1. A method for probabilistic prediction of a location of a mobile station in a wireless local area network, the method comprising:

  • calculating by said mobile station a vector representing movement of said mobile station through a space in which two or more access points of said wireless local area network are located; and

    determining a region surrounding said vector in which said mobile station has at least a given probability to be located within a certain period of time,wherein calculating said vector includes using signal strength information regarding signals received at said mobile station over said wireless local area network and using the locations of one or more access points generating said signals.
