3.45GHz Auction Results Sat, Jan 15, 2022

On Friday, the FCC posted the results from Auction 110. On Saturday we updated the January 2021 release of our Mobile Carrier - Spectrum Ownership Analysis Tool to reflect the auction results. These results provide the most detailed view of each carrier's spectrum that can be deployed for 5G, particularly all of the available upper mid-band spectrum including EBS/BRS, 3.45GHz, CBRS, and C-band.

In the Spectrum Grid, we can see the channel allocations. In general, Dish took the upper end of the band with T-Mobile and AT&T alternate having the lower parts of the band. In many markets, AT&T is pinned in the middle of the band between T-Mobile, Grain, and Columbia Capital. Each of the spectrum investors has selected spectrum assignments adjacent to AT&T's spectrum meaning they are each well positioned to sell to AT&T if the 3.45GHz spectrum cap is lifted.

In the National Band Ownership slides we look at each carrier's ownership based upon the percent of MHz-POPs that they control.

For the 3.45GHz band, AT&T leads the way with 39% of the MHz-POPs, Dish has 30%, T-Mobile has 12%, and USCellular has 4%.

Looking the the complete picture for Upper Mid-band spectrum, T-Mobile still leads with 34%, Verizon follows with 30%, then AT&T with 24%. Dish has 9% of the upper mid-band MHz-POPs and USCellular has 2%.

Sub-6 GHz Spectrum Screen including 3.45GHz allocation Thu, Apr 08, 2021

Last year we provided an FCC Spectrum Screen Analysis reflecting the effects of the EBS reconfiguration, the CBRS allocation, and the C-band allocation. Two weeks ago the FCC has revised the Sub-6 GHz spectrum screen through their 3.45GHz rulemaking.

In the chart below we reflect the spectrum depth allotments that are included in our Mobile Carrier - Spectrum Ownership Analysis Tool. The links under in the frequency column will open the FCC spectrum screen documents and the comment field indicates the paragraphs where the spectrum screen is discussed.

The Allnet Spectrum Depth column indicates the spectrum allocations that we use in all of our typical spectrum depth reporting (county, CMA, PEA, State, and National). The FCC / Allnet Spectrum Screen allocations reflect the allocations that we use in our County, CMA market, and PEA Market Spectrum Screen columns.

Band	Frequency	Allnet Spectrum Depth	FCC / Allnet Spectrum Screen	Comments
Low Band	600 MHz	70	70
Low Band	700 MHz	90	70	First Net Spectrum not included
Low Band	Cellular	50	50
Low Band	SMR	14	14
Lw Mid Band	PCS	140	140	Includes H-block
Lw Mid Band	AWS-1	90	90
Lw Mid Band	AWS-3	65	65
Lw Mid Band	AWS-4	40	40
Up Mid Band	WCS	30	20
Up Mid Band	BRS	77.5	67.5	BRS1 and BRS K guard bands not included
Up Mid Band	EBS	116.5	116.5	Paragraph 98-100
Up Mid Band	3.45GHz	100	100	Paragraph 101
Up Mid Band	CBRS	0	0	Paragraph 107
Up Mid Band	C-Band	280	280	Paragraph 83
Total MHz		1163	1123

To determine the overall Spectrum Screen value, the FCC divides the spectrum screen allotment (1123) by 3 and rounds to the nearest 10MHz. This makes the new spectrum screen including the 100MHz of 3.45GHz spectrum, 370 MHz.

In the Mobile Carrier - Spectrum Ownership Analysis Tool we have three views into the Spectrum Screen. They are a County Analysis View, a Cellular Market Area (CMA) View, and a Partial Economic Area (PEA) View.

County Analysis View:

In this view, each of the national carriers spectrum screen values are displayed along with the amount of spectrum in that county controlled by the FCC. The FCC value predominately represents the 3.45GHz spectrum allocation, but there is some EBS spectrum (whitespace) that is also allocated to the FCC.

PEA Market Analysis View:

3.45GHz Band Update Tue, Apr 06, 2021

The FCC announced the final rules for the new 3.45GHz band on March 19, 2021. With our April 2021 release, we updated our Mobile Carrier - Spectrum Ownership Analysis Tool to include the 3.45GHz frequency band in each of the analysis modules. The 10 - 10MHz channels appear in our Spectrum Grid as a part of NR Band 77. In the image below, we highlight the FCC's ownership of each of the channels (pre-auction) by county.

Honolulu County has a NA (Not Available) code for both the 3.45GHz spectrum and the C-band spectrum since neither band in available in Hawaii, Alaska, Puerto Rico, American Samoa, Northern Mariana Islands, Virgin Islands, and Puerto Rico. Looking at the National Band Ownership Charts, we can see that this unavailability affects 2% of the MHz-POPs or 2% of the US Population (~6.6M).

In the County Analysis Module the spectrum depth values for eight selected carriers are displayed. This image highlights each carriers 3.45GHz, CBRS, and C-band holdings.
