Nano-Power Wake-Up Radio Circuit for Wireless Body Area Networks

We developed, implemented and tested a Nano-power Wake Up Radio mainly intended for Wireless Body Area Networks (WBANs), but it can be also used in other types of low power wireless networks. The radio was tested for power consumption and robustness to communication interferences from a wireless devices commonly found around the person carrying a WBAN. Results show that our radio has significantly lower power consumption when idle listening (470nW) than other state-of-the-art radios. We also developed passive filtering method that can, along with our preamble detection method, significantly reduce power for false wake ups in a WBAN.
