Abstract:
This disclosure provides systems and methods for determining a location of a mobile device within an indoor environment. An embodiment of the system can have one or more positioning nodes (PONs), each having one or more antennas. Each PON can be disposed at a location within indoor environment and configured to transmit signals via the one or more antennas. The signals transmitted from the antennas of the PONs can be synchronized in time and frequency. A server communicatively coupled to the PONs and storing aiding information, including location and signal information related to the PONs, can transmit the aiding information to a mobile device. The mobile device can receive the signals from use the PONs and use the aiding information to determine a three dimensional position within the indoor environment based on one-way time difference of arrival of the signals.

Claim (Index 18):
A method for operating a mobile device to determine the location of the mobile device within an indoor environment, the indoor environment having one or more positioning nodes (PONs), each PON having one or more antennas, the method comprising:\n determining, at a mobile device, a coarse location of the indoor environment; transmitting a request to a server including the coarse location, the server storing aiding information related to the one or more PONs; receiving, at the mobile device, the aiding information from the server based on the coarse location; receiving a first positioning signal from a first antenna of the one or more antennas; receiving a second positioning signal from a second antenna of the one or more antennas, the second positioning being out of phase with the first positioning signal; receiving a third positioning signal from a third antenna of the one or more antennas, the third positioning signal being out of phase with the first positioning signal and the second positioning signal; and determining a position mobile device based on a one-way time-difference of arrival (TDOA) between the first positioning signal, the second positioning signal, and the third positioning signal.
