Do I need a sprint airave if I have airport extreme?
I already have the airport extreme, and it works ok at handling wireless calling on my iPhone 6. There is still some breakup during calls, but it's way better than the reception I had before. Someone told me the Sprint Airave will boost my cell signal further, but from what I can figure out, it is just another wireless router. Does anyone else have both, and what are your opinions on the airave? Do you have any issues with it? Thanks!
