室内覆盖室外内引方案实施探讨

Discussion on the implementation of interior guidance scheme for indoor coverage of outdoor

移动通讯3G、4G网络频率高,穿透力差,地下停车场,地下商超越来越多,对室内覆盖的建设和优化越发显得重要。然而公司投资成本有限,降本增效是计划建设努力的方向。传统的室分以及新型的DOTA在这样空旷的场景下,馈线长,天线多,投资高,维护难。本文介绍了一种简单易行的室外RRU内引的建设方案,既能达到覆盖要求,也能达到降本增效的目的。

At present, the outdoor network coverage of the city has basically achieved seamless docking, call quality has also been greatly improved. However, the construction and optimization of indoor network coverage have large room for improvement. For relatively open indoor buildings, such as shopping malls and supermarkets, the traditional indoor distribution construction has problems such as high cost, great difficulty in coordination, and difficulty in later maintenance. In order to reduce the construction cost and implementation difficulty and combine the actual demand, the method of ＂outdoor interior guidance＂ is considered to solve the indoor network coverage and achieve good coverage effect. Compared with the traditional indoor distribution, the ＂outdoor interior introduction＂ scheme, under the premise of ensuring less investment, is easy to implement as a whole, fast to build, convenient to maintain in the later stage, and provides faster and more stable communication services to indoor users, which is better realized to reduce costs and increase efficiency. Although, there will still be some weak coverage areas and the signal isolation will occur, but they are within the acceptable range of users. Therefore, the application of this scheme in underground parking lots, open supermarkets and shopping mails is of great advantage.
