Scientists have figured out how to identify people in a building by using artificial intelligence to analyse WiFi signals. A team at Carnegie Mellon University developed a deep neural network to ...

We’re all walking around in a soup of Wi-Fi signals, but researchers say they can be put to another use—counting people. When people cross the path of a Wi-Fi signal, it weakens somewhat. That effect ...

Researchers in UC Santa Barbara professor Yasamin Mostofi’s lab have enabled, for the first time, counting a stationary seated crowd using WiFi signals, and without relying on people to carry a device ...
