Design of UHF RFID reader based on software radio

As nowadays the operating frequencies of RFID system are diverse,system standards are too many and have great difference,which is not suitable for variety of tags to be used simultaneously,a method to design a RFID reader based on software radio and LabVIEW is proposed.By loading different software codes,the simulation reader is able to operate the RFID tags in accordance with different standards and different frequency bands,including reading and writing.Comparing the read re sult with that of the standard reader,the simulation reader realized the readout of the RFID tag information successfully,with which the cost of having to configure the different types of RFID readers to deal with variety of tags is reduced.
