T-Mobile's USA Chief Network Officer Neville Ray seems to think 4G networks are just not important, but if T-Mobile were do have to choose, they'd pick LTE.
We'll look towards LTE at the right point in time for us. That ecosystem is going to be much richer than the competing one from WiMax, which is really a niche play.
Fourth-generation networks promise average download speeds of about 10 megabits per second, compared with 1.7 megabits per second for 3G.
For why Ray thinks this way, follow the break.
