Radio 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.
