Recently, the current technology, WLAN a data communication device receiving worldwide attention, is operated on a 2.4 GHz ISM band. But since the ISM band is an unlicensed band used in a variety of low-power devices, there is a concern about radio interference between systems using the ISM band. With regard to this, IEEE 802.15 TG2 is operated on the basis of frequency coordination considering the radio interference between WLAN and Bluetooth [http:www.ieee802.org/15/pub/TG2.html]. However, there is insufficient research on the radio interference between WLAN and other radio devices. Therefore, in this paper, we explain the results of experiments conducted on the radio interference between the WLAN and other radio devices operated on a 2.4 GHz ISM band. Radio interference experiments were performed on the microwave oven which is easy to come across in our everyday living; the plasma lighting system (PLS), which is installed in hotels and other common places; and the video transmission device used in the wireless remote control robot for detecting explosives, which is operated in the airport, a hot spot area of WLAN. The results of the experiments will be utilized as data for more effective operation of WLAN.
