SERVER FOR UPDATING LOCATION BEACON DATABASE
First Claim
1. A system comprising:
- computer-implemented logic to derive position information for each of a plurality of Wi-Fi access points in a geographic area having a radius on the order of miles, wherein the position information is derived at least in part from sets of data collected during a comprehensive traversal of the geographic area, each set of data including signal data characterizing one or more observed characteristics of a signal received from the Wi-Fi access point, and location data characterizing a location at which the one or more characteristics of the signal received from the Wi-Fi access point was observed; and
computer-implemented logic to store the derived position information in a non-transitory computer-readable medium.

Abstract
A location beacon database and server, method of building location beacon database, and location based service using same. Wi-Fi access points are located in a target geographical area to build a reference database of locations of Wi-Fi access points. At least one vehicle is deployed including at least one scanning device having a GPS device and a Wi-Fi radio device and including a Wi-Fi antenna system. The target area is traversed in a programmatic route to reduce arterial bias. The programmatic route includes substantially all drivable streets in the target geographical area and solves an Eulerian cycle problem of a graph represented by said drivable streets. While traversing the target area, Wi-Fi identity information and GPS location information is detected. The location information is used to reverse triangulate the position of the detected Wi-Fi access point; and the position of the detected access point is recorded in a reference database.
