【摘要】：近年來，隨著移動通信的飛速發(fā)展，手機已經逐漸成為一種現(xiàn)代通訊工具廣泛應用于人民群眾的日常生活，大多數(shù)的手機用戶不是僅僅滿足于良好的戶外移動通信服務�，F(xiàn)在多數(shù)建筑為采用高密材料且面積在數(shù)萬平米以上的封閉式建筑，由于室內布局的復雜性，不利于傳統(tǒng)宏站的深度覆蓋，致使室內覆蓋度不足，影響用戶的業(yè)務感知。隨著用戶對網絡質量關注度的不斷提高，解決室內覆蓋的問題已經箭在弦上。 針對室內覆蓋的難題，發(fā)展建設室內分布是解決該問題的重要途徑。與傳統(tǒng)宏站結構相比，室內覆蓋由信號源和室內分布系統(tǒng)兩大部分組成。室內分布系統(tǒng)可以直接有效的作用于建筑物內部，，減少墻體的穿透損耗，能夠更為全面的改善室內信號覆蓋強度，提升室內通話質量，并通過話務下次擴大網絡容量，緩解宏站的網絡負荷。 作者主要從室內覆蓋系統(tǒng)設計預評估、現(xiàn)網室分系統(tǒng)的優(yōu)化等方面入手，介紹了室分系統(tǒng)的網絡架構、發(fā)展趨勢，并通過結合工作案例，從系統(tǒng)性能、覆蓋能力、優(yōu)化標準對各方面進行了系統(tǒng)的研究和分析，總結了室內覆蓋系統(tǒng)的優(yōu)化原則和室內覆蓋系統(tǒng)的設計方案，研究了基于RRU新技術應用的室內覆蓋系統(tǒng)與傳統(tǒng)室內覆蓋系統(tǒng)方案的優(yōu)缺點，并通過在吉大一院的實際應用對比，驗證了RRU技術方案的可行性及各種優(yōu)點，論文最后根據理論分析，提出了分場景的RRU室內覆蓋系統(tǒng)的方案建議。
[Abstract]:In recent years, with the rapid development of mobile communication, mobile phone has gradually become a modern communication tool widely used in the daily life of the people. Most mobile phone users are not only satisfied with good outdoor mobile communication service. At present, most buildings are closed buildings with high density materials and area of tens of thousands square meters. Because of the complexity of indoor layout, it is not conducive to the depth coverage of traditional macro stations, resulting in insufficient indoor coverage and affecting users' perception of business. With the increasing attention of users to network quality, the problem of indoor coverage has been solved. In view of the difficult problem of indoor coverage, the development and construction of indoor distribution is an important way to solve this problem. Compared with the traditional macro station structure, indoor coverage consists of two parts: signal source and indoor distribution system. The indoor distribution system can directly and effectively act on the interior of the building, reduce the penetration loss of the wall, improve the indoor signal coverage intensity, improve the quality of indoor communication, and expand the network capacity next time through telephone traffic. Relieves the network load of macro station. From the aspects of pre-evaluation of indoor coverage system design and optimization of current network room subsystem, the author introduces the network structure and development trend of room sub-system, and through the combination of work cases, from the system performance, coverage capacity, and so on, the author introduces the network structure and development trend of room sub-system. The optimization standard has carried on the systematic research and the analysis to each aspect, has summarized the indoor cover system optimization principle and the indoor cover system design plan, has carried on the systematic research and the analysis to the indoor coverage system. This paper studies the advantages and disadvantages of the indoor coverage system based on the new RRU technology and the traditional indoor coverage system, and verifies the feasibility and various advantages of the RRU technical scheme through the comparison of its practical application in the first Hospital of Jilin University. Finally, according to the theoretical analysis, the proposal of scenario-based RRU indoor coverage system is proposed.
