Fake news. Posted many, many times on FR and debunked. Why do you post this crap?
Not debunked, to me anyway. And I’m an EE, specialized in digital design. I read the makn article, and it certainly is plausable.
I have het to see anyone with actual EE knowledge explain why it isn’t possible. It most definitely is.
AND I’ll bet it’s in plenty of routers, too.
