Does Fingbox support all Wi-Fi bands?
Fingbox supports all Wi-Fi bands. The DigitalFence feature Fingbox has a dedicated 2.4Ghz Wi-Fi interface.
In the majority of cases, Wi-Fi enabled devices to keep probing periodically the 2.4Ghz spectrum even when they are connected to a Wi-Fi with 5Ghz channels only. So Fingbox detects almost all of devices even on 5Ghz channels.
If devices are not connected at all to a Wi-Fi network, but they have Wi-Fi option enabled, Fingbox will always detect them.
What’s more is that a number of non-trivial mobile devices nowadays are periodically probing Wi-Fi as part of mobile phone location services, even when the Wi-Fi option is disabled by the user, so they are detected anyways by Digital Fence.
