Planning Of Wireless Signal Coverage Along High Speed Rail For 2018-2020 Years In Huaian

In the past ten years,China's public transport has developed rapidly,and the main domestic transport lines have been basically covered by high-speed railway.High-speed rail is much faster than traditional land transportation.As an efficient and economical inter-city transportation mode,it is becoming the first choice for people to travel for medium and long distances.With the advent of the Internet plus era and the continuous development of intelligent terminals,there are more and more mobile office and network entertainment needs when users travel by high-speed rail.How to cover the high-speed rail mobile network and meet the users' wireless network needs,especially after the establishment of the tower company,how to meet the coverage needs of three domestic operators through one-time site planning,it is necessary to conduct preliminary analysis and research.In this thesis,the main technologies of LTE wireless network are described,and the planning and objectives of high-speed railway wireless network are studied.The coverage of new high-speed railway mobile communication network in Huai'an area is mainly planned.The main contents are as follows:(1)Starting from the basic principles of mobile communication network,the main characteristics of LTE technology,the theory of wireless transmission and the model of LTE wireless transmission are discussed,and the basic concepts and processes of wireless network planning are preliminarily studied.(2)Starting from the requirement of high-speed rail wireless private network coverage,the main problems affecting the signal coverage of high-speed rail mobile network,such as Doppler frequency shift and signal switching,are analyzed,and solutions at various levels,such as algorithm correction,equipment cascade response,antenna-feed pertinent layout,network formation response,are given.(3)Starting from the target of Huai'an high-speed railway wireless network coverage,combining with Huai'an political,economic and social development environment,Huai'an high-speed railway planning and construction status,Huai'an mobile communication network basic situation and other factors are analyzed,and the planning principles and construction strategies of high-speed railway special network are determined.(4)Combining with the three high-speed railway networks covered by the tower,the plan of high-speed railway macro base station,room division,matching and transmission is designed,and the corresponding investment plan is obtained.According to the construction plan of the planned output,some sites have been built and all sites are planned to be completed in 2019 and 2020.
