Method, system and apparatus for locating a mobile communications device
First Claim
1. A method of locating a mobile communication device, comprising,receiving a data set comprising strengths of signals received at the mobile communication device from a plurality of wireless access points, said data set further comprising identifiers of wireless access points from which each said signal was received;
- determining a scaling factor, wherein said determining said scaling factor is based on an antenna strength of a survey device used to collect said record of signal strengths compared to an antenna strength of the mobile communications device;
receiving said scaling factor in conjunction with said data set;
determining scaled signal strengths from said strengths of signals by scaling said signal strengths by said scaling factor;
comparing said scaled signal strengths with a record of signal strengths of wireless access points at given locations; and
determining a location of the mobile communication device based on said comparing.

Abstract
A system, method and apparatus for locating a mobile communication device are provided. A data set is received, the data set comprising strengths of signals received at the mobile communication device from a plurality of wireless access points. The data set further comprises identifiers of wireless access points from which each signal was received. Scaled signal strengths are determined from the strengths of signals. The scaled signal strengths are compared with a record of signal strengths of wireless access points at given locations. Based on the comparing, a location of the mobile communication device is determined.
