Abstract
Defining a radio frequency identification read area includes a radio frequency identification (RFID) reader operable to read RFID tags within a specified read area. An RFID transmitter is coupled with the RFID reader and is operable to radiating a modulated carrier in an area adjacent to the specified read area. The RFID reader controls the RFID transmitter to transmit the modulated carrier during a preamble transmission of the RFID reader to prevent any RFID tags in the adjacent area from recognizing an interrogation signal from the RFID reader.
