Performance of IEEE 802.11b in mobile railroad environments

In this paper, as a part of our collaborations with the Federal Railroad Administration (FRA), we present our study of 802.11b performance characteristics for mobile railroad environments. Our investigation includes detailed modeling and analysis of 802.11b with Doppler shift impacts and other elements of MAC and physical layers. We also discuss our approaches to verifying our findings in a railroad environment through partnerships with Union Pacific and BNSF Railway. Keywords--IEEE 802.11b performance, wireless, mobility, wireless in railroads.
