Noble Bandwidth Requirement Estimation method for Wireless Railway Communication System

초록

Sophisticated bandwidth requirement estimation method for wireless railway communications system is introduced in this paper. To derive optimized frequency requirement calculation method, ITU-R M.1390 and 1768 are analyzed and compared. After that, we define and segment the services required for the next generation railway communication system. A data on equipments that is installed on the actual fields are allocated to the parameters of the calculation process. Consequently expected frequency requirements of present, 5 years later, 10 years later will be presented.
