Abstract
A method of using one or more radio-frequency signals includes: monitoring, with at least one radio-frequency (RF) receiver, one or more RF characteristics of one or more wireless RF signals from one or more RF devices in an environment; comparing the one or more RF characteristics to a reference RF profile for the environment; and initiating an action based on a difference between the one or more RF characteristics and the reference RF profile determined by the comparing.
