I know nothing of this stuff but potentially:
- Extreme wide spectrum frequency hopping. Hard to distinguish from the noise floor.
- Steganographic encrypted channel over fake unencrypted channel.
If course when in doubt, assuming stupidity is the safe bet.
- oneplane 5y agoWhile I haven't dug deep in to the black arts that is RF and MW, it would indeed hide it better (the hopping), but because the noise floor would have 'more energy' during an active transmitter they would either always have to be transmitting or be so close to each other that they can keep the energy low. I think the analysis appliances are capable of finding hopping transmissions, even in the lower range (still expensive) spectrum analysers. It does of course depend on how fast they can scan the whole range and how wide the range is. But Hanlon's razor applies, and indeed, it is more likely incompetence.
