The Wireless Broadband Alliance (WBA) is taking the idea of detecting objects using WiFi signals very seriously. The wireless standards group has just published its ‘WiFi Sensing – Deployment Guidelines’ document which details a technological framework for residential applications, for the first time. Manipulating WiFi signals for sensing objects was conceptualized about a decade ago in academic circles. The first proof of concept product with motion detection algorithms then arrived in 2017, from Cognitive. Two years after that, Israeli WiFi chipset maker Celeno launched an eyebrow-raising offering in 2019 to replace physical cameras and sensors with WiFi-based monitoring for home security and even TV personalization purposes. Home security is the main thrust of WiFi sensing and represents the most rational…
