An investigation of millimeter wave propagation mechanisms for mobile intervehicle communications and outdoor MBS

Future intelligent transportation systems (ITS) and mobile broadband systems (MBS) will deeply rely on millimeter waves for communication purposes. Therefore their properties have to be known. In this paper, the propagation mechanisms of reflection and diffraction at curved surfaces at millimeter wave frequencies are investigated. They are classified with respect to the requirements of mobile intervehicle communications. The consideration of realistic street geometries and parameters leads to novel insights, which were formerly neglected.
