  • Method and apparatus for detecting and locating intrusion in a wireless network
    Patent number: 7570213
    Abstract: Method and apparatus for locating an intruding radio frequency signal in a wireless network. Relative distance measurements are computed between pairs of receivers from a plurality of receivers to the source of the intruding signal based on received signal strength. Loci of possible locations are plotted, points of intersection are determined, and a clustering algorithm is applied, yielding the location of the source of the intruding signal. The invention is distinguished in that its operation does not require knowledge of either the transmitted power or antenna gain of the intruding signal source.
