The reliability EMC design of WIA-PA wireless networks equipment

This paper to improve the security and reliability of the WIA-PA Wireless Networks Equipment, by analyzed the signal noise and surge in the environment of industrial and Outdoor. At last this paper propose one solution of the EMC protection circuit, and expounds the circuit principle of the WIA-PA Wireless Networks Equipment. The solution was tested by the IEC61000-4-5 level 3 and experimental verification, which can effectively improve the security and reliability of the equipment.
