Frequency Jamming patent in the 40's…Heddy Lemar

In 1940, Hedy Lamar, Hollywood star invented the means of secure wireless data transfer, radio jamming, the remote control and the torpedo.

This innovation is the kernel of wireless data communications. Frequency hopping was conceived as a way to keep a signal secure from enemy jamming, but it can also be used to allow multiple signals to share the same spread of spectrum without interference. That's how we can all use our smart phones, tablets, and laptops at the same coffee shop, sharing only one Internet connection. I'm sure it could be done on aircrafts as well….or something completely undetectable.
