The forthcoming fifth generation (5G) cellular network will boost the Internet of Things (IoT) by enabling robust and ultra-fast worldwide connectivity among plenty of heterogeneous smart objects and wireless technologies. The need to identify and sense objects through ultra-low-power or zero-power communication mechanisms will be more crucial than now. In this framework, backscattering-based radiofrequency identification (RFID) technology could still play a major role through the possibility of implementing low-power identification and communication directly over other technologies belonging to the 5G ecosystem. Such aspect is investigated in this work where, without loss of generality, RFID capabilities are introduced over the X-band Doppler Radar Technology (DRT), typically used in IoT to detect and locate objects. Specifically, a first 10.525 GHz RFID microwave transponder fully compatible with traditional and inexpensive DRT-based motion detectors is designed, realized and tested. It is capable of backscattering an artificially generated Doppler wave modulating ID code and sensor data. The appropriateness of the proposed approach has been verified in a telemedicine test case.

Abstract
The forthcoming fifth generation (5G) cellular network will boost the Internet of Things (IoT) by enabling robust and ultra-fast worldwide connectivity among plenty of heterogeneous smart objects and wireless technologies. The need to identify and sense objects through ultra-low-power or zero-power communication mechanisms will be more crucial than now. In this framework, backscattering-based radiofrequency identification (RFID) technology could still play a major role through the possibility of implementing low-power identification and communication directly over other technologies belonging to the 5G ecosystem. Such aspect is investigated in this work where, without loss of generality, RFID capabilities are introduced over the X-band Doppler Radar Technology (DRT), typically used in IoT to detect and locate objects. Specifically, a first 10.525 GHz RFID microwave transponder fully compatible with traditional and inexpensive DRT-based motion detectors is designed, realized and tested. It is capable of backscattering an artificially generated Doppler wave modulating ID code and sensor data. The appropriateness of the proposed approach has been verified in a telemedicine test case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
