US Patent 7844237 Radio frequency signal for determining location

Systems and methods of position sensing for a receiver, via employing an ability thereof to receive signals in a broader range than what such receiver is initially tuned for. A frequency skip component can skip channel frequencies such that the spectrum range is scanned without a typical requirement of tuning to all the channels during such scan. Accordingly, the subject innovation enables the entire spectrum of interest to be scanned at a substantially reduced amount of time. Location interpolation for the receiver and time stamping of received signals can be implemented as part of the position sensing.
