    LTE-U vs LAA

    My limited understanding of LTE-U vs LAA is that LTE-U can operate as a stand-alone LTE signal but LAA has more collision avoidance and must be used in conjunction with licensed spectrum. LTE-U was standardized as bands 252 & 255 but is now obsolete and has never been implemented in any phones. LAA is band 46 and is commonly found on higher tier phones of the last few years.

    Would I be correct in concluding that someone could not legally set up a tiny unlicensed private LTE system based on LTE-U, simply because no phones support the standard and LAA (band 46) requires the use of licensed spectrum as a base? I'm wondering if there's a way that ship or airplane operators could legally operate cellular systems on unlicensed spectrum in-country and make big bucks from high roaming fees.

    Whether its airlines .. or Cruise Ships, they could both perform this in international space/waters. The interesting part would be ... what country code ? On similar note, would they have to just 'disable' service in certain airspace/coastal regions when they change countries ?
    For airlines, WiFi is simpler to set up, and can implement roaming (usage) deals with carriers for access. Eg. Delta was $50/flight, but T-Mobile's perks made it free.
    AT&T... your world, throttled.

    The point is, why disable the ship's cellular system if it's running in unlicensed (license-free) spectrum? You can create your own little cellular bubble, all perfectly legal. Think of all the extra revenue at $6/min and $15/MB.
