Abstract :
In this paper, the influence of the electromagnetic environment on RFID (radio frequency identification) systems is studied. By electromagnetic environment, we consider the electromagnetic waves interference on a RFID system performance produced by applications located nearby. In particular, we analyze the effects of using a GSM mobile phone near an UHF-868 MHz RFID system. For the tested configurations, the results show that the read range (the maximum distance of labels detection) of the RFID is considerably reduced. Also, the GSM mobile communication can be affected by the waves radiated by the RFID system.
