Abstract
A communication system that communicates for locating one or more tags in a time and energy efficient manner. The tags are positioned in a communication region and are located by a locator. The tags are located through organized transmission and reception of signals between the tags and the locator. The locator locates and gives directions to tags from the locator using a radio link and a multi-channel ultrasonic acoustic link. The combination of linkages provides the means to determine the unobstructed bearing and distance between the locator and the tag and resolves multipath reflections.
