1. A radio frequency identification (RFID) system comprising:

  • a) an RFID reader for communicating with RFID components (where RFID component is a tag or a sensatag) and decoding information from said RFID components;

    b) at least one said RFID component for communicating with said RFID reader using means of passive backscatter modulation;

    c) at least one said sensatag for receiving a signal from said RFID component, demodulating said signal and extracting the information from said RFID component that includes bitstream and relevant parameters, and communicating said received information;

    d) a data processing element for processing said information obtained by said RFID reader and said information obtained through said sensatags,whereby said RFID system can be used for localization, proximity detection, improving read rates, reducing unwanted reads, and making inference from sensor data.
