The device includes a wireless transceiver, at least one antenna, a processor, and memory storing instructions. The instructions cause the device to conduct a plurality of wireless communications with the remote node including transmitting and receiving multiple wireless communications. Communication variables are generated based on the wireless communications, including one or more of a time of transmission, a time of arrival, or a calculated transmission time. A distance between the device and the remote node and a direction of interest toward the remote node is determined based on characteristics of signals received through the antenna, including phase differences or angle-of-arrival measurements. Location-identification data including the distance and direction relative to the remote node is generated and may be provided to an application that presents directional information identifying the remote node relative to the device. ## Claims ### Claim 1 An agent supportable device configured to determine location-identification data relative to a remote node, comprising: a wireless transceiver;
