Abstract
A radio frequency (RF) addressable sensor network includes (a) one or more RF addressable sensors; (b) one or more wireless sensor readers coupled to a communications network; (c) one or more end user devices coupled to the communications network, wherein the one or more wireless sensor readers communicate with the one or more RF addressable sensors to obtain sensor data for transmission over the communications network, the communications including common designation network communications; (d) a sensor network processor coupled to the communications network. The sensor network processor includes a geolocation processor and a sensor data processor. At least one of the wireless sensor readers is capable of powering down to conserve energy and capable of powering up in response to an electronic signal and includes a first receiver, a first transmitter, and a second receiver.
