Application Of City Rail Transit Special Wireless Communication System Based On TETRA

Nowadays, TETRA is one of the most advanced digital wireless cluster communication system,which is more and more widely used in the special wireless communication system. This article isabout the research and supposal on Changzhou rail transit wireless communication system based onTETRA.First of all, this article explains what TETRA is, including its construction, technology,characteristics, band, networking mode and so on. And then, London metro, New York metro,Guangzhou metro and Nanjing metro are listed as examples to show how widely TETRA is used oncity rail transit at home and abroad. Its condition about widely used is also analyzed to show itsfeasibility on city rail transit. After that, according to the preliminary design of Changzhou railtransit wireless communication system, the condition of project is analyzed which is focused on itsfunction, plan, construction and technology index. Combine the analysis of its function and the fact,Dimetra IP digital cluster system is suggested to be applicated in network technology. Also thetechnical scheme is given with the overview about secondary development system and details ofsecondary development Application Program Interface. And finally comes the summarize andexpectation of the digital wireless cluster communication system.This article takes use of Changzhou rail transit wireless dispatching system as the background todiscuss the application of TETRA in city rail transit. Its deeply research not only has high value inuse but also can be referred to in the future project.
