Earlier quoted context omitted.
CPU design and RF stuff are both very difficult; I wouldn't assume one way or the other. I wonder if knowledge of CPU design is more widely dispersed (e.g. you can hire ex-Intel, ex-AMD, ex-IBM people) than cellular radios where the only (working) ones seem to be made by Qualcomm.
> cellular radios where the only (working) ones seem to be made by Qualcomm. Seems strange, given that plenty of manufacturers are making the radios on the other side of the cellular connection. Can't, say, Ericsson take the radios in their cell towers or picocells, redo their tape-outs for phone scale, and end up with a workable mobile radio?
I suspect those high-power radios are not doing the majority of the RF in silicon.
