In Oblivion, the Tet orbits the earth, and communicates with the towers with imposed regular transmission cutoff as a simple consequence of the Tet's being out of reach of direct radio communication.
- First, this structure is massive, masters space travel, advanced genomics, fusion, and very advanced technology (drone propulsion, energetic weapons...). We can safely assume that it masters radiocommunication subtleties.
- Second, it seems totally capable and willing to build or send gigantic structure called Tower all over the earth.
- And it spends a lot of energy fighting the remnants of humanity through these drones that must be constantly repaired by cloned that themselves must be constantly controlled for any "inefficience".
So at first: why aren't the Towers providing a real communication network? Or why aren't some thin satellite constellations orbiting the earth to ensure such a dramatical strategic facility? This is more important if you consider that drones can't move without direct connection with the Tet (as at the end of the film, the Tet's destruction instantly shuts down power to an army of drones)... This last fact raises so much more questions on other very questionable technological choices from such a powerful being.
Is there a way to explain this seemingly self-imposed lack of stable communication? Might it serve a purpose? Did I miss critical information that would help enlighten me?
