Abstract
A method includes obtaining instructions at a mobile device comprising directions from a current location of the mobile device to a target location in a facility over a path identified by two or more waypoint devices distributed in the facility, receiving signaling over at least one wireless network from a selected one of the waypoint devices in the path, utilizing a radio frequency signal strength of the received signaling to estimate proximity between the mobile device and the selected waypoint device, presenting an indication of proximity to the first waypoint device via the mobile device based at least in part on the estimated proximity, determining whether the estimated proximity between the mobile device and the selected waypoint device is below a proximity threshold, and selecting another one of the waypoint devices in the path responsive to determining that the estimated proximity is below the proximity threshold.
