I'm not sure I understand. I didn't see anything in the article that says that Inmarsat's technology replaces local data and voice logging with wireless connection
I mean to suggest that would be like saying cloud based storage can totally replace RAM and hard drive.
I'm assuming Inmarsat's product goal is something that integrates voice and data logging with satellite connections which could have some definite benefits... and some extra costs and maybe some unintended consequences.
The use of the words in the Guardian article like "obsolete" and "game changer" to describe this seem more like marketing types running amok.
I mean why should an airline want this?
...and I'm afraid of the real answer....
