Abstract :
The 802.11b physical protocols applied in Communication Based Train Control (CBTC) train-ground communication system are simulated in this paper, and the simulation result is used to determine the AP distance. The train speed impact on physical FER is also studied by the simulation result. As a protocol used in a fully mobile outdoor environment, the packet delay and packets loss rate performance of 802.11 DCF is analyzed at last.
