Have you ever wondered what frequencies were being used by different providers? It’s all strictly regulated by the FCC… if anything is being broadcast. That’s the reason your cell phone signal doesn’t interfere with your TV signal. In some cases though, the FCC has put two different things on the same frequencies, like cell phones and Wi-Fi. In those cases the signals are usually digital so they can more easily keep from causing interference with each other.
On the other hand, if the information is only going through wires and not through the air, there’s practically no regulation. That’s why DIRECTV coax networking signals take up the same frequencies as television, and that’s why you can’t diplex if you’re using coax networking.
Here’s a handy chart that lets you see the different frequencies in use:
