  • Methods and Apparatus for Driving Radio Frequency Transmitter Placement Via an Enhanced Coverage Metric
    Publication number: 20080182528
    Abstract: Systems and methods are provided for improving the placement of RF devices each having a position and a coverage area within an environment. The system operates by identifying a gap in the environment that is outside the coverage areas of the RF. A size of the gap and a relative direction of the gap from the position of one of the RF devices are determined. The position of the RF device is then moved in a direction corresponding to the relative direction to thereby reduce the size of the gap. The process can be repeated any number of times until a suitable placement scheme is achieved.

  • Method to sustain TCP connection
    Patent number: 7406061
    Abstract: The present invention relates to network communication systems for managing client/server connections in a wireless environment. In accordance with the invention, a mobile communication unit (i.e., client), deploys keepalive packets at selected times in order to reset a keepidle timer of a server (e.g., host computer). By periodically resetting the keepidle timer a current connection between the mobile communication unit and server can be maintained as long as desired even when the mobile communication unit is in a power suspend mode. When in a power suspend mode, the mobile communication unit can briefly awake long enough to activate its transmitter and send a keepalive packet to the server to maintain the current connection. In this manner, the mobile communication unit can obtain the power savings of being in primarily a power suspend mode, but still prevent the current connection from timing out.

  • Reverse infrastructure location system and method
    Patent number: 7403120
    Abstract: Methods and apparatus are provided to locate a terminal within a workspace. Radio frequency identification (RFID) tags are provided in known locations, preferably in, on or adjacent the light fixtures or other workspace infrastructure. The terminal comprises an RFID tag interrogation transceiver, processor and memory. The transceiver interrogates the tags which respond with information correlatable with their unique locations. The terminal determines its locations relative to the known locations of responding tags by, for example, varying its transmit power and/or receiver sensitivity and/or by trilateration using, for example, phase or time difference of arrival measurements on the tag response signals. Once it has determined its own location it may transmit or otherwise announce its location as desired by the user.
