Quote: How will the new 802.11bf Wi-Fi standard work?

The current proposal of this next-gen sensing technology is divided into two parts: using low-frequency waves (1GHz to 7.125GHz) to sense motion within a large space like a room, and using high-frequency waves (45GHz and above) to sense movements at short range — like recognizing your gestures when you’re sat in front of a laptop or your phone.

The protocol also wants to standardize the interface, so that different Wi-Fi components in the house can ‘talk’ to each other. This will solve the problem
