Just to make it clear - current "unlicensed" LTE technologies are LTE-U and LAA require an "anchor" channel in a licensed band. I.e. you still can't run it in your home unless you have a license for one other spectrum band. It's still limited to a carrier play, unfortunately. There is MuLTEfire tech by Qualcomm which can supposedly work completely in unlicensed spectrum, but it's proprietary and not very much is known about it so far.
