Abstract
Systems and methods for detecting the presence of a body in a network without fiducial elements, using signal absorption, and signal forward and reflected backscatter of radio frequency (RF) waves caused by the presence of a biological mass in a communications network.
Claims10
A method for estimating the number of humans in a space comprising:
- providing a plurality of transceivers in wireless communication with each other and disposed in a detection area;
- providing a computer server in communication with each transceiver in said plurality of transceivers;
- determining, at said computer server, a first signal profile for characteristics of wireless communications among said plurality of transceivers when no humans are present in said detection area;
- determining, at said computer server, a second signal profile for characteristics of wireless communications among said plurality of transceivers when a first plurality of humans is present in said detection area, the number of humans in said first plurality being known;
- determining, at said computer server, a third signal profile for characteristics of wireless communications among said plurality of transceivers when a second plurality of humans is present in said detection area, the number of humans in said second plurality being unknown;
- and
- using said first signal profile, said second signal profile, and said known number of humans in said first plurality of humans, estimating said unknown number of humans in said second plurality of humans.
