The Implementation And Analysis Of Mobile Communication Signal Coverage Project In Co-construction And Sharing Mode Based On MFDS Technology

At present,China Mobile,China Telecom,China Unicom and other China telecom operators in China,after years of construction,each operates many mobile communication networks;there are more than six kinds of wireless communication network,the wireless communication systems which work on communication frequency on different.With the establishment of China Radio and Television Mobile,the development of 5G technology and so on,the wireless network application environment will be more complex.From the user's point of view,an area must be covered with wireless signals of multiple operators in order to ensure the smooth flow of comAUnication.Therefore,it is necessary for a region to have AUlti system and AUlti band coverage with multiple carriers.China Tower Company was founded,for some mobile signal coverage in the scene,the use of the construction scheme of multi-service fiber distribution system technology,at the same time to achieve coverage of the three operators 2G,3G and 4G wireless signals.Unlike POI solution,there are many problems such as large input of carriers,large input,large system interference,and no monitoring.It is a feasible and cost-effective new solution to enhance the mobile broadband experience of users,it is very consistent with China Tower resource sharing mode of thinking.In this paper,the present situation and development of optical fiber distribution system are summarized firstly.The research background and related research situation and development trend of the technology are briefly introduced.Then the development history of mobile communication technology,network construction,major telecommunication operators in China,and the current development operations of indoor coverage of the main technology were introduced and compared,the paper gives the China Tower mode selection method.The paper makes a detailed discussion on the multi-service fiber distribution system technology,a detailed analysis based on the system development background,system structure,basic principle,performance evaluation system and scenario definitions and requirements.And then the pilot project of multi-service fiber distribution system is carried out.The design of the project and the testing and analysis of the service performance of the system are introduced in detail,compared with other methods,the advantages and disadvantages of the scheme are given.Finally,the paper summarizes the thesis and prospects the research on multi-service fiber distribution system,especially in the 5G era,the evolution of the technical scheme of the China Tower in indoor distribution system is considered.
