We propose an ultra high frequency (UHF) radio frequency identification (RFID. 902–928 MHz in the US) channel emulation testbed that is capable of simultaneously emulating unique wireless channels. The proposed system can potentially be an invaluable tool in the design and validation of RFID-based Internet of Things (IoT) sensors and systems. Emulation of ray-tracing-based wire... https://www.ealisboa.com/
