Reseach of Wireless Transmission Characteristics of ZigBee in Mine Tunnel

Wireless transmission characteristics of ZigBee were tested and researched in simulated mine environment by use of underground straight tunnel. Firstly, path loss coefficient model was taken as wireless transmission model of mine tunnel, then some communication indexes were tested by use of two GAIN...
