RF monitoring

Do some Digi`s embedded modules (any) with Wifi 2,4Ghz, 802.11 interface support RF monitoring or RF monitor?

Nothing that I am aware of, but I bet if you asked their Etherios Wireless design group to do so they could modify the newest WiFI XB to do so…

Digi devices dont have RF monitor support.
