Claim:
1. A system for identifying a location of a subject relative to a facility, the system comprising: a kinematic sensor configured to detect a change in at least one of position, velocity, and acceleration thereof; a communications unit including: a housing structured to facilitate coupling of the kinematic sensor with the subject; at least two facility transceiver units in corresponding fixed locations, said at least two facility transceiver units configured to extract the first RF signal, relative to RF signal patterns that are caused by reflection and scattering of said first RF signal off of objects in the facility and that reduce a signal-to-noise ratio of said first RF signal, to produce an output signal; and a processor in operable communication with the at least two transceiver units, the processor configured to receive the output signal and generate data representative of a location of the kinematic sensor relative to the corresponding fixed locations.
