In its Q4 2012 results, T-Mobile had some interesting notes on the deployment of its LTE network -- mainly that the network is now "completed" in both Las Vegas and Kansas City, Missouri. The network rollout has now apparently been accelerated, and T-Mobile is projecting it will reach 100 million people with LTE by mid-2013, with more than 200 million being covered by the end of this year. Las Vegas and Kansas City are great test locations, but with these lofty projections they're going to have to light up LTE in the big population centers quickly as well.
Additionally, T-Mobile took time to tout some numbers about its current HSPA+ footprint. Several new areas are moving to 1900MHz today, including Orlando, FL and Richmond, VA. The carrier states that 225 million people are now covered with its HSPA+ service, with 144 million being covered by the new 1900MHz service. These two rollouts go hand-in-hand, as T-Mobile will need the AWS (1700/2100MHz) spectrum freed up by the HSPA+ move to 1900MHz in order to completely roll out LTE.
It comes as a bit of a surprise that T-Mobile has fully completed two city-wide networks before a single consumer device with LTE has even been announced, but it's good to see that the network is being built out quickly in anticipation of a launch. Current rumor pegs March 27th for the launch of several LTE-enabled devices on the network, and hopefully T-Mobile will have more cities to announce at that time as well.
