With just $800 in basic equipment, researchers found a stunning variety of data—including thousands of T-Mobile users’ calls and texts and even US military communications—sent by satellites unencrypted.

They still use energy, no? To relay signals on another frequency. That should come from somewhere, and also the more different signals, the more noise. And without their input frequency being regulated, there must be lots of noise.

    You can do this same attack on any antenna, noise can't be protocolled away. Repeating both signal and noise is a downside to bent-pipe setups.

    Input frequencies are regulated via band-pass filters.

    I'm not talking about technical things, just that IRL on regulated frequencies one can do something because people using it for bullshit are legally prosecuted. Depends on wavelength, of course.

    But OK, now I think I get what you are talking about.
