Abstract This paper proposes a new direction to implement an underground mine communication system. It presents actual underground communication systems and discusses their technological limits. A new system based on a wireless local area network (WLAN), together with its main systems characteristics, is then proposed. This paper also presents an experimental protocol for radio frequency propagation measurements. Finally, the paper describes the projected implementation of a WLAN in an experimental mine.
Keywords: Communications cellular, Radio propagation, Radio frequency, Wireless local area network, Institute of Electrical and Electronics Engineers.
