  • System and method for improved spectrum use
    Patent number: 7551923
    Abstract: A method for improving the use of a transmission spectrum in a multi-sector wireless communication system includes generating a first signal, processing a first signal with a first Auto Tune Combiner, transmitting the first signal on an antenna associated with a first sector, sampling the first signal with a radio frequency test device, generating a second signal, processing the second signal with a second Auto Tune Combiner, transmitting the second signal on an antenna associated with a second sector, and sampling the second signal with the radio frequency test device.
    Type: Grant
    Filed: April 11, 2006
    Date of Patent: June 23, 2009
    Assignee: AT&T Mobility II LLC
    Inventors: Kraig Keys, Christopher Scott Erwin, Richard Bruno, David Bogart, Martin Chang
  • System for split transmission for enhanced spectrum utilization
    Patent number: 7200393
    Abstract: An apparatus for improving the use of a transmission spectrum in a wireless communications system. The apparatus includes a first radio source for generating a first signal, a first Auto Tune Combiner for processing the first signal, a first antenna associated with a sector for transmitting the first signal, a first radio frequency test device for sampling the processed first signal and producing a first feedback signal, a second radio source for generating a second signal, a second Auto Tune Combiner for processing the second signal, a second antenna associated with the sector for transmitting the second signal, a second radio frequency test device for sampling the processed second signal and producing a second feedback signal, and a multicoupler for directing the first and second feedback signals to the first and second radio sources.
