First of all

this paper introduces the two coverage problems of high-speed railway

and summarizes the four coverage mode of domestic existing high-speed railway mainstream. Especially

for proprietary high-speed railway network structure is briefly introduced in this paper. At the same time

the paper analysis the effective coverage level range value through the carrier-to-interference ratio

voice quality

based on a high-speed railway network GSM and TD-SCDMA mass data. Secondly

the high-speed railway network is divided into scenarios station spacing. Effective coverage level and the cost of three factors were comprehensive evaluation and put forward the corresponding site design suggestions. Finally

combined with the two cover difficulties of high-speed railway has carried on the forecast to the future high-speed railway cover pattern.
