Re: USB 3 is a disaster - WiFi and other wireless interference is awful
While concern over issues like this is healthy, I doubt that your fears are founded in this instance.
First of all, the spec is broad ranging, covering everything from the connectors, to the voltages, to the cable composition, which doubtless includes appropriate shielding and grounding. In addition, regulatory bodies, such as the Federal Communications Commission, would seriously frown upon the widespread proliferation of RF jamming technology, even if the jamming was a side effect.
I feel like there may be some use for the inverse of the saying, "If it sounds too good to be true, it probably is."
