Recently, research on train virtual coupling and direct communication between trains is being conducted to further improve track capacity based on autonomous train driving. In this paper, we consider the IEEE 802.11ad standard using millimeter-wave bands (60 GHz) as a direct communication between trains. By constructing a train driving environment test bed to which direct communication between trains based on IEEE 802.11ad is applied, the direct communication throughput, received signal strength index, packet loss rate, and latency are measured and the results are discussed. Based on the measured results, the applicability and limitations of the millimeter-wave band wireless communication technology to the railway environment are considered. |
