Interference Analysis of Microwave RFID and 802.11b WLAN
In recent years, the proliferation of IEEE 802.11b WLAN (Wi-Fi), which occupies the 2.4-2.4835GHz frequency bands, make the 2.4GHz ISM unlicensed band more crowded. At the same time, the RFID technology emerged and will be widely deployed. RFID use diverse frequency bands from Low Frequency (LF) to Microwave, including 2.4GHz ISM bands too. Hence, when 2.45GHz RFID systems collocate with 802.11b, the mutual interference is inevitable and their performances will significantly degrade. The main goal of this paper is to evaluate the impact of mutual interferences on the performance of 2.45GHz RFID and 802.11b systems. A mathematical model is proposed to analyze the mutual interference, and Packet Error Rate (PER) is used as the performance metric. The simulation results of 802.11bs PER are illustrated, which compared with the theoretical results, to evaluate the performance degradation of the interference.
