Correct. But then you have to have more circuitry from Doppler shift removal.
If you could get all this scheme to work, you’re talking about more sophisticated phones (a billion?).....nope, that’s not a problem...I’m sure Apple is working on the iSat right now.
You don't know what you're talking about.
Doppler shift correction is in every smart phone, in the GPS. It's all software now.
