The Research Of GSM-R Technology And The Design Of CIR

GSM-R is the private mobile communication system for railway, which is based on the ETSI GSM, the second generation of mobile communication system, It has already come into use in Europe. Wireless interface of GSM-R system is designed for high-speed railway with the velocity 500km/h, and suitable for the development and requirement of high-speed railway which also meets the demands of new-generation synthetical digital mobile communication network .Because GSM air interface accords with GSM standard, it is the only communication system at present which can supply special-purpose dispatcher's service in the smooth transaction toward the third-generation mobile communication system. Developing GSM-R technique adapts to the demand of Chinese transportation modernization .The paper is about a development item of Cab Integrated Railway which is brought forward by Ministry of Railway. Firstly, every aspect of GSM-R System is described and introduced detailedly. These aspects are as follows. GSM-R system frequency choice, the specific features of GSM-R, the implementation situation GSM-R system, as well as it's further development .by comparation of TETRA system and GSM-R system, it is concluded that GSM-R system is the best orientation suitable for applicant and development at the moment.I designed a terminal which is applied to GSM-R system, i.e. Cab...
