“Between now and then a long time,” he said. AT & T announced on Wednesday that it will upgrade its current network faster version, which is about twice the theoretical speed of the connection to the network.

At the same time, he noted that each bit of data that passes over the network in terms of cost, that variable pricing could be an option down the road.
