Keynote I: Understanding and Pushing the Sensing Limits of WiFi/4G/5G Signals

Prof. Daqing Zhang

Peking University and IP Paris

Abstract

WiFi/4G/5G based wireless sensing has attracted a lot of attention from both academia and industry in the last decade. However, fundamental questions such as the sensing limit, sensing boundary and sensing quality of WiFi/4G/5G signals have not been answered, making the wireless sensing system design and deployment in a trial-and-error manner. In this talk, I will first introduce the Fresnel zone model as a generic theoretic basis for device-free and contactless human sensing with WiFi/4G/5G signals. Then we propose to define and deploy the Sensing Signal to Noise Ratio (SSNR) as a new metric to reveal the sensing limit, sensing boundary and sensing signal quality of WiFi/4G/5G-based human sensing systems. We further apply the SSNR metric to show how we can push the sensing range of a commodity WiFi-based human respiration monitoring system to more than 30 meters by exploiting the time, space and frequency diversity of WiFi signals.
