Electromagnetic field immunity measurement method for wireless communication system by opened parallel wired cell

We study radiated radio-frequency electromagnetic field immunity test system for wireless LAN system by using opened PW (parallel wired) cell in which metal cover is removed. Leakage electric field at distance of 160 cm from the opened PW cell decreases until 30 dB, and then does not affect to operation of the AP (access point) composed of the wireless LAN system that communicates EUT (equipment under test) installed in the PW cell. We can measure dependencies of impinging level of disturbance wave on a throughput of wireless LAN system. As a result, it is confirmed that the radiated electromagnetic field immunity test system for wireless communication system can be composed by using the opened PW cell without affecting from impinging disturbance wave.
