I guess I was thinking more in line with SDR or foss hardware and not using Qualcomm at all. I need to do a deep dive, but it looks like there's a couple FOSS 4g LTE and 5g modems around - maybe running a soft phone and personal voip setup would bypass a lot of the security concerns.
It sucks that any time you start to inspect almost any tech, there are assholes trying to exploit every last bit of data and microamp of processing power to screw you in some way.
- marcan_42 5y agoSDRs are for research and base stations. Trying to do a mobile phone based on an SDR stack would eat through your battery in minutes. You need dedicated silicon.
- userbinator 5y agoI believe mobile radios are effectively narrowband SDRs, optimised for the application. Hence the concerns around firmware and FCC certification.
- marcan_42 5y agoKind of, but they are built around DSP architectures with dedicated hardware accelerator blocks. It's not the same thing as GNURadio. Base stations are often built out of more generic SDR tech, and those do chew power like crazy.
