Research of Short Distance Wireless Communication Technology in the Mine Underground

According to the present situation of the wireless communication technology in the mine underground, the article makes a compare and analysis of the present of widely use of IrDA, RFID, Bluetooth, UWB and ZigBee etc. Short distance wireless communication, and designs the mine underground personnel positioning system using RFID technology based on the research of transmission characteristics of radio in the mine underground. It provides a feasible scheme for wireless communication technology in the mine underground. The experiment results show that if RF rate is set at 250Kbps, when people move, the network connection to the underground modulation assistant personnel carry identification cards, and the uplink and downlink can be observed in the computer, it can operate normally required in the design environment.
