The Analysis of the Communication Distance in Wireless Optical Communications for Trains
Wireless optical communications is considered as a good way to provide big bandwidth for wireless communications. Therefore, the ground-to-train wireless optical communication can supply fast wireless communication service for running trains. In this paper, we demonstrate a system model to analyze and evaluate the communication distance in wireless optical communications for trains. After that, the simulation performance fully prove that the divergence angle and weather condition are two key factors that influence the communication distance. Moreover, the proper distance between two consecutive ground transceivers and the reasonable divergence angle are also displayed which have a significant meaning for guiding the deployment of ground transceivers.
