Owing to noise in industrial environment, wireless signal is seriously interfered in industrial environment, and wireless communication quality will be affected seriously. Requirements of industrial wireless network and the wireless network standards are analyzed in this paper. The wireless communication quality model of IEEE 802.15.4 and IEEE802.11b is deduced. The simulation system based on this wireless communication quality model is established by Matlab. The simulation presents and compares communication quality of IEEE 802.15.4 and IEEE802.11b at the industrial noise range (typically between 20dB and 80dB) and security level (IEC61508 defined standard-SIL1, SIL2 and SIL3).
