摘要

The digital trunking communication is a major kind of emergency communication. Its application mode gradually changes from traditional voice dispatch to the broadband services. The market demand of the broadband digital trunking commu-nication is pointed out in this paper. introduces The application status of the broadband digital trunking communication systems at home and abroad is introduced. The development tendency and research hotspots of the broadband digital trunking communica-tion system are described briefly.%数字集群通信系统是应急通信的一种主要形式，目前逐渐由传统以语音调度为主的使用方式向宽带化发展。首先指出了当前市场对数字集群通信宽带化的需求，然后介绍了宽带数字集群通信系统在国内外的应用现状，最后对宽带数字集群通信系统的发展趋势及研究热点做了简要阐述。
