Your foot covers may be the mobile base station: new China Mobile base station construction details-IT information
China Mobile launched the manhole base stations, many students expressed doubts: how to install? How RF optimization? Will be watered down? Covers how? How has that worked? Today, small will take you to the site to find out deep Grill Grill cover from the base station planning and construction to optimize the whole process to unlock people's suspicions. Yueyang moved here, here is the cover base station installation site and welcome to the angry Biological Aerated live black technology ...
First broadcast a group of newsletters:
With the surge in the flow of people, 4G construction to promote in depth, however, the dense urban site of scarce resources and addressing new station fill blind contradiction between heating, therefore, move hand in hand Ericsson aims covers base station in Yueyang, construction 4G expanded into the ground.
Now everyone awaited the manhole base station to be unveiled ...
Jing Gaijun, please let me introduce myself ...
? Covers dedicated antenna
? Special precision bearing anti-tank
The following specific elements:
Coordinates: the electric power Bureau of Yueyang city district. The district has 30 years of history, the building density, flow of business and the location excellent. However, as the owners strongly opposed the new outdoor base station and visible antenna, resulting in serious shortage of in-depth coverage.
Professional descriptions are as follows:
Poor coverage in residential areas, average RSRP -100.81dBm, average SINR 6.25dB average upload speed of 3.09Mbps, average download speed 13.46Mbps, in-depth coverage within the corridor poor basic RSRP is less than -105dBm, causing some consumer complaints on the Internet is slow.
Despite objections from people to build an outdoor base stations, but we must not reset the communication difficult this problem is at stake.
To this end, the Yueyang Center for mobile network optimization to the scene conducted a number of feasibility exploration
After much research, many discussions
Finally, decided to adopt the new manhole covers solving actual coverage requirements of the system.
Says do it, go directly to the construction site ...
The entire installation process good concealment, project implementation, there is no resistance.
In fact, admission to the opening of the construction site, then to complete the test, it only took one day.
After the construction of a wireless environment ...
What effect? The problem is everyone's concern.
This is outdoor DT test before and after comparison chart ...
From cover to speed improved significantly.
This is indoor CQT testing comparison chart ...
Good description covers base station can solve the problem of indoor coverage issues.
In addition, on the manhole cover on the base station downlink peak rate test found that its field testing download peak 110.5Mbps, upload peak is 10.3Mbps, in terms of the rate of performance comparable with macro.
Finally, we care most about, would be flooded?
As of the release date, and cover system is opened for 4 days, after rain and snow and low temperatures during the bad weather, the KPI indicators are normal, reflecting the stability of the system.
Report is completed, is a summary of the time now.
The Yueyang, Hunan mobile pilot new manhole covers system, successfully avoiding the station construction difficult problem to solve the long-standing problem of signal coverage, people very satisfied, customer return rate has improved significantly. To this end, sum up the 6 major features of the programme are as follows:
1) antenna compact, light weight, easy location.
2) easy, in this case construction finished in 8 hours.
3) base station hidden, not easy to cause nearby property owners attention, even in the full open during the construction work.
4) in-depth coverage and low coverage significantly improved;
5) effective coverage radius of 150M;
6) system is stable, specializing in the design of the tank that can withstand harsh natural environment tested.
你脚踩的井盖可能是移动基站：
中国移动新型基站建设详解 - IT资讯
中国移动推出了井盖基站，很多同学表示存在疑问：如何安装？怎么做RF优化？会被水淹吗？覆盖怎么样？效果如何？今天，小编将带大家去现场一探究竟，深度扒一扒井盖基站从规划、建设到优化全过程，解开大家的疑惑。这里是岳阳移动，这里是井盖基站安装现场，欢迎观看本期怒曝黑科技现场直播...
首先播报一组简讯：
随着人民群众的流量需求激增，4G建设向纵深推进，然而，密集城区站址资源稀缺和新站寻址补盲补热之间的矛盾日益突出，为此，岳阳移动携手爱立信试点新型井盖基站，把4G建设工作向地下扩展。
现在有请大家期待已久的井盖基站闪亮登场...
井盖君，请自我介绍一下...
▲井盖式专用天线
▲特制精密承重防水柜
下面来看具体内容：
坐标：岳阳市电业局小区。该小区已有三十年悠久历史，建筑密度大，人流量多，商业和地理位置极佳。然而，由于业主强烈反对新建室外基站和肉眼可见的室分外打天线，导致深度覆盖严重不足。
专业描述如下：
住宅区域覆盖信号较差，平均RSRP为-100.81dBm，平均SINR为6.25dB，平均上传速率3.09Mbps，平均下载速率13.46Mbps，楼道内深度覆盖较差，基本RSRP都小于-105dBm，引起部分用户投诉上网速度较慢。
尽管人民群众反对建室外基站，但我们决不能置通信难这个问题于不顾。
为此，岳阳移动公司网优中心对现场进行了多次可行性勘查
经过反复调研、多次讨论
最后，决定采用最新型的井盖覆盖系统解决现场实际覆盖需求。
说干就干，直接进入施工现场...
整个安装过程隐蔽性好，工程实施快，还没有阻工。
实际上，从入场建设到站点开通，再到完成测试，只花了一天。
施工后的无线环境情况...
效果到底怎么样？这是大家都关注的问题。
这是室外DT测试前后对比图...
从覆盖到速率，改善效果明显。
这是室内CQT前后测试对比图...
性能良好，说明井盖基站可解决室内深度覆盖不足问题。
另外，在对井盖基站上下行峰值速率测试时发现，其现场测试下载峰值为110.5Mbps，上传峰值为10.3Mbps，在速率性能方面与宏站相当。
最后，是大家最关心的问题，会不会被水淹？
截至发稿日期，井盖系统开通4天，期间历经雨雪以及低温等恶劣天气，各项KPI指标均正常，体现了该系统的稳定性。
报道完毕，现在是总结时间。
此次湖南岳阳移动试点新型井盖覆盖系统，成功规避了建站难问题，解决了长期存在的信号深度覆盖问题，群众表示很满意，客户回访纷纷表示速率得到明显提升。为此，总结该方案的6大特点如下：
1）天线体积小，重量轻，易选址。
2）施工便捷，本案例在8个小时内施工完成。
3）基站隐形，不易引起附近业主注意，甚至在施工过程中全程无阻工。
4）深度覆盖和弱覆盖问题明显改善；
5）有效覆盖半径150M；
6）系统运行稳定，基于专业设计的防水柜可经受恶劣自然环境考验。
