Abstract: Due to the special condition and complexity of the areas such as underground temporary roadway and the coal face, traditional communication methods cannot meet the requirements. Based on IEEE 802.15.4 protocol, this paper proposed the design proposal for one type of portable ad hoc network voice communication system by taking advantages of ZigBee technology, including low power consumption, short time-delay, small volume, strong flexibility and so on. Besides, principle of operation for the proposed system was introduced and field experiments were conducted. The results showed that the designed system can meet the requirements for underground temporary roadway construction and emergency rescue.
