Software Defined Radio Based Implementation of RFID Tag in Next Generation Mobiles

Radio Frequency identification (RFID) technology has become important tool for items identification and tracking. In those purposes different types of RFID technologies could be used, depending on its application. Limitations of passive RFID technology, related to tags reading range and confidence in harsh environments, puts restrictions on implementation in the real life scenarios. To overcome the issue, but staying within the standards, we have considered development and implementation of active backscattering tag technology, which significantly improves tag reading range and confidence. Software Defined Radio (SDR) technology is promising technology for building mobiles of multiple radio standards in 4G networks. Regarding stated RFID technologies limitations and SDR technology, we present development and implementation of the Software Defined Radio (SDR) active backscattering tag compatible with the EPCglobal UHF Class 1 Generation 2 (Gen2) RFID standard. Such technology can be used for wide spectra of applications and services. The system is developed and tested on SDR platform. Validity and performances of developed Gen2 SDR tag are shown through actual presented results.
