【摘要】：隨著移動通信的快速發(fā)展,網絡規(guī)模的不斷擴大,基站數量的不斷增加,第二代移動通信系統(tǒng)在城市的室外已基本做到了無縫覆蓋,話音質量也得到不斷地提高和完善,然而,社會公眾對于移動通信服務質量的要求也在逐步提升。在室外需求獲得良好滿足之際,客戶要求在室內,特別是大型商場、高級寫字樓、超市、地下停車場等,也能享受優(yōu)質的移動通信服務。室內信號的覆蓋關系到移動通信的服務質量,現今隨著經濟的發(fā)展和城市的建設,建筑面積的擴大和建筑材料的復雜性,使得室內通話質量嚴重下降。移動通信市場的激烈競爭要求電信運營商必須通過提供優(yōu)質的網絡服務,才能贏得更大的市場份額,從而在激烈的競爭中取得有利位置。室內信號的覆蓋是移動網絡覆蓋的重要組成部分,其重要性是不言而喻的。對運營商來說,建立一個成熟、優(yōu)質的室內信號分布系統(tǒng),就顯得更加尤為重要。本文基于中國電信建設運營的CDMA2000業(yè)務,首先介紹了室內分布系統(tǒng)建設的背景、現狀以及其對于CDMA業(yè)務發(fā)展的重要性,其次介紹了室內分布系統(tǒng)的基本理論,然后介紹了室內測試的相關知識,而后結合天津大悅城的基本情況,進行了數據分析、預測,最后介紹了大悅城項目室內分布系統(tǒng)的解決方案。本文以天津大悅城CDMA室內分布系統(tǒng)方案為例,通過理論研究和工程實踐,探討大中型建筑物的室內覆蓋建設的解決方案,本文對室內分布系統(tǒng)的規(guī)劃、建設具有指導意義。
[Abstract]:With the rapid development of mobile communication, the expansion of network scale and the increase of the number of base stations, the second generation mobile communication system has basically achieved seamless coverage outside the city, and the voice quality has been continuously improved and improved. The requirements of the public for the quality of mobile communication service are also gradually improving. At a time when outdoor demand is well met, customers require that they can also enjoy high quality mobile communication services indoors, especially in large shopping malls, high grade office buildings, supermarkets, underground parking lots, etc. The coverage of indoor signals is related to the quality of service of mobile communication. Nowadays, with the development of economy and the construction of cities, the expansion of building area and the complexity of building materials, the quality of indoor communication is seriously reduced. The fierce competition in the mobile communication market requires that the telecom operators must provide high-quality network services in order to win a greater market share and thus gain a favorable position in the fierce competition. Indoor signal coverage is an important part of mobile network coverage, and its importance is self-evident. For operators, the establishment of a mature, high-quality indoor signal distribution system, it is more important. Based on the CDMA2000 service of China Telecom, this paper firstly introduces the background of indoor distribution system construction, the present situation and its importance to the development of CDMA service, and then introduces the basic theory of indoor distribution system. Then the related knowledge of indoor testing is introduced, and then the data analysis and prediction are carried out in combination with the basic situation of Tianjin Dayuecheng. Finally, the solution of indoor distribution system of Dayuecheng project is introduced. This paper takes the CDMA indoor distribution system scheme of Tianjin Dayuecheng as an example, through theoretical research and engineering practice, discusses the solution of indoor coverage construction of large and medium-sized buildings. This paper is of guiding significance to the planning and construction of indoor distribution system.
