摘要
首先,分析CDMA2000 Ev-Do/GoTa集群通信系统的原理、网络架构和技术特点,通过比较欧洲的TETRA、美国的iDENY以及中国的GoTa3种集群通信系统,指出GoTa具有前两者无法比拟的优势。然后,结合非洲某国安全网项目,详细讨论了CDMA2000 Ev-Do/GoTa安全网网络规划、系统设计以及视频监控、紧急联动等业务应用系统设计。
This paper first introduces CDMA2000 Ev-Do/GoTa trunking communication system, network architecture, teeh- nieal teatures, etc. A simple analysis of the characteristics of several main digital trunking system technology is introduced subsequently. Then eo,nbined wilh the Africa country safety network project, network planning, system design for the CD- MA2000 Ev-Do/GoTa safety is deployed in detail. In the end, the service applications and design for the video surveillance and coalition emergency response syslem are discussed.
