WiFi Sensing: What is it and how does it benefit us?

Wifi is ubiquitous and it has been since its launch in 1997. We are always connected whether we know it or not. From our homes to offices, from the streets to high skies there is wi-fi everywhere.

So the question is, if we are so connected and there is data everywhere how can we leverage it?


WiFi Sensing (also referred to as WLAN Sensing[1]) uses existing Wi-Fi signals to detect events or changes such as motion, gesture recognition, and biometric measurement (e.g. breathing).[2][3]

WiFi Sensing uses a short-range passive radar technology, which allows wi-fi and radar sensing technology to work in tandem for both communication and sensing. Combining the two technologies can leverage existing hardware and infrastructure, enable new services, and provide a higher level of interaction with networked devices (e.g. IoT and automation).

Simply put, WiFi sensing uses WiFi to detect and interpret presence and motion.

Benefits of WiFi Sensing

WiFi Sensing has proven to have many benefits and use cases that help improve our everyday lives. With WiFi Sensing still being a relatively new technology, we have seen so many possibilities of what it can do to leverage to phenomenon of smart devices all around us.

So, let’s breakdown the benefits of this wonderful technology.

Omni Directional

WiFi is able to pass through walls, which allows it to collect data from 360 degrees. Traditional sensors are limited to the direct periphery which highly limits the amount of data it can capture.

WiFi Sensing enables out of line-of-sight (LOS) detection increasing the accuracy and area in which motion is sensed and detected.

Ability to leverage existing technology

WiFi Sensing does not require any extra hardware and it is easily integrated into existing technologies. Other forms of radars typically require dedicated devices which can be costly and complex.

WiFi Sensing allows you to leverage existing devices to integrate and optimize.

Privacy and Surface Coverage

WiFi sensing can cover larger surface areas than traditional radar and other forms of sensing technology. WiFi sensing also does not capture personal data, which makes it less of a threat to its competing technology.

The increase in coverage, as well as increased privacy makes it largely beneficial for many consumers.

The New Standard

With the proven benefits of WiFi Sensing technology, the IEEE (Institute of Electrical and Electronics Engineers) has unveiled that it is creating a new standard but it isn't for communication - it's for sensing. The upcoming 802.11 standard will unlock endless possibilities for the entire industry.

This new standard only further validates the future and power of WiFi Sensing.
