Abstract: Methods for synchronizing multiple transceivers to a single master clock are provided including broadcasting a message from a master device, the broadcasted message including a device identification number identifying the master device to at least one known device within range of the master device; receiving the message at the at least one other known device and recording a time of arrival (Tarrival-kd) at the at least one other known device; repeatedly broadcasting and receiving messages and recording associated times of arrival at the at least one other known device; and applying a fit curve to the recorded arrival times to estimate a time of an event. Related devices and systems are also provided.

Abstract: Methods and systems are described for determining the shortest RF path in a multi-path environment. In an aspect a signal is transmitted by a transmitter. Multiple copies of the signal are received by a multi-directional receiver based on antenna elements that have a unique antenna pattern for each copy of the signal and where the copies are phase correlated and time synchronized. The copies are deconstructed into components of the reflected and line-of-sight waves of the transmitted signal. The shortest path is selected from among the reflected and line-of-sight waves using the deconstruction of the copies.
