现代化城市的快速发展导致城市的移动通信的无线传播环境复杂,尤其是很多高层建筑内各种材料对电磁波的穿透损耗较大,单一室外站点覆盖不能满足室内移动通信的需求,因此又产生了作为延伸覆盖的室内分布系统,本文在分析GSM及室分原理基础上,对现网部分区域的室内覆盖的测试分析,说明其室内覆盖中分布天线位置设计选择的重要性。GSM网络是目前提供移动通信服务的主要网络,在高楼林立的大、中城市GSM网络主要由解决室外覆盖的室外宏站和补充室外覆盖不足、解决深度覆盖的室内分布系统组成,GSM网络发展到今天容量受限,可通过合理
The rapid development of modern cities has led to the complicated environment of mobile communication in cities. In particular, the penetration loss of electromagnetic waves by various materials in high-rise buildings is large. The coverage of a single outdoor site can not meet the demand of indoor mobile communications. Therefore, As an extended coverage indoor distribution system, based on the analysis of GSM and room division principle, this paper analyzes and analyzes the indoor coverage in some areas of the existing network, and illustrates the importance of the design choice of distributed antenna location in the indoor coverage. The GSM network is currently the main network providing mobile communication services. In the large and medium-sized high-rise GSM networks, the GSM network mainly consists of an outdoor macro station that solves the outdoor coverage and an indoor distribution system that complements the outdoor coverage and covers the depth coverage. The GSM network has evolved to Today’s capacity is limited and can be justified
