We covered T-Mobile's 4G LTE launch and Uncarrier event pretty closely. At the time, all of the other major networks in the country already had operating LTE networks in multiple markets. T-Mobile now believes that it could end up being the first carrier to roll out 5G LTE-Advanced.
In a recent interview with Venture Beat, T-Mobile's head of radio network and evolution strategy, Yasmin Karimli, said that this is due to their slow rollout of 4G:
I think we'll probably be able to move faster [to LTE-Advanced] because we have the latest hardware in place. Others may have hardware that's two years old, so they may have to rip and replace.
We don't fully know what it will take for the other networks to roll out 5G LTE-Advanced, though what Karimli says makes sense. 5G LTE allows for theoretical speeds of up to 300Mbps, around three times faster than LTE. T-Mobile plans to cover 100 million people by mid-2013 and 200 million by the end of 2013 with 4G LTE.
