目前国内的室内分布系统存在四方面的不足,一是室内移动通信环境差;二是由于建筑物自身对无线电波的屏蔽和吸收,室内易出现信号盲区,覆盖面窄;三是闹市区容易出现无线信道拥塞现象,局部网络容量不够;四是高层室内由于存在无线频率干扰,服务信号质量差。LTE室内分布系统的建设,不断可以改善室内的通话质量,扩大网络容量,营造了高质量的室内移动通信环境,从整体上提高移动网络的服务水平。
At present, there are four problems in the indoor distribution system. One is the poor indoor mobile communication environment. The other is that the building itself is blind to radio waves and has a blind spot in the interior and a narrow coverage area. Thirdly, downtown is prone to wireless Channel congestion, local network capacity is not enough; Fourth, high-level indoor due to the presence of radio frequency interference, poor quality of service signals. The construction of LTE indoor distribution system can continuously improve indoor call quality, expand network capacity, create high-quality indoor mobile communication environment and improve the service level of mobile network as a whole.
