Performance analysis and measurement results of an ultra-low power wakeup radio in the presence of interference

Wakeup radios (also referred to as event-driven radios) is a paradigm for low-cost, low-energy identification radios to assist the main radio for continuous channel monitoring without sacrificing the latency requirements. Wakeup radios show the potential to extend considerably the life-time of the main radios. In this paper, we present the design, and measurement results of an ultra low-power wakeup radio. The designed wakeup radio achieves excellent performance in terms of probability of miss-detection and probability of false alarm. The designed radio is also analyzed in the presence of co-channel continuous wave and modulated interferer in a wide variety of deployment scenarios. The performance is considerably better than other low-power implementations available in the market.
