Design of UHF RFID emulators with applications to RFID testing and data transport

The electronic design requirements and applications for a UHF RFID tag emulator are presented. As motivated by present-day industry needs, several implementations of UHF RFID tag emulators are discussed with particular focus given to the use of the emulators as a general-purpose testing tool for RFID system design and on-site measurements. Several noteworthy results of UHF system testing are mentioned. As a longer-term development, the emerging use of UHF RFID protocols for general-purpose wireless data communications is also discussed.
