First Claim
Patent Images
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.

Abstract
A probabilistic prediction is made of the location of a wireless-enabled mobile station in a wireless local area network. The prediction includes calculating a vector representing movement of the mobile station through a space in which two or more access points of the network are located, and determining a region surrounding the vector in which the mobile station has at least a given probability to be located within a certain period of time.

8. A method for probabilistic prediction of a location of a mobile station in a wireless local area network, the method comprising:
-
calculating 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 as said mobile station moves from a stationary state, said region is a deformed circle that is deformed in a direction of motion of said mobile station, and wherein said mobile station comprises a wireless local area network controller that enables said mobile station to communicate over said wireless local area network. - View Dependent Claims (9, 10, 11, 12, 13)

14. A server comprising:
-
an antenna; a radio coupled to said antenna; a wireless local area network controller coupled to said radio through which said server is able to communicate over a wireless local area network with mobile stations; a processor coupled to said wireless local area network controller; and memory to store code which, when executed by said processor, collects data of when, where and at what received signal strength indication said mobile stations roam and dynamically calculates therefrom a coverage area of an access point in said wireless local area network. - View Dependent Claims (15, 16, 17, 18, 19, 20)
