APPARATUS AND METHOD FOR DETERMINING THE LOCATION OF A MOBILE DEVICE USING MULTIPLE WIRELESS ACCESS POINTS Amethod and an apparatus are provided for determining the location of a mobile device using multiple wireless access points, each wireless access point comprising multiple antennas. Theapparatus and method areparticularly suited to location of a mobile device in an indoor environment, such as a building. The method includes receiving a communication signal from the mobile device at each of multiple antennas of said multiple wireless access points; for each wireless access point, determining angle-of-arrival information of the received communication signal at the wireless access point, based on a difference in phase of the received signal between different antennas; collecting, from each of the multiple wireless access points, the determined angle-of-arrival information for the received communication signal from the mobile device; and estimating the location of the mobile device from the collected angle-of- arrival information. |
