1. A method for detecting the presence of an object that affects RF signals comprising:
- providing a first transceiver disposed at a first location within a detection area;
providing a second transceiver disposed at a second location within said detection area; and
a computer server communicably coupled to said first transceiver;
said first transceiver receiving a first set of wireless signals from said second transceiver when an object that affects RF signals is present within said detection area at a first position;
said computer server receiving a first set of signal data from said first transceiver, said first set of signal data comprising data about properties of said first set of wireless signals;
said computer server creating a baseline signal profile for wireless communications from said second transceiver to said first transceiver, said baseline signal profile being based at least in part on said properties of said first set of wireless signals in said first set of signal data when said object that affects RF signals is present in said detection area at said first position;
said object moving from said first position to a second position in said detection area;
said first transceiver receiving a second set of wireless signals from said second transceiver when said object that affects RF signals is present at said second position;
said computer server receiving a second set of signal data from said first transceiver, said second set of signal data comprising data about properties of said second set of wireless signals; and
,said computer server determining if the position of said object that affects RF signals in said detection area has changed, said determination based at least in part on a comparison of said properties of said second set of wireless signals in said second set of wireless signal data to said baseline signal profile.

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.
