The Realization Of High Speed Railway Wireless Communication And Network Optimization

As China entered the high speed railway (HSR) age, the travelers are deeplyattracted by it for its fast, low-cost and convenient service. Increasing number ofpeople choose HSR to replace other modes of transportation. According to thehigh-speed environment of the radio waves propagation, the supporting wirelessnetwork must be improved. This paper studies from the wireless radio wavespropagation characteristics under the environment of high speed, analysisies andverifies the physical phenomenons such as fast fading, Doppler effect, penetrationloss that hinder the wireless communication, and expounds the demanded points ofthe the technical indexes. Then this paper discusses now commonly used in networkscheme and network optimal policy, and will they do the contrast between,demonstrates the different environment needs the different network scheme.This paper not only has a detailed theory system and application solutions, butalso combined with the engineering examples to discuss and verify the HSR wirelessnetwork coverage scheme and network optimization. From the road test data analysisto draw relevant conclusion, this paper more comprehensively discusses how to set upthe high quality wireless network and maximizing to optimize the networkoptimization in the practical project.
