针对井下有线通信系统铺设困难和无线通信系统易受井下空间约束、带宽衰减快、传输距离短的缺点，设计了一套基于有线xDSL和无线Wi-Ei协议的多媒体综合通信系统。经过验证，该系统传输速率高，通信距离长，适合井下多种数据实时融合通信的需要，是煤矿应急救援的综合通信中重要的信息平台之一。
針對井下有線通信繫統鋪設睏難和無線通信繫統易受井下空間約束、帶寬衰減快、傳輸距離短的缺點，設計瞭一套基于有線xDSL和無線Wi-Ei協議的多媒體綜閤通信繫統。經過驗證，該繫統傳輸速率高，通信距離長，適閤井下多種數據實時融閤通信的需要，是煤礦應急救援的綜閤通信中重要的信息平檯之一。

According to such shortcomings as difficulties of lying wire communication system underground and the un- derground space restriction, quick bandwidth attenuation and short transmission distance of the wireless communica- tions system, an integrated multimedia communication system was designed based on the cable, xDSL, and wire- less, Wi-Fi protocols. The verification shows that such a system is of high transmission rate and long communication distance, satisfying the need of various real-time data integrated communications underground and it becomes one of the important information platforms in the integrated communications for coalmine emergency rescue activities
