Abstract: A method of determining locations of radio beacons includes: self-locating and automatically orienting electronic device hubs, determining angles of arrival of radio beacon signals at the electronic device hubs using received signal strength of radio beacons, refining received signal strength based on angle of arrival of the radio beacon signals, determining range using the refined received signal strength and antenna orientation based propagation loss models that compensate for obstacles in a deployment environment and, combining angles of arrival and ranges determined at the electronic device hubs at one of the electronic device hubs and determining locations of radio beacons within a predetermined acceptable accuracy, wherein the electronic hub devices function as receiving devices and radio beacons and radio beacon signals from a subset of the radio beacons are received at more than one electronic hub device.
