Research On Design And Construction Of TD-LTE Indoor Distribution System

With the progress of society and the popularity of mobile communication,the scale of mobile users is expanding rapidly.To develop in the mobile network signal,seamless coverage of the current urban outdoor has basically achieved the signal,but the signal coverage is still difficult to meet the needs of users of mobile communication is increasing,especially in the high speed download,in order to adapt to the traffic and data traffic,to provide more quality services and more good experience for users,operators to establish a market advantage,and create more economic benefits for the enterprise,to analyze and discuss the construction of indoor distribution system is the realization of mobile communication network is the inevitable choice of deep cover.This paper summarizes the general situation of wireless network development.The reinforced concrete structure is the main type of urban building,and the whole enclosed decoration form greatly weakens the radio signal,which leads to the difficulty of ensuring the quality of the call.In this context,this paper studies the TD-LTE indoor distribution system.First introduces the main technology used in the system,and then discusses the basic principles of system design and construction standards,from the source selection,way,link budget,antenna system design and construction of the construction project.The modification of TD-LTE system of Nanjing Center for the design of the test cases,in accordance with the free space loss and link budget are tested according to the test results of signal,the power range of the antenna port,and the layout of the antenna.After the completion of the project was put into operation,on-site network optimization test and network management statistics,the results show that the system can meet the coverage requirements,and can prevent leakage,the indicators improved significantly,the user satisfaction has improved significantly.This paper has some guiding significance for the design and construction of TD-LTE indoor distribution system.
