| China is now in the period of high development of rail transit construction,as the China Tower Company was established,the construction mode of rail transit civilian communication system would change.Therefore,in this context,it is significant for us to research on civilian communication system construction for the rail transit.The network access demand of current and future development for three telecommunication operators is adequately considered in this thesis.Combining the real information from field investigation with various scientific methods such as interference analysis,capacity estimation,link budget and performance analysis,it adopts the civilian communication system construction scheme which is scientific,reasonable and feasible for the rail transit.The scheme can not only satisfy the civilian communication system construction demand on line 1 rail transit in Guiyang,but also it provides such kind of subsequent construction with a crucial guidance in other domestic cities.The main jobs and achievements in the thesis as follows:1.The major factors and difficulties considered in the civilian communication system construction for the rail transit are introduced.The demand on standard and quality considered in the civilian communication system construction for the rail transit is discussed.The latter part of evolution need for telecommunication operator system is discussed.2.The key points are analyzed on the civilian communication system construction for the rail transit.The crucial equipment selections are discussed in the civilian communication system construction for the rail transit.Both feasible and effective support schemes for civilian communication system are adopted.3.The achievement of this paper gives some guidance to the subsequent civilian communication system construction for the rail transit in other cities,however,this paper is lack of consideration in 5G network,hoping to be more comprehensive in further research. |
