According to a new project, Wi-Fi devices could quickly become sensors that can collect all sorts of useful information.
The 802.11bf Task Group (TGbf) is committed to leveraging the ubiquitous nature of Wi-Fi to extend its use from communication-only standards to provide enhanced sensing capabilities.
“As Wi-Fi becomes more and more present in public and private spaces, we can take advantage of its ubiquitous nature to breakthroughs such as human presence detection, activity recognition, and object tracking, to name a few. It’s natural to implement wireless sensing applications. ” Francesco Restusia, an assistant professor of electrical and computer engineering at Northeastern University, states in a treatise.

Wi-Fi as a sensor
Restuccia’s treatise summarizes the status of the WLAN sensing project currently being developed by the Institute of Electrical and Electronics Engineers (IEEE).
This project aims to utilize WLAN signals to detect various characteristics of a target of interest in a particular environment. According to the project, we want to measure details such as range and speed, detect movement, presence, and proximity, and be sensitive enough to distinguish between objects, people, and animals.
Once complete, WLAN sensing should work in rooms, homes, cars, and corporate environments. The sensing feature is applicable to many IEEE 802.11 standards.
“So far, R & D efforts have focused on improving the accuracy of classification of monitored phenomena with little consideration of S & P. [security and privacy] Restuccia writes in her treatise, as reported as “problems.” Register.. She adds that these issues need to be addressed in order for people to trust the new standards.
