Design Of Wireless Indoor Distribution System Based On Multi–Networks

With the increasingly fierce competition in the telecommunications business,the new mobile Internet high-speed business is characterized by users of these business environment are mainly in the closed indoor environment,according to the telecommunications enterprise sampling statistics,more than 80 percent of the current traffic In a closed indoor environment.So the focus of full-service telecom operators from the voice business to data services,that is,profit from the traffic to indoor traffic.Indoor good network data service awareness led operators to focus on the competition in the indoor environment of the network construction,maintenance and optimization.Outdoor wireless signal due to the new office buildings,supermarkets,restaurants,transportation stations and other urban buildings block,channel fading,interference and other factors lead to lower user experience.To solve the contradiction between user needs and indoor key business quality,rational planning and design of indoor distribution system and continue to optimize the maintenance,is the operator's current focus on the work.In particular,China's current network status is the smooth evolution of a variety of networks,the traditional 2G,3G network and emerging 4G,WLAN,5G and other networks coexist,resulting in indoor distribution system design and optimization work more complex.This paper follows the COC principle of network construction project,and considers the signal coverage,service capacity and engineering cost,and studies the design and optimization of mobile communication indoor distribution system under the premise of balancing these three factors.This paper starts from the research and analysis of the domestic and foreign research status of the mobile communication indoor distribution system.Then analyzes the engineering process steps of the mobile communication indoor distribution system,discusses the key problems and solutions of the design of the mobile communication indoor distribution system from the single mobile communication indoor distribution system.In the current indoor building,the mobile communication network is analyzed,and the design and construction scheme of the mobile communication indoor multi-system is analyzed.At the end,the mobile communication room is distributed in the mobile communication room Distributed system test program,introduced the common optimization of the case and the process,to achieve the purpose of enhancing user awareness.
