Wave propagation experiences the excess loss in curved tunnels, which is highly desired to involve in the network planning for train-to-x communications. Extensive propagation measurements are conducted in a curved subway tunnel. By subtracting the measured received power in the curved tunnel from the simulated reference power in the equivalent straight tunnel, the excess loss resulting from the tunnel curve is obtained. Finally, tables and figures are provided to quantitatively reveal how the radius of curvature and frequency influence the excess loss in subway tunnels.
