That's just my take on it.
Drones change altitude, speed and position faster than ADS-B updates... `every second` needs to be every tenth of a second or faster before it becomes relevant for drones.
Some kind of electronic barrier is pie-in-the-sky thinking which could have implications for a myriad of electronic devices that rely on real-time live connection - like cell phones, laptops, medical devices and of course, the internet.
