> Drones also operate in a cluttered segment of the electromagnetic spectrum. First-person view drones use unencrypted analog radio signals, and in hot parts of the front, as many as a dozen drone teams may be competing for use of a handful of frequencies (a consequence of using cheaper components). This results in the need for sophisticated de-confliction procedures that, quite simply, do not always work. Even when de-confliction works, sometimes a team must wait as long as half an hour for a frequency to become available before takeoff. If it does not work and two drones find themselves in the air on the same channel at the same time, they will interfere with each other’s signals, usually resulting in a crash. On top of that, the enemy’s drones also fly on the same frequencies, which can also result in interference and a crash.
This gave me the somewhat macabre image of Ukrainian and Russian drones doing automated frequency coordination with each other, so they can orderly proceed in bombing each other's soldiers.
I don't think that's what happens though. But I'm surprised flying drones in the same area as enemy operators is even possible. Wouldn't both sides try to jam or take over each other's signals, deliberately blocking channels, etc - so that in the end, no one could control anything?
Or, if the signals are really unencrypted, what keeps anyone from setting up a radio beacon that just spams the "detonate now" signal on all channels at maximum power. Instant drone-free zone?
