So the requirements are TDD BAND 48 with 1W output power. You need only one cell (20mhz) 2x2 MIMO or you need CA support 20+20mhz (2 cells)? About unlicensed 2.4ghz - which LTE band you are referring? Is it TDD BAND 41? If yes, maybe you could tell more which exact frequency range as the current B3...
