1. A method for detecting human presence, the method comprising:
providing at least two transceivers exchanging data bi-directionally via wireless signals, said bi-directional exchange generating sets of wireless signals;
obtaining a first set of wireless signals from said sets of wireless signals, said first set of wireless signals having been generated when no human is present in an area where said wireless signals are being transmitted during said bi-directional exchange;
determining a first set of signal data, said first set of signal data comprising data about the properties of said first set of wireless signals, said property data being generated as part of said bi-directional exchange;
creating a baseline signal profile based at least in part on said first set of signal data, and representing characteristics of wireless transmissions between said at least two transceivers when no human is present in an area where said wireless signals are being transmitted;
determining a second set of signal data, said second set of signal data comprising data about the properties of a second set of wireless signals from said sets of wireless signals, said property data being generated as part of said bi-directional exchange;
determining whether a human is present within said area where said wireless signals are being transmitted, said determination based at least in part on a comparison of said wireless signal properties in said second set of wireless signal data to said baseline signal profile.
