I just need to scan the range of frequencies related to WiFi (both 2.4GHz and 5GHz) and decide which channels are busy and which are not. It's like a special WiFi Channel Scanner, only that we will also take into account non-WiFi signals. So the solution will probably not need to "fully decode" the signals, especially if it's clear that the hardware cannot handle it. Is such a solution possible?
