Douglas R. George has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8704711
    Abstract: The present invention is directed to systems and methods for enhancing link integrity between two wireless cable devices through automatic link acquisition and tracking. Embodiments of the invention utilize inexpensive motors and control components to automatically enhancing signal strength between a first wireless cable device and a second wireless cable device. Either the first wireless cable device, the second wireless cable device, or both may include an omnidirectional wireless antenna. Alternatively, the first wireless cable device, the second wireless cable device, or both may include a directional antenna. In another embodiment, the first wireless cable device, the second wireless cable device, or both may include both an omnidirectional antenna and a directional antenna.

  • Patent number: 8280443
    Abstract: Disclosed are systems and methods which provide high bandwidth data communication with respect to a large coverage area using smart antenna and/or directional antenna (referred to herein as multi-beam antenna) technology. Circuitry may be provided at a WLAN AP to provide selection of particular antenna beams used in the downlink and/or uplink, control of multicast transmission, control of unicast transmission, and to provide antenna pattern shaping techniques. Embodiments implement multi-beam antenna technology with little or no hardware modifications to AP circuitry. Other embodiments implement multi-beam technology using radio front-end and/or radio hardware modifications to AP circuitry. Various diversity techniques may be implemented, such as selection diversity, maximum ratio combining, and equal gain combing. To provide desired antenna pattern shaping, phase offsets with respect to a signal as transmitted in each antenna beam may be employed.
