Our most recent posts have looked at the low band spectrum that T-Mobile is accumulating, the 700 MHz A-Block.  To see the low band spectrum that AT&T has typically deployed for LTE, we need to look at the 700 MHz B-block and 700 MHz C-block.  With the B-block spectrum, it is clear that AT&T is visually the dominant spectrum holder.  When looking at the licensed population data, this is true as well.

AT&T dominates the licensed population (POPS) numbers as well, accounting for 274 million of the 312 million US States and Territories population.  These population numbers relate to the 2010 Census.  C Spire with 1.4 million licensed POPS and US Cellular (23 million) both have significant spectrum in their regional operations area with the 700 MHz B Block spectrum.

With the C-block spectrum, AT&T dominates the west coast and southeast but gives way to USCellular and other regional operators in the midwest.

Looking at the licensed population numbers, AT&T has about 15 million more licensed POPS with their C block spectrum than their B block spectrum.  While USCellular has significantly less C block spectrum (6.8 million POPS compared to 22 million POPS).  It is also apparent that T-Mobile has very limited ownership of B-block spectrum (262,000 POPS) and C-block spectrum (119,000 POPS).  Clearly AT&T has the ability to combine their B and C block channels in many markets to create a 10x10 LTE channel.  We will include a map in a future blog detailing AT&T's total 700 MHz (A/B/C) spectrum holdings as well as USCellular's total 700 MHz (A/B/C) spectrum holdings.

700 MHz A-Block Spectrum Owners January 19, 2016 11:30

T-Mobile has increased their ownership of low band spectrum licenses to cover over 200 million POPs (population).  The map above depicts the 700MHz A-Block spectrum owner for each US county.  From the map you can see that significant portions of the 700 MHz A-Block spectrum are controlled by parties that are not likely to sell, like US Cellular and C Spire.  Cavalier and Charter are signficant (land mass) spectrum holders that would be likely sellers to T-Mobile.
Below you can see the population counts for each of the owners.  After T-Mobile's 201 million, Cavalier covers 26 million POPs, US Cellular 35 million POPs, C Spire 14 million POPs, Continuum 14 million POPs, and Laser has 10 million POPs in Chicago.
