Exploiting pervasive leaked EM signals for communication, charging and sensing

Since the first successful wireless transmission across the Bristol Channel in 1897, wireless technologies have revolutionized the way we live, work and interact with the world. Besides the traditional communication function (e.g., Wi-Fi), wireless signals are further utilized for other functions such as localization, sensing and even charging. While promising in many aspects, one critical issue associated with these new functions is that they require dedicated signal transmissions, which interfere the original communication function. Take popular Wi-Fi sensing as the example. 200-1000 dedicated Wi-Fi packets per second need to be transmitted to enable Wi-Fi sensing which significantly decrease the throughput of ongoing Wi-Fi communication.
