Verizon St Louis Spectrum Purchase, Carrier Aggregation, and Competitive Landscape November 6, 2013 09:26
It is interesting to look at the details of Verizon's spectrum purchase from US Cellular in the St Louis market area (EA-96). Many industry sources talk about how purchase will provide 20MHz for Verizon's LTE. While this is true, it should not be confused with Verizon deploying a 20 x 20 channel. As can be seen from the Spectrum Grid view of AllNet Labs' Spectrum Ownership Analysis Tool, Verizon is purchasing the AWS B channel and previously owned the F channel. Although Verizon will own 20 MHz of spectrum, it is not contiguous and until they can deploy Release 12 software code into their network, they will have to operate this spectrum as two separate 10 MHz channels. Release 12 is likely a 2015 or maybe 2016 release since operators are either planning or deploying Release 10 currently.
The industry talks alot about Carrier Aggregation (CA) but there are several facts that are not well understood. First, Release 10 includes the functionality for carrier aggregation but the frequency band definitions for the US are not included until Release 11. Another point that needs to be understood is that the initial definitions require that aggregated carriers be in contiguous blocks in different spectrum bands (inter-band) or in separate blocks but in the same band (intra-band). For Release 11, only 2 carriers can be aggregated together. For Release 12, Verizon has sponsored a work group that will allow 3 carriers to be aggregated, 1 from the 700MHz band and 2 different carriers from the AWS band. Thus, Release 12 will be necessary for Verizon to aggregate their two AWS blocks of spectrum with their 700 MHz LTE.
The Spectrum Grid view is sorted by the EA geographical area which show that the AWS B and C licenses have not be dis-aggregated. The A channel licenses do show discontinuity since they were originally auctioned as CMA licenses. AT&T through their Leap purchase will strengthen their AWS ownership in this market.
To look at the competitive picture for spectrum in the St Louis market (EA-96) we can look at the
Company By Band worksheet from the AllNet Labs' Spectrum Ownership Analysis Tool. Looking first at Verizon, we can see the variety of spectrum depths across the EA that Verizon indicated in their FCC filing. Verizon will range from 62 MHz to 117 MHz depending on the county. The only county that Verizon controls 117 MHz is Montgomery County, MO which is 40 miles west of St. Louis.
Looking at the other carriers in this market we see that US Cellular will still control between 32 MHz and 69 MHz, while AT&T with their Leap purchase will control between 61 MHz and 105 MHz.
T-Mobile controls between 40 MHz and 60 MHz with two counties at 70 MHz and Sprint with their Clearwire purchase controls between 130 MHz and 242 MHz.
