Hmm. The article appears to conflate multiple things?
One of them is “viewing” the RF spectrum to build up an image. The other is reading the unencrypted beamforming data from a router. That second one depends on people carrying a WiFi-capable piece of electronics with them doesn’t it? There has to be something for the beam to focus on, some sort of beacon signal.
Although I guess all it really needs is for the person to step between the router and a device connected to the router; that should enable analysis of the disruption patterns.
I don't think a person has to carry anything. The tracking is based on measuring the interference a moving person (or a dog) creates between the router and a connected device like a range extender or a networked printer.
