SDR for LTE

Image above shows a Mobile Phone with and without SDR

Since LTE will have highly flexible bandwidth and it would be possible to use phones in many different bands with facility for reprogramming if the operator you are using your phone with has completely different frequency band it is being proposed that Software Defined Radio (SDR) be used with LTE.

I am not aware as of now a practical mobile device with SDR so this would be an interesting leap if adopted by the mobile manufacturers.
