Measurements have permit to develop and accurate propagation model for radio planning of antenna solutions in subway tunnels. It has been shown the higher attenuation rates in curves and places where changes in cross section or slope cause the blockage of the line of sigh. Some exceptions to well-known phenomena have been found in complex environments, like passing from open to tunnel or tunnels cross.
