802.11 is inefficient? What are you talking about. It is more efficient than cellular systems in terms of bits/second/Hertz. Unlicensed does not mean inefficient.

Europe is targeting 500 MHz towards the end of this year.

CSMA/CA basically says: hear a few milliseconds if someone else is sending something and if not send yourself - this is a problem with noise and lot's of networks. LTE assigns timeslots and can omit the problems - there are better solutions now than CSMA/CA like OFDMA¹
