DEFINING A RADIO FREQUENCY IDENTIFICATION READ AREA |
摘要 |
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. |

1. A system for defining a radio frequency identification read area, the system comprising:
at least one radio frequency identification (RFID) reader operable to read RFID tags within a specified read area; at least one RFID transmitter coupled with the at least one RFID reader, the at least one RFID transmitter operable to radiating a modulated carrier in an area adjacent to the specified read area; wherein the at least one RFID reader is operable to control the at least one 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 at least one RFID reader. |
