WiFi Sensing systems require more complex algorithms compared to traditional RADAR systems. Additionally, it allows for the exchange of information between multiple devices.

Having a MAC layer present in a RADAR system makes coordination and sharing of air-time resource usage between multiple devices possible. Wi-Fi benefits from having a well-defined Medium access control (MAC) layer entity which is specified in the 802.11 standard.

In comparison with RADAR technology, such as Frequency-modulated continuous-wave radar, WiFi Sensing may use its physical layer (PHY) for both environment measurements as well as digital communication. 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. Ĭombining communication and sensing within mobile networking technology is a large area of exploration, and is sometimes referred to as Joint Communications and radar/radio Sensing (JCAS). There are three major applications: Detection ( binary classification), Recognition ( multi-class classification), and Estimation (quantity values of size, length, angle, distance, etc.). Wi-Fi may operate in multiple frequency bands, each providing a unique range of possible use cases dependent on the physical electro-magnetic propagation properties, approved power levels, and allocated bandwidth. The applications of WiFi Sensing are broad. WiFi Sensing is the combination of Wi-Fi and RADAR sensing technology working in tandem to enable usage of the same Wi-Fi transceiver hardware and RF spectrum for both communication and sensing.

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