samples having different pseudo-noise offsets to the digital samples received from the host RF digitizer to form composite simulcast-plus-uniquely-offset-beacon-pilot CDMA samples.

  • Patent number: 8958789
    Abstract: An optical medium, such as fiber, is tapped to provide an antenna port wherever radio service coverage is desired. Each antenna port is a bi-directional remote unit that receives a digital optical signal from a host unit and transforms the signal to a radio frequency signal for transmission by the remote unit. The remote unit receives radio frequency signals that are converted to digital signals and summed with signals from other remote units and converted to an optical signal for transmission to the host unit.

  • Patent number: RE45321
    Abstract: A method and apparatus for sectorizing coverage of a cellular communications area includes providing a remote unit having microcell antenna units. Each microcell antenna unit is configured to cover a particular sector. The remote unit is connected to a sectorized base station unit which is connected to a mobile telecommunications switching office. Separate digitized streams representative of telephone signals received from the mobile telecommunications switching office are generated corresponding to the microcell antenna units and the separate digitized streams are multiplexed and transmitted to the remote unit. The remote unit demultiplexes the multiplexed digitized streams into the separate digitized streams corresponding to the microcell antenna units and the separate digitized streams are converted to RF signals for coverage of a particular sector by the corresponding microcell antenna unit.
