Devices, methods, systems, and computer-readable media for calculating a distance and direction from a location tracker to a location of a node are described herein. One or more embodiments include a transmit element to transmit a search command for a first node to one or more nodes, a receive element to receive wireless transmissions from the one or more nodes including range data between the location tracker and each of the one or more nodes, and a time of flight (ToF) ranging calculator to convert the range data to a distance measurement from the location tracker to the first node.
