基于电信公网实现的煤矿CDMA无线通信系统

CDMA Wireless Communication System of Coal Mine Based on the Telecom Public Network

介绍了一种基于电信公网建成的矿用CDMA无线通信系统。该系统将电信CDMA公网信号引入井下,使井下CDMA系统和地面已有的电信CDMA公网形成一体,可确保矿区无线信号的覆盖,同时手机用户也可以在全国自由漫游使用;在CDMA网络平台上还能够扩展PTT对讲、数据与视频通信、手机远程监测安全隐患与管理等功能。

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.
