It is designed to exploit the LoRa modulation based on chirp spread spectrum and is inherently less susceptible to false wakeups caused by interfering signals. The theory of the concept is presented indicating key parameters. For validation, a proof-ofconcept implementation is developed with exemplary measurement results.enChirp spread spectruminternet of things (IoT)LoRawake-up receiver (WuRx)Natural Sciences and Mathematics::537: Electricity and ElectronicsTechnology::600: TechnologyA novel concept for a wake-up receiver for LoRa communication with improved selectivityConference Paper10.23919/MIKON66970.2026.11577827
