Abstract
A device may request location information for a location reference device (LRD); receive, based on the request, the location information for the LRD via a cellular network connection; transmit, via the cellular network, an instruction to direct the LRD to activate a non-cellular radio on the LRD; receive wireless signals outputted via the non-cellular radio; determine a distance between the user device and the LRD based on a strength of the wireless signals received by the user device; and audibly or visually indicate, by the user device, the determined distance between the user device and the LRD.
