The RFID Radio Channel Performance in the Vehicular Control

Executive Summary

Most terrestrial wireless communication systems operate in environments that present a multitude of RF propagation problems. The Radio Frequency Identification (RFID) System, a wireless communication system, applied to vehicular control, is a typical point to point communication system, which one, the radio link formed between the reader, working at the same time as base station and as an end user site, and the tag, the intermediate site, is exposed to electromagnetic disturbances, due reflections off objects in the environment. Meanwhile any misalignment between the antennas at the reader and the tag will result in a polarization mismatch, from which, added to the multipath propagation, the system will see a slight fall of some level of reduction efficiency.
