Wi-Fi signals can be used to count people in a crowd

Researchers from University of California-Santa Barbara have shown that wireless signals can do more than just providing internet access.

[…]By developing a probabilistic mathematical framework based on these two key phenomena, the researchers have then proposed a way of estimating the number of people walking in the space.

The ability to estimate the number of people in a given space could be used in smart homes and buildings, so air conditioning and heating could be adjusted according to the level of occupancy.
