Radio frequency identification (RFID) technology continues to receive attention in transport and logistics systems. Most of the previous work has focused on tag and reader configurations in distribution centers and retail outlets. However, the tracking and logging of freight movement has great promise for improving the timing and accuracy of supply chains since approximately 65% of all freight tonnage in the United States is transported by trucks and tractor-trailers. In a basic RFID tag read operation, the reader initiates tag collection and sends RF energy and messages to all tags. If messaging conforms to a defined protocol, then all of the tags present in a reader's field will respond by transmitting their tag ID back to the reader. The reader forwards all collected tag IDs to a computer network through a middleware platform that filters and aggregates data.This paper reviews the basics of radio frequency identification technology and the existing uses in commercial vehicle systems. The specific engineering design challenges associated with the metallic environments encountered in commercial applications are discussed. An empirical design method using a variable dielectric thickness is given. Experimental results for the use of RFID in the metallic environment encountered in a commercial vehicle demonstrate the validity of the design method.
