Surely any drone pirate worth his/her salt would use a CDMA radio?
- StavrosK 7y agoNo, that's too high latency to control the drone reliably after GPS is jammed (and if it's not jammed, the drone will just return to you when it loses signal anyway).
- pinkfoot 7y agoRadio waves, traveling at the speed of light, have too much latency?
- StavrosK 7y agoOh you meant setting up a CDMA base station somewhere, faking a cell tower and controlling the drone that way? I misunderstood, that sounds like a practical and affordable solution that will surely escape detection and be better than a $50 handheld controller.
- MacsHeadroom 7y agoI wouldn't be so certain that setting up a fake cell tower would escape detection. You'd have people triangulating your position and preparing enormous fines as soon as you turned it on, well before controlling a drone with it. Unless you were being sarcastic? It's hard to tell on the internet.
- StavrosK 7y agoI was, yes. You're either using CDMA over the cell network so you can be far away, or you're using a $50 radio that has a 20 KM range itself.
- pinkfoot 7y agoNo, I meant both the controller and drones radio use the CDMA modulation technique to transmit at power levels imperceptibly above the background noise levels. A listener would only hear white noise and would not even know the drone/controller are transmitting. (This is after all what CDMA spread spectrum modulation was invented by Hedy Lamar for) Absolutely nothing to do with the W-CDMA telephone system.
