Abstract: The paper introduced a mine-used CDMA wireless communication system based on the Telecom Public Network. The system introduces the Telecom Public Network CDMA signals into coal mine underground and makes integration of the Telecom Public Network CDMA signals and underground CDMA signals, which can ensure covering wireless signals in mine area and meanwhile the mobile phone users can freely roam in whole country. The system can also expand functions of PTT talkback, data and video communication, remote monitoring and management of hidden danger with mobile phone on CDMA network platform.
