Abstract: Embodiments relate to a deployment of a master radio in conjunction with one or more slave radios. The master radio coordinates with a UE, or transmitter, to transmit a particular known set of wireless signals in a defined time window over a dedicated wireless connection between the UE and the master radio. The master radio separately coordinates with the one or more slave radios to monitor for and measure the dedicated wireless connection during the defined time window (e.g., to obtain AoA measurements, signal strength measurements, etc.). The measurements can be reported to the master radio or a separate measurement processing unit to facilitate a location determination of the UE.

Abstract: A location device (e.g., realized at one or more of a mobile device and/or a location server) includes a wireless transceiver, one or more location sensors and a floor-plan of a venue. The location device determines a plurality of hypothetical locations of a mobile device in the venue in response to data sets provided by the one or more location sensors. The data sets are associated with obstacle indication values calculated for the venue or for regions of the venue including locations corresponding to the data sets. The obstacle indication values indicate the proximity or orientation of the obstacle edges in the region or in the venue. The location device refines the one or more hypothetical locations based on the obstacle indication values to provide an estimate of the current location of the mobile device.
