You mean the RF circuitry has to continue working in the frequency of the current network and switch frequencies to scan for other networks in all bands simultabeously? I don't think consumer hardware is capable of that. It usually will send probes or listen passively for some time in a band before moving to the next one sequentially. It's an expensive operation.

- sitkack 2y agoIt is more insidious to scan all the SSIDs within the RF sightline of a device than it is to install a GNSS receiver in the laptop. It means that not only do they get all the SSIDs but that they have also triangulated some of those SSIDs. You are also giving up the location privacy of everything you can see.
