RFID is a revolutionary step in wireless technology, which can be deployed for identification and tracking of objects. This technology is complex and expensive, but decrease in cost of VLSI components gives a pathway to this technology into developing countries. In RFID, the communication takes place between the tags to the reader and vice versa. In this paper, the authors simulated the tag to reader communication of an EPCglobal Gen-2 RFID system with the aid of GNU Radio, a free software development toolkit that provides the signal processing runtime and processing blocks to implement software radios using readily-available, low-cost external RF hardware.
