Can it reduce the time spent at airports
And getting to/from airports?
This will be more than the flight time at each end.

It seems you don't understand what SDR is.
In practice mobile phones use it.
SDR produces the baseband signal via a DAC which, in the case of mobile that i was involved with, there is a device known as the RFIC whose output chain is composed of primarily a DAC, RF oscillator and the mixer to modulate the carrier.
An external RF power amplifier and filters complete the transmit chain.
One of the big contract electronics manufacturer (Celestica) got started when IBM built the world most automated laptop manufacturing plant and lost money on the laptops because there were so many managers involved.
They sold it to a group of managers who set up Celestica and sold the laptops at a good price then began to expand.
I worked for Celestica starting in '99 on production test for an IBM product.
