Abstract
Embodiments of methods for determining a location of a mobile device, a mobile device, and a location beacon system are described. In an embodiment, a method for determining a location of a mobile device involves receiving, at a dual-antenna receiver of the mobile device, a plurality of ultra wide band (UWB) signals from a group of unsynchronized beacons having a quadrilateral formation, at the mobile device, determining angle of arrival (AoA) information from the UWB signals, and at the mobile device, calculating the location of the mobile device based on the AoA information. Other embodiments are also described.

A method for determining a location of a mobile device, the method comprising:
- receiving, at a dual-antenna receiver of the mobile device, a plurality of ultra wide band (UWB) signals from a group of unsynchronized beacons having a quadrilateral formation;
- at the mobile device, determining angle of arrival (AoA) information from the UWB signals;
- and
- at the mobile device, calculating the location of the mobile device based on the AoA information.
A mobile device, the mobile device comprising:
- a dual-antenna ultra wide band (UWB) receiver configured to receive a plurality of UWB signals from a group of unsynchronized beacons having a quadrilateral formation;
- a processor operably connected to the dual-antenna UWB receiver, wherein the processor is configured to:
- determine angle of arrival (AoA) information from the UWB signals;
- and
- calculate a location of the mobile device based on the AoA information.
