基于八通道RRU和立体双天线低成本覆盖居民小区的研究

Research Onlow-cost Mobile Signal Coverage of Residential Community Based on Eight Channel RRU and Stereo Dual Antenna

随着5G网络的快速建设,大量TD-LTE D频8通道RRU主设备退网,以及城市高层居民小区的不断出现,解决高层居民小区深度覆盖将是提升用户感知的有效和必然途径。文章提出一种基于8TR RRU的八个通道及立体双天线的低成本覆盖方案对居民小区进行深度覆盖。该方案更容易控制信号外泄、有效且更低成本解决了非容量热点楼盘的高中低层深度覆盖问题,开通的小区各项性能指标正常,达到了预期覆盖目标。

With the rapid construction of 5G network,a large number of TD-LTE 8-channel RRU main devices have becn retired from the network,and the continuous emergence of high-rise residential areas in cities,solving the deep coverage of high-rise residential arcas will be an effective and inevitable way to improve uscr perception.This article proposes a low-cost cover-age scheme based on 8TR RRU with eight channels and stereo dual antennas for deep coverage of residential areas.This solution makes it casier to control signal leakage,effectively and at a lower cost solves the deep coverage problem of high,medium,and low floors in non capacity hot spot properties.The performance indicators of the opened communities are normal,and the expected coverage goals have been achieved.
