Compatibility between RFID and STL
China has issued document to assign the frequency band 840~845 MHz and 920~925 MHz for RFID application on April 23, 2007. However, as the frequency 920~925MHz was originally used by stereo transmit link (STL) service, the power emitted by RFID system will probably cause interference to STL system. This paper presents the methods of conduct measurement and field test to exhibit in what condition a RFID system will not cause performance degradation on STL system.
