T-Mobile Low Band Spectrum Depth January 12, 2016 11:00
T-Mobile was quite active during the last quarter of 2015 closing deals to acquire low band (700 MHz A and B Block) spectrum. Green areas in the map above reflect areas where T-Mobile controls 12 MHz of spectrum providing for a 5x5 LTE channel. The Blue areas in North Dakota reflect T-Mobile ownership of both the A and B block, enabling the deployment of a 10x10 LTE channel. Below are the transactions that were announced during this time period:
It should be noted that during this same time period, T-Mobile assigned their 700 MHz A-Block spectrum in Alaska to Alaska Wireless Networks. T-Mobile had acquired this spectrum from Triad 700 in late 2014.
Using the 2010 Census Population for each of the US Counties, it can be seen that T-Mobile has over 200 million licensed pops (Population) where they have enough spectrum for a 5x5 low band channel, and 10 thousand pops where they have enough spectrum for a 10x10 low band channel. The 2010 Census set the total US population (states, districts, and territories) at 312 million.
