Real-Time Propagation Measurement System and Scattering Object Identification by 3D Visualization by Using VRML for ETC System

<p/> <p>In the early deployment of electric toll collecting (ETC) system, multipath interference has caused the malfunction of the system. Therefore, radio absorbers are installed in the toll gate to suppress the scattering effects. This paper presents a novel radio propagation measureme...
