There are very few violations of the FCC&#x27;s rules in general partly because the FCC regulates and certifies hardware manufacturers of radio equipment, so it&#x27;s very difficult to purchase equipment that doesn&#x27;t follow the rules. You can see this happening in the Wifi space where the FCC is clamping down on dd-wrt at the device manufacturer level because the software allows people to violate that frequency&#x27;s rules. People with the right skills can build custom equipment to violate the rules but it&#x27;s rare. And for the few people that do try to do things like pirate radio the FCC hunts them down and the penalties are stiff.<p>My point being that for the most part the FCC&#x27;s regulatory scheme works at keeping people playing by the rules without extra layers of technically complicated security.
