The problem is the time division duplex nature of the signal. They are also separated by frequency for up and down. The phones are TDD as well as FDD. You would have to have something to sync the amp and switch its direction in sync with the cell tower.

Anyways I am thinking of testing it my LTE 2.1/1.7 Ghz phone and see if works as off air repeater...what are your thoughts Hobson?
