Performance Evaluation of Millimeter-Wave-Based Communication System in Tunnels

This report presents performance evaluation of a prototype of a millimeter-wave-based communication system in tunnel environments. The prototype could give 500 Mbps of data rate throughout 1.1 km on a straight route. The data rate dropped from 500 Mbps to 100 Mbps while a receiver of the prototype passed by 530-m point on a curved route. The results can be used to determine appropriate locations of trackside radio components to achieve enough coverages in a system deployment for railway communication networks.
