Modeling the RFID radio channel applied to vehicular identification as a waveguide environment

Radio Frequency Identification (RFID) Systems are a wireless communication. Recently they are being applied to vehicular identification in road and freeways. This motivates the analysis of the propagation environment for outdoor in such systems. The RFID Systems that are used for the vehicular identification consists of the reader, the tag and the radio channel which is made up on the ground (asphalt), the free space and surrounded by irregular walls (buses, vans, sport cars, etc., located at adjacent lanes). In this work, the radio channel considering a tunnel environment and modeling as a waveguide is analyzed, in order to obtain the electromagnetic performance of the radio channel. The results show that the proposed model is suitable.

Some considerations about RFID system performance applied to the vehicular identification

When the RFID Technology is applied to vehicular identification, the objective is to have all the motor vehicle information inside the memory tag, and actually, it is limited to owner name, license, fines, etc. So, the focus of this work is to present some results of the experimental tests and measurements taken in the field and in the electromagnetic compatibility laboratory, from that, hint some parameters that should be readjusted when the application considers not only text information.
