Abstract

See full text

This disclosure provides a method and system for extending the capability of a proximity detection system that is based on use of low frequency magnetic fields, to avoid conflicts in crowded work sites. The improvement is attained by combining the advantages of these low frequency magnetic fields with the advantages of much higher frequency, radiated (RF) signals that are controlled to be produced at the same time, concurrent with each other, in a coordinated and/or synchronous manner.
