"A cellphone based on software-defined radio would be lighter, smaller, cheaper, and more power efficient. What's more, it would be better at making calls: instead of being stuck with one frequency or even one cellular carrier, it would automatically search out the best and least expensive way of connecting. And equipment makers wouldn't need to overhaul their products to fit every new telecommunications standard. Wireless providers would be able to roll out new services easily and troubleshoot technical glitches with a simple download.
We aren't there yet, but software-defined radio is definitely coming. Don't expect an overnight transformation, though. After all, it took years for the PC to sweep aside the IBM Selectric typewriter. This revolution, too, is bound to happen in a series of incremental but significant steps."
What about the big Monopolies?
There is so much money behind that I can hardly believe this dream will ever be possible...
