摘要
4G通信技术是是集3G与WLAN于一体并能够传输高质量视频图像以及图像传输质量与高清晰度电视不相上下的技术产品。LTE作为4G通信的标准技术,提供了极高的数据传输率,同时也极大地改进了核心网性能。同时,LTE小区具有极大的网络覆盖范围,网络结构简洁,并能与IP网很好地融合,具有广泛的应用前景。LTE对于未来高速铁路信息化建设极其重要。本文设计实现的无线网络测试系统将无线通信测量数据与地理信息数据相结合,为铁路无线通信网络的规划与部署提供参考。
4G wireless communication technology is a successor of the 3G standards. It provides mobile ultra-broadband access, promoting the development of high-definition mobile video/TV, video conferencing and other mobile applications. LTE is marked as a 4G wireless service standard, has an increased capacity and data transfer speed. Besides, LTE has simple and clean network architecture, and will be well integrated with IP networks. LTE has great significance to railway communication systems. This paper designs a wireless network testing system, which combines traditional testing methods and GIS technology to assist planning the railway wireless communication systems.
