ABSTRACT:
The present invention provides a system and method of use for recovering data from an area. The data are gathered with at least one sensor converting the data to a digital packet. The packet is processed as encoded data and the encoded data is stored as a data frame. A reader transmits a signal to a plurality of the sensors and replicates the signal. Each sensor produces a reflected signal in response to the transmit signal and assigns a modulation frequency to the reflected signal. The reader receives the reflected signal. The reader separates frequency components of the reflected signal into upper and lower sidebands and separates the sidebands into data channels. The reader outputs the encoded data by processing the data channels. The reader decodes the encoded data to retrieve the data packet and the environmental data.
