Abstract
Wireless radio transmission at Medium Frequency (MF) is feasible for both personnel and vehicular communications in underground mines. MF radio does not suffer from the severe corner losses and leaky feeder installation requirements of Ultra High Frequency (UHF) radio. Propagation data obtained in both coal and metal/nonmetal mines has encouraged several organizations to develop portable and base station equipment.
