Similar job to what one of my friends did over pinephones firmware.
@PawelK Just to be clear, I didn't take part in the Cellular Modem Reverse Engineering work. I was invited to work on it but it's a Felony in my country thanks to the FCC.
I did Reverse Engineering work on the BL602, FCC regulations aren't as strict for this, and worked alongside Mr.Lee.
@AmpBenzScientist
Yeah it was bl602 on your side. My bad. I think the german dude worked on a modem part if I remember correctly. I wonder what law says about revving modem fw within cee. Russia and China are much safer locations for reversing restricted codes.
Does the us law make distinction between bt+wifi vs cellular comms terminal code revving? That sounds weird.
@PawelK Cellular networks are part of our infrastructure and the goal of the FCC is to prevent interference. The wavelengths used for cellular travel farther than 2.4GHz. The cellular wavelengths are closer to some military wavelengths. The Modems are SDR so they can quickly adapt to different wavelengths. It's not unfeasible that a cellular modem could cause interference on some of these wavelengths.
I've met Federal Agents before and I live close to a large Air Force Base. I've heard of kids launching model rockets within range. They and their families got free trips in the back of white vans to get questioned.
