Proof-of-Concept for an IoT Sensor Platform with 2.4GHz Wake-up Radio

Abstract

Driving the 4th Industrial Revolution and fueling the Internet of Things are billions of resource-limited devices offering computation, control, and telemetry. Designs aim to save energy yet satisfy real-time service and availability, thus necessitating power solutions. Main components typically stay in sleep modes until a wake-up event occurs, such as a timeout. Communication is often scheduled for these active periods, leaving designs susceptible to idle listening and wasted energy. An attractive approach for energy optimization and sustainability for low-power devices is wake-up radio (WUR) for the ability to wake-up devices over-the-air. This work proposes the system integration of two recent prototypes: a sensor platform for industrial IoT and a 2.4GHz WUR. Preliminary results demonstrate this proof-of-concept.
