Design Of Coverage Scheme For Metro Public Wireless Communication Network

Subway has become one of the important standards to measure urban construction,and the quality of subway construction directly determines the development level of the whole city.Subway is an important part of urban construction in our country.Usually,in subway construction,each wireless public network is designed independently of each other,and the network coverage is realized by single network coverage.However,due to the influence of special environment,there will be signal blind areas.In this paper,the subway tunnel coverage network technology will be studied,the effective application of this technology will be determined,and the role of the technology will be brought into full play.This way can improve the construction quality of subway tunnel and provide people with the same good living environment.To promote the good development of urban construction in China.Because of its fast,efficient,convenient and low energy consumption,the subway has become an essential way of transportation in the development of urban traffic.It is especially important to design the system to meet the actual needs and to meet the requirements of signal coverage.On the one hand,the service quality of the communication network can be enhanced;on the other hand,the service can be provided with the help for improving the traffic and operating profit,and the communication network has good social and economic benefits.In order to solve the network coverage requirement of public wireless communication in the subway,this study demonstrates the feasibility of the design based on the practical engineering case.The main contents include:(1)The signal coverage mode of subway wireless communication and the evaluation of coverage effect are analyzed,and the related design principles of tunnel interval range,such as public network coverage technology and tunnel sharing technology,are expounded in this paper.(2)Combined with the case,this paper expounds the concrete scheme of the subway public network wireless communication system.By connecting the wireless introduction and coverage system to the ground public communication wireless signal into the underground space,it has reached the underground station and the wireless signal in the underground range has been fully covered,so as to reduce or even eliminate the blind area of the signal.In order to meet the needs of good extension and coverage of operators’ public wireless signals,users can obtain higher quality mobile communication related services.(3)Through the feasibility analysis,the wireless coverage scheme of the public network wireless communication system based on the case is formed,and the related renovation work on the system aspect is introduced in detail.This paper focuses on the wireless coverage of subway tunnel section and station floor.Especially in the public wireless coverage system and related technology research has progressive significance.In addition,nowadays,the urban population density is high,the traffic travel pressure is great,the subway,as an important passenger flow hub,has an important function to the urban traffic travel.Due to the different level of economic development in different regions,there are also differences in the level of subway construction.With the increase of the number of mobile users,the demand for mobile communication is increasing significantly.It is urgent to improve the quality of mobile communication network in subway space.Subway comprehensive coverage of communication signals has become an important part of the construction of subway projects.Therefore,it is important to strengthen the design and research of public wireless overcoverage system.It should be of practical significance.
