This Christmas I'm buying a couple people remote controlled quadcopters. Then it hits me. Is there a possibility that the different remote controllers will crosstalk and wind up controlling a robot that it is not meant to control?
How do electronic engineers ensure that electronic toys will be controlled over via one remote controller and not the other?
each RF circuit is only tuned to listen to a single frequency, but how to create so many variants of the circuits?
each quadcopter has a unique identifier and is sent through the wireless controller before each instruction so that the receiver can identify signal through only one set of controller
