Along with the increase of demand of radio communications and with the rapid progress of communication systems, the radio frequency interference of neighbor nations is a matter of argue. This problem is a delicate matter which must be dealt diplomatically with by having a distinct technical back ground. After the radio interference has been experienced in the Korean TRS service on the south seashore due to the base stations including the Fukuoka station in Japan, the radio interference problem between neighbor nations has become the matter of conflict. For the purpose to solve this problem, we has measured the radio waves that come from Fukuoka in Japan mainly to Pusan in Korea and also collected data in real-time.
