20100109847 | Collision resolution protocol for mobile RFID tag identifiaction - The performance of a radio frequency identification (RFID) system is improved by a protocol that eliminates collisions between signals generated by a) RFID tags that the RFID reader has already identified as being in its interrogation zone and b) RFID tags that are newly arrived and thus that the reader has not yet identified. This is illustratively accomplished by the use of separate identification and access frames. It is during the identification frame that newly arrived tags become identified by the reader. Although there may be collisions during the identification frame, those collisions are only among newly arrived tags. The already-identified tags communicate with the reader during respective time slots of the access frame, so that they neither collide with each other nor with the newly arrived tags. | 05-06-2010 |
