A New Method of Underground Radio Noise Distribution Measure

The performance of the wireless communication system depends on the designer’s understanding to the regular pattern of environment electrical noise distribution in which the communication system is located. The lack of the knowledge of the underground coal mine’s electrical noise distribution usually led to the current common practice as directly adoption the terrestrial wireless communication systems property index when design the underground coal mine’s wireless communication system. The huge difference does exist between the underground coal mine’s electrical noise distribution and the terrestrial counterpart, which usually causes the underground wireless communication system’s decline in the communication quality, or not functioning properly. As the special circumstances of underground coal mine makes it difficult to apply the terrestrial electrical noise measurement method in the underground, this article presents a new method for measuring the electrical noise in underground coal mine, which has been successfully applied in measuring the typical underground coal mine’s electrical noise distribution.
