I got a little lost reading this but think I got the gist of it; blame it on the Chinese instead of the Cubans.Likely solved: IM distortion
He discussed the AP clip with his frequent collaborator, Wenyuan Xu, a professor at Zhejiang University, in Hangzhou, China, and her Ph.D. student Chen Yan. “We saw it as an interesting puzzle,” says Xu, whose lab works on embedded security, including the use of ultrasound and radio waves to fool voice-recognition systems and self-driving cars. “It was a lot of fun to try to solve it.”
Knowing how easy it is to create IM distortion, I'm about 99.99% certain this was just poor engineering on the part of the Cubans.Interesting. I’ve a hard time believing it was an accidental thing. Just paranoid I guess.
What would the two devices be and why were they in there, anyway?Knowing how easy it is to create IM distortion, I'm about 99.99% certain this was just poor engineering on the part of the Cubans.
They could be almost anything - broadcast radio, modern convenience devices (voice activate this, phone active that) - anything that's not using infrared to communicate is almost certainly using radio frequencies. It could even be as simple as a live wireless microphone in a conference room stepping on a cell tower's signal nearby (something which is heavily regulated by the FCC in the US).What would the two devices be and why were they in there, anyway?
Seems like it would happen a lot more frequently, then...They could be almost anything - broadcast radio, modern convenience devices (voice activate this, phone active that) - anything that's not using infrared to communicate is almost certainly using radio frequencies.
