Abstract
The disclosure provides examples of systems and methods for determining locations of a number of radio frequency-enabled devices such as mobile devices and radio frequency-equipped beacons/luminaires within an indoor location. The radio frequency-enabled devices may be part of an indoor positioning system and/or content delivery system. The examples describe obtaining an angle of arrival (AoA) of the signals received by the respective radio frequency-enabled devices. The AOA data is used to identify the relative positions of the radio frequency-enabled devices as the mobile device moves about the indoor location. Upon comparing AOA measurements of the collected data related to a map of the location, the system may generate a data structure that may be presented graphically as a map of positions of the devices at the location. The described examples may enable a rapid commissioning process with respect to the radio frequency-enabled devices in a network.
