Viewing CBRS Licenses and Call Signs Mon, Mar 29, 2021

On March 15th, the FCC granted the first CBRS PAL licenses to 222 carriers.  In total the FCC issued nearly 17,500 PAL licenses in this initial group.  To view these licenses in our Web Spectrum Viewer, choose our Upper Mid-band (Up-Mid Band) in the band menu and chose the CBRS in the sub-band menu.


To find PAL licenses for specific markets, use our geographic filters.  To find call signs for the Dallas/Fort Worth market, chose CMA Name in the Region menu and start typing Dallas in the Regional Values menu.


In this view you can see the PAL licenses that each carrier controls for each county in the Dallas/Fort Worth CMA market.  From this view there are two ways to view the call sign for each license.  The first way is to click on the spectrum grid cell to reveal the call sign details for that cell.  The detail below is for the CBRS-A channel that Charter controls in Dallas county.

The second way to reveal the call signs puts the call signs into each of the spectrum grid cells, by selecting call signs in the Data Type menu.  This view allows the user to see all of the call signs for the Dallas/Fort Worth market and also indicates the licenses that have not been granted yet, because our placeholder call signs (CBR_C48221_A) are still present.

Mexico 3.5GHz Spectrum - Additional Reconfiguration Tue, Feb 02, 2021

Back in May 2020, we wrote about a reconfiguration of Mexico's 3.5GHz spectrum band to provide AT&T and Telcel with 50MHz of contiguous spectrum in exchange for the 2x25MHz paired spectrum blocks they previous controlled.  At the time Axtel still owned 2x25MHz paired spectrum blocks as seen below.
In July 2020,  Telcel announced their purchase of Axtel's 3.5GHz spectrum which kicked off an ITF (Instituto Federal De Telecommunicaciones) process to combine these spectrum licenses into another 50MHz block.  This move would appear to finish the transformation of Mexico's 3.5GHz band from FDD operation to TDD operation for 5G.  This also consolidates Telcel's spectrum into a contiguous 100MHz block and it delineated available spectrum for a future auction, where we would expect AT&T to be an active bidder to equalize their 3.5GHz spectrum position with Telcel.
In the chart below, we look at the frequency band ownership percentages (in terms of MHz-POPs) for the 3.5GHz band where AT&T owns 16.7%, Telcel owns 33.3%, and ITF still controls 50% of the band.

EBS Whitespace Auction Opportunities Tool Sun, Jan 24, 2021

What is EBS Spectrum?


Educational Broadband Service (EBS) is part of the US 2.5GHz spectrum allocation along with the Broadband Radio Service (BRS). These two types of spectrum fall between 2495MHz and 2690MHz on the 2.5GHz band allocation.

EBS spectrum has traditionally been owned by educators, including colleges, universities, K-12 school districts, and para-church organizations. Originally, the EBS and BRS spectrum licensees were assigned 35-mile licensing circles around a set of coordinates representing the original broadcasting site. In 2009, the Federal Communications Commission (FCC) held an auction for the areas of unlicensed BRS spectrum (all BRS spectrum outside of the licensed circles). However, unlicensed EBS spectrum has never been made available to the public, and thus remains under FCC control. This unlicensed spectrum is precisely what will be auctioned off in early 2021. 

Given that the EBS Whitespace Auction is focused on the unlicensed area surrounding existing licenses, a basic understanding of how current EBS license areas are structured is necessary to evaluate the available whitespace areas.

Existing EBS licenses are organized into what are referred to as geographic service areas — or GSAs. According to the FCC’s licensing description for BRS and EBS spectrum, “the GSA of a P35 license (which can be either BRS or EBS) generally consists of the station’s 35-mile radius around the protected service area coordinates. In those instances where two co-channel stations have overlapping protected GSAs, the GSA of each license may be reduced due to the ‘splitting the football’ approach used to divide the overlap area between the licensees.” The FCC’s Universal Licensing System (ULS) database does not reflect changes made to the GSAs based on overlapping service areas. 

In developing our EBS Whitespace Auction Opportunities Tool, we have generated geographic license areas for every existing license across all EBS and BRS channels. While there are other companies that may make available their interpretation of each licensee’s GSA, our license areas take into account many of the nuanced licensing details that are easy to overlook. Our licensing expertise ties back to our president’s time spent at Clearwire as their Director of Spectrum Operations, where he developed a profound understanding of EBS/BRS licensing. This experience has contributed to what we believe is the most accurate representation for all of the EBS/BRS license areas. No one has attempted to analyze each county’s whitespace based upon these license areas, making the resulting data, available in our EBS Whitespace Auction Opportunities Tool, a crucial part of your Whitespace Auction strategy which is not available from any other source.

Our license areas account for:

  • Original P35 licenses
  • Overlapping P35 licenses with changes based on football splits
  • Licenses filed after original GSAs were generated
  • Removal of GSAs for canceled licenses

Auction Channels & Sub-Channels

For the EBS Whitespace Auction, the FCC created individual auction channels from the EBS channels illustrated previously. The original sub-channels have been allocated to form the three distinct auction channels.

Each of the auction channels is a different size in terms of bandwidth. Below are the sizes of each auction channel, measured in MHz:

    • Channel 1: 49.5 MHz
    • Channel 2: 50.5 MHz
    • Channel 3: 1 MHz & 16.5 MHz

The EBS Whitespace Auction Opportunities Tool


The EBS Whitespace Auction Opportunities Tool is an Excel-based product which provides insights into the available 2.5GHz unlicensed spectrum for each of the three EBS auction channels. This tool will allow all interested parties — including wireless carriers, telephone companies, internet service providers, and investors — to determine the amount of available spectrum that can be licensed in a county.

The Auction Opportunities Tool is designed to show the number of people that can be served within the whitespace in each auction channel at a county level.

The composite view of all US counties provides insights into the areas where spectrum is available and a larger picture of the overall size of the EBS Whitespace Auction. The primary tools available within the Auction Opportunities Tool are:

    • Population View
    • Population Percentage View
    • Whitespace Area Mapping

Population & Population Percentage Views

What are MHz-POPs?

When looking at the geographic whitespace in a county, there is the potential for each sub-channel’s unlicensed areas to look different. In the EBS Auction Opportunities Tool, we have summarized the amount of people that fall into the whitespace areas for each county. The total MHz-POPs available in each auction channel has been calculated accordingly.

MHz-POPs is a measurement of how much spectrum is available across a market area, typically defined by its population. For EBS spectrum, MHz-POPs are calculated by taking the population available in each sub-channel times the MHz bandwidth of that channel. Since cell phone service is a revenue opportunity tied back to individual consumers, MHz-POPs is a measurement that allows auction participants to forecast the total opportunity within an area of whitespace in a county, therefore determining the general value of the spectrum area.

For example, for two counties in West Virginia, the whitespace area matches the county boundary for the entirety of EBS Auction Channel 1 (figures 7 & 8). This is clearly demonstrated using Population Percentage View (figure 9), which shows that 100% of the total county population falls in the whitespace area for each of the sub-channels that make up EBS Auction Channel 1. To make this more apparent, we employ a “heat chart” format where channels with lower available population% are indicated in red, while high available population% are green. Accordingly, Kanawha and Putnam counties are both highlighted in green across Auction Channel 1. The implication of this data is that the available whitespace population in these counties is equal to the county population and the winning bidder will have access to the entire EBS Auction Channel 1 (49.5 MHz) over the entire county population. 

The exact number of people that channel 1 would be able to reach, if licensed, can be evaluated using Population View, which shows the actual whitespace population for each county, along with the total MHz-POPs available for EBS Auction Channel 1 (figure 10). In Kanawha County, the total population is 193,063 x 49.5MHz (channel 1 width), resulting in 9,556,619 MHz-POPs.

In some counties, the unlicensed area will be different for several of the sub-channels. In Douglas County, Nevada, the amount of available whitespace for Auction Channel 1 ranges from 4% (red) to 93% (green) of the total county population. Accordingly, the winning bidder for Auction Channel 1 in Douglas County could use the 5.5MHz B2 channel to reach 93% of the county population with a wireless signal.

In Population View, the raw population counts in each sub-channel’s whitespace area are shown, along with the total MHz-POPs for the entire auction channel. Looking at the B2 sub-channel in Douglas County, one is able to determine that over 43,000 people could be served with a 5.5MHz wireless signal on this sub-channel.

Whitespace Area Mapping

To accurately represent whitespace areas geographically at a county-by-county level, we have added an EBS Auction section to our Web Spectrum Viewer tool. In this section, you will see a similar population view and population percentage view as the Excel tool. In the web view, the user has the ability to select individual sub-channels by clicking the corresponding cells. This will reveal the whitespace area for that specific sub-channel represented visually. Here, a user can gain important insight to more accurately evaluate the available whitespace in that county. Cities, roads, and other landmarks are clearly identified on our Whitespace Area Mapping tool, making it easy to determine whether or not they fall within the available unlicensed areas.

Additional Mapping Files

In addition to geographic mapping through our Web Spectrum Viewer, we are also providing MapInfo TAB files and Google Earth KMZ files as part of each one-time subscription. This would allow the user to utilize these mapping layers in conjunction with their internal infrastructure data. 

Tribal Land Licenses

Before the EBS Whitespace Auction goes live, first priority for this spectrum has gone to Native American Tribes to access the whitespace spectrum overlapping with their tribal lands. Each tribe is required to submit an official FCC application to acquire this spectrum, and new Tribal Land licenses are being granted periodically. The information regarding individual Tribal Land licenses will be included in our Whitespace Auction Opportunities Tool. However, as this process is still ongoing, these newly licensed tribal areas are not yet removed from the overall whitespace area on our tool. Once all tribal licenses are finalized by the FCC, our geographic files and our Whitespace Population tools will be updated and made available to all Whitespace Tool users.

We will provide the tribal lands overlay (see below) as new applications are finalized by the FCC, so the effect of the tribal licenses can be predicted as things progress.


The EBS Whitespace Opportunities Tool is available for purchase in two different versions: a national version with all fifty states and US territories, or a specific state-by-state version. In the state-by-state version, you will have the ability to specify as many states as you would like. On our website, simply select the State version of this product, then specify the number of states you’d like to purchase in the quantity field provided. On your way to check out, you will be given the option to “add special instructions.” In the corresponding text box, indicate exactly which states you want included in your one-time subscription.


The EBS Whitespace Opportunities Tool is delivered by download from a cloud service. A link for this download will be provided after your payment is confirmed. Typically you will have access to the data within the same business day of your payment being processed.

All purchases are corporate subscriptions, which allow any employee within the same email domain to utilize the data and request access to the Web Spectrum Viewer.

C-Band Auction | Markets and When the Spectrum will be Available Mon, Nov 30, 2020

With Auction 107 officially starting a week from tomorrow, we developed a two helpful graphics to indicate when the C-Band channels will be available in each of the Top 100 Partial Economic Area (PEA) markets.  The A channels indicated in green will be available by December 5, 2021 with all of the yellow channels available by December 5, 2023.  The Honolulu HI PEA will not have C-band spectrum available as the spectrum is reserved to meet the continued satellite video demand.



Which AWS-3 Licenses are at the center of the FCC - Dish Decision? Thu, Nov 19, 2020

Today, the FCC ruled that Dish should not have received small company discounts for their bidding partners in the AWS-3 auction, meaning that Dish would need to pay full price for the spectrum licenses won by Northstar and SNR or they would need to return the spectrum to the FCC for a re-auction.

Below is a map that reflects the AWS-3 spectrum that would be available at auction if Dish declines to pay the full auction price.

The next questions will focus on who could benefit most from this spectrum.  In the image below from our Spectrum Ownership Grid, the AWS-3 ownership for the Top 3 US markets are shown.  The columns filled with "FCC" indicate the spectrum that would be re-auctioned, so there would be a 5x5 channel in the New York EA (Economic Area Market) and a 10x10 channel in the Chicago market between the Chicago CMA (G channel) and the Chicago EA (H channel).  It is work noting that AT&T already has a strong position in these markets, but Verizon lacks AWS-3 spectrum in each of these markets, although no AWS-3 spectrum is available in the Los Angeles market.


Tribal Boundaries - EBS Auction (2.5 GHz) Tue, Nov 03, 2020

On October 23, 2020 the FCC granted EBS whitespace licenses to 154 Tribal  Applicants through the Tribal Priority Window.  This is the first stage to the EBS (2.5 GHz) auction.  Below is a map representing all 154 tribal areas (in brown) along with the licensing contours (in green) for the EBS A1 channel.  Most of the 154 tribal applications claimed the unlicensed (whitespace) area for each of the three EBS auction channels.  


It is important to recall that each of the EBS auction channels consists of multiple existing EBS channels that have different existing licensing boundaries.  EBS Auction Channel 1 consists of the A1 channel shown in the map along with 8 other EBS channels. In the map below, we show how the Tribal whitespace boundaries overlap with the existing license boundaries in Southern Utah and Northern Arizona.  For the areas that are covered by the green licensed areas, the Tribal applicants do not have access to the A1 channel in EBS Auction Channel 1.

To determine the amount of spectrum available to each Tribal area, you must evaluate the available whitespace area with the Tribal boundary for each existing license channel like we did above for the EBS A1 channel.

US Carrier - Individual Spectrum Ownership Charts Thu, Oct 22, 2020

In the November 2020 updates to our Mobile Carrier and Millimeter Wave - Spectrum Ownership Analysis Tools, we have added Carrier - Spectrum Ownership Charts that provide a breakdown of each carriers spectrum assets by band classification (low band, lower mid band, and upper mid band) and by frequency band.  Each of these charts are based upon the total MHz-POPs that a carrier controls in each band classification or frequency band.  Within the each Spectrum Ownership Analysis Tool, eight carriers can be selected from the available 2200 licensees and spectrum holders, to compare each carriers spectrum portfolio side by side.

Carrier Spectrum Divisions (by Band Classification):

Carrier Spectrum Divisions (by Frequency Band):

In both tools we continue to also have charts that detail for the same eight selectable carriers, each carrier's proportional ownership for each frequency band.

The Effect of T-Mobile's 600MHz Leases with Dish Thu, Oct 08, 2020

Last month we presented some initial analysis of T-Mobile's agreement to lease 200 - 600MHz licenses from Dish.  Now that we have released our October 2020 Mobile Carrier - Spectrum Ownership Analysis Tool reflecting all of the September 2020 transactions, we can compare the 600MHz results between the October 2020 and September 2020 versions.


Our October 2020 - Spectrum Ownership Analysis Tool reports that T-Mobile controls 12,593,033,060 MHzPOPs in the 600MHz band, an increase of 982,154,940 MHzPOPs over the number of MHzPOPs that T-Mobile held in September.  

Spectrum Grid:

In the Spectrum Grid sequence below, You can see the effect of two transactions that were both filed in September.  First, Charter's lease of Comcast's A block spectrum is seen in the top image (October 2020) and T-Mobile's lease of Dish's D block spectrum can be seen to increase their New York channel size to 15MHz.  The lower image represents each carrier's spectrum held for September 2020.

Evaluating Potential Markets - EBS Whitespace Auction Primer | 2.5GHz (3 of 3) Tue, Oct 06, 2020

In August, we had blog post that discussed the counties that are on the EBS band plan and the way that the EBS license areas were determined.  In this post we are going to examine how to use our EBS Whitespace Auction Opportunities Tool.

The EBS Whitespace Auction Opportunities Tool provides carriers, telephone companies, internet service providers (ISP), cable companies, investors, and financial analysts with the tools to evaluate the opportunities in this auction.

As we discussed before, this auction will provide the winner's access to 3 wide band channels in the EBS (2.5GHz) band.  One channels is 49.5 MHz, one channel is 50.5 MHz, and one channel is a combined 17.5 MHz.  In the images below, we indicate how each of the existing EBS channels (A1,A2,..) are component channels in the larger wide band EBS Auction channels.

EBS Auction Channel 1:

EBS Auction Channel 2:

EBS Auction Channel 3:

The population that a bidder can serve is determined by the unlicensed population for each of the component channels within each EBS auction channel.

Below is an example of two counties in West Virginia where 100% of the county population is available for each component channel in the EBS Auction Channel 1.  In our EBS Whitespace Auction Opportunities Tool this is seen in the Spectrum Grid (% POPs) worksheet.  The percentage of the available unlicensed population is divided by the full county population.

Population Percentage Worksheet:

The second worksheet in the EBS Whitespace Auction Opportunities Tool provides the discrete available unlicensed population for each component channel as well as total MHz-POPs for the entire EBS Auction Channel. 

Population Worksheet:

Our next example is a Nevada county that has varying available whitespace population for each component channel.  In the POPs view immediately below, the available whitespace population for EBS Auction Channel 1 varies from 2,024 for the A1 component channel to 43,872 for the B2 channel.

Population Worksheet:

In the % POPS view, the population comparison to the total county population is highlighted with Red to Green cell colors.  For the A1 component channel, the 2,024 available whitespace POPs represents 4% of the Douglas county population while for the B2 component channel, the 43,872 available whitespace POPs represents 93% of the Douglas county population.

Population Percentage Worksheet:

Available Whitespace Area:

In addition to Population Analysis to each component channel, purchasers of the EBS Whitespace Auction Opportunity Tool also receive access to our EBS Whitespace Mapping module in our Web Spectrum Viewer.  Selecting either the A1 component channel cell for POPS or for % POPs, the whitespace license area map for that component channel is displayed.

A1 Component Channel Whitespace Area:

For the B2 component channel the whitespace license area fills a majority of Douglas county reflecting the 92% population availability.

B2 Component Channel Whitespace Area:

The EBS Whitespace Auction Opportunities Tools is available either as a nationwide purchase (all 50 states and US territories) or a state by state purchase.  The purchase will enable carriers and investors to evaluate their opportunity to add 2.5GHz spectrum in the targeted markets and it will allow investors to quantity the national or state opportunities for these new channels as well as provide an evaluation of the strength or weakness of the existing 2.5GHz licensee in each market.



T-Mobile's 600MHz Spectrum Leases - More work still needs to be done Tue, Sep 22, 2020

Last week, T-Mobile filed to lease 200 of Dish's 600MHz licenses after receiving Department of Justice (DOJ) approval for the leasing terms.  We are going to examine how these new leases will impact T-Mobile 600MHz network and identify the markets where work will need to continue on T-Mobile's part to consolidate their available 600MHz spectrum into a contiguous block for LTE, 5G, or both.  To start this analysis, we are going to look at the new T-Mobile leases for spectrum in the Top 20 Partial Economic Area Markets.
New York:
In the New York market, T-Mobile will add the D block to their spectrum portfolio.  In the image below from our Web Spectrum Viewer, you can see the D block still in Dish's control with our Future Holdings dataset.  As a reminder, our tools enable users to select to see either Licensed Holdings, Current Holdings, or Future Holdings in the Spectrum Ownership Grid.  Licensed Holdings reflects the carrier that directly owns that spectrum license, Current Holdings reflects either the current license owner or the long term lessee if the spectrum license is leased.  Future Holdings reflects the current operator of the license unless there is a pending assignment (acquisition) or a pending lease filed with the FCC for that particular license.  Since these T-Mobile leases were just filed, they will be rolled into our end of month update so after October 5th, the D block in this Future Holdings view will reflect TMO instead of DSH, but the Current Holdings will reflect DSH until the lease is finalized.  Now back to the effects on T-Mobile's network: Dish's D block will allow T-Mobile to increase their LTE/NR channel size from 10 MHz to 15 MHz in all 28 counties included in the New York PEA market.
It is also interesting to note that Comcast's A block in New York, is being leased by Charter.  This new lease application was also filed last week.  You can get access to these weekly spectrum transactions by subscribing to our Weekly Spectrum Transaction Summary.
In Miami, the effect of T-Mobile leasing the F block is straightforward,  It will increase T-Mobile's LTE/NR channel size from 15 MHz to 20 MHz.
In Detroit, T-Mobile already controls 15 MHz of spectrum but the F block they are leasing from Dish is separated by the D block that Comcast (XFI) owns.  If T-Mobile actually owned the spectrum it would be relatively easy for Comcast and T-Mobile to exchange the F block for the E block, but with Dish owning the license, that exchange would have to be initiated between Dish and Comcast.
In Orlando, T-Mobile faces a similar challenge preventing them from utilizing the entire 15 MHz that they will control in the market.  This would need to be another trade between Dish and Comcast.
In Cleveland, Dish's F block is again separated from T-Mobile's core 15 MHz holdings by a 5 MHz channel owned by Grain Management.  In this market T-Mobile will need Dish and Grain to agree to swap spectrum licenses so they can fully utilize the 20 MHz of spectrum they will have in this market.
San Diego:
In San Diego, T-Mobile will immediately be able to expand their 15 MHz LTE/NR channel to 20 MHz with Dish's F block channel.
In Portland T-Mobile has another opportunity for Dish and Comcast to trade spectrum licenses.  The most logical exchange may actually be for Dish to trade their G block channel for Comcast's E block, so they still control 10 MHz of contiguous spectrum if they cancel T-Mobile's lease.  If this exchange took place T-Mobile could increase its channel size from 10 MHz to 15 MHz.

Where is there excess GAA Spectrum? Mon, Sep 14, 2020

With the completion of the CBRS auction, there were 2006 PAL licenses that were not purchased.  In a typical auction, the unpurchased licenses continue to be held by the FCC until they schedule another auction.  With the CBRS spectrum, these licenses become part of the General Authorized Access (GAA) pool in each county.  We have updated our  Mobile Carrier - Spectrum Ownership Analysis Tool, to reflect the auction results and we also show the total spectrum available for GAA in each county.  In our Spectrum Grid modules you can see that the GAA spectrum in Putnam County, NY includes all but 20 MHz of the 150 MHz available.  
From a national level, the counties that have more than the minimum amount of GAA spectrum (80 MHz) are shown in the map below.

Frequency Band Ownership - CBRS PAL Licenses Tue, Sep 08, 2020

The 10 highest bidders in the CBRS auction are shown in the table below.  How did each of these bidders' investments translate into the percent of the their ownership within the CBRS band? 


In our Frequency Band Ownership chart from our updated Mobile Carrier - Spectrum Ownership Analysis Tool, you can see the relative ownership percentages based upon each bidders total MHz-POPs in the CBRS band.  Clearly the top 5 bidders turned their investment into a significant share of the CBRS band.

Geographic Service Areas - EBS Whitespace Auction Primer (2 of 3) Tue, Aug 11, 2020

The primary challenge in evaluating the EBS Whitespace auction opportunities, lies with the available licensing information provided by FCC.  For each of the EBS licenses, the FCC provides a map for a 35 mile radius circle from the license centerpoint.  Below is the FCC map for WHR463, an EBS A1 channel license in Los Angeles county.  Not indicated in this map, is the overlap that this license has with two other A1 channel licenses in Los Angeles county.


In two images below, it is clear that a significant portion WHR463's 35 mile radius license area is shared with WHG227 and WND634.  



The FCC resolves these overlap issues through the creation of Geographic Service Areas (GSA) for each license_channel combination.  The starting point is to look at all of the 35 mile overlaps on an individual channel basis, e.g. A1, A2, ...

Here is an example case with 5 licenses in a 4 county area.


The Geographic Service Areas are initially created by bisecting each of the overlapping areas (splitting the football) so each license has its own exclusive area.


 The GSA's were formed based upon active licenses on a specific date.  Licenses that were issued after this date (PSA6) do not claim any part of the overlap area with existing GSAs.

 These GSA's are sometimes referred to as "Cookie Bite" GSAs.


After the GSA's were formed, any cancelled or terminated licenses lost their area, but none of that area is added to the GSAs that previously overlapped the cancelled/terminated licenses.



The map below represents the licensed spectrum in this 4 county area, prior to the EBS Whitespace Auction for a specific channel.

The final representation of the unlicensed (whitespace) area in each county that will be available in the auction is the area from the GSA boundary for each license to the county boundary.


Going back to Los Angeles County A1 channel example, you can see the WHG227, WHR463, and WND634 licenses in the center of the map reflecting each of their A1 Channel GSAs.

Our final map indicates the whitespace area for the A1 channel in Los Angeles county.  Call signs WHG227 and WND634 were both cancelled after the GSA boundaries were computed, thus their license area is now part of the A1 channel EBS Whitespace, indicated in the orange cross hatch. 




Counties on the Wrong Band Plan - EBS Whitespace Auction Primer (1 of 3) Thu, Aug 06, 2020

As the Native American Tribal Window for acquiring unlicensed 2.5GHz spectrum winds down, we felt it would be a good time to begin an education process for the EBS Whitespace Auction through a series of blog posts.  Our first post is focusing on the markets (counties) where the existing licensees are operating a band plan that is incompatible with the established 3 channel auction configuration.  The counties below in red still have EBS licenses that are operating video broadcast systems which utilize what is referred to as the pre-transition band plan.  We posted a blog in 2018 that discussed the transition from the pre-transition band to the post transition band.  This transition was necessary to provide Clearwire, and then Sprint with spectrum free from video interference on which they could deploy LTE.
FCC Pre-transition Band Plan:
As a quick review, the pre-transition band plan interleaved different licenses, e.g. A channels and B channels.  A licensee would typically control all of the A channels (A1, A2, A3, and A4) or the B channels (B1, B2, B3, and B4).
Source: FCC
If the channels haven't been transitioned, you won't have the same individual channel sizes (the video channels were all 6 MHz, while now the A1, A2, and A3 channels are 5.5 MHz), and they can't be grouped to make the same Auction Channels like the 49.5 MHz Channel 1 below.
EBS Auction - Channel 1:
The EBS Auction - Channel 2 is the first place we begin to see the guardband channels that were created in the transition process.  Each of these channels is 0.33 MHz.  For the pre-auction licenses, the owners of the guardband channel JA1) is the owner of the A1 channel in the same geographic area.  Channel 2 below is the 50.5 MHz EBS Auction channel.
EBS Auction - Channel 2:
The final EBS Auction - Channel is the only one that has two discontiguous blocks of spectrum.  It has 1 MHz of spectrum in the KG guardband channels and 16.5 MHz of spectrum in the G channels.
EBS Auction - Channel 3:

Sub-6 GHz Spectrum Screen and the Effects on the CBRS and C-band Auctions Tue, Jul 07, 2020

Recently the FCC has revised the Sub-6 GHz spectrum screen through the following rulemakings;  the CBRS report and order, the 2.5GHz spectrum transformation report and order, and the C-band report and order.*  In the chart below we reflect the spectrum allotments that are included in our Mobile Carrier - Spectrum Ownership Analysis Tool compared to the allotments that apply to the FCC Spectrum Screen.

The FCC divides the Spectrum Screen Total by 3 and rounds to 10 MHz.  So the Spectrum Screen seems to be set at 340 MHz for Sub-6 GHz spectrum.

Beginning with our July 2020 release of the Mobile Carrier - Spectrum Ownership Analysis Tool, we have updated our Spectrum Screen calculations to include the additional EBS and C-band spectrum.  

The Spectrum Screen calculations are available in the County Analysis Module, the CMA Market Analysis Module, and the PEA Market Analysis Module.

In the County Analysis Module, the Spectrum Screen values are displayed for each of 8 selected carriers for each US county. Nearly 2,000 carriers and spectrum owners can be selected for analysis.  Auto filters can be set on the 340 MHz spectrum screen value, or set lower to forecast the head room a carrier would need to acquire 100 MHz of spectrum in the C-band auction without exceeding the spectrum screen.

The analysis carries over to the PEA Market Analysis Module and the CMA Market Analysis Module where auto filters again can be set to model specific conditions to determine carriers likely thresholds by market.

USA National Carriers TOTAL Spectrum Tue, Jun 02, 2020

Why don't we see charts that show both Sub 6GHz and Millimeter Wave Spectrum?  I created the chart below to illustrate each carriers low band, mid band, and millimeter wave (high band) spectrum ownership.  This is not a view that I favor because the spectrum that is the most important today and likely for at least the next 5 years in buried at the bottom of the chart.  The values in the chart represent the population weighted average of each carrier's spectrum.  The important features of spectrum for the next 5 years will center on upper mid-band spectrum where 5G networks can have significant speed/capacity along with reasonable coverage.   Upper mid-band spectrum will be the only spectrum where large channel sizes (greater than 20MHz) will be available, but it is clearly difficult to evaluate each carriers available spectrum when the bar graphs are dominated by millimeter wave spectrum.


Commericializing Educational Broadcast Spectrum - 2.5GHz Tue, May 26, 2020

Last week we saw the first applications filed at the FCC that transfer educational (2.5GHz) spectrum to commercial carriers.  These are the first applications received by the FCC that take advantage of the new rules that were released in the Transforming the 2.5GHz Band Report & Order.  Below are the details for the  Educational Spectrum transfers from our Spectrum Transaction Summary that was released last Friday.  Prior to this Report & Order, commercial carriers could only utilize the educational spectrum via a spectrum lease.

5G Reconfiguration in Mexico Tue, May 19, 2020

In April, El Economista highlighted a transfer of 3.5GHz spectrum in Mexico from Telmex to Telcel.  The article highlights a series of consultations between Telmex, Telcel, AT&T, and the Federal Telecommunications Institute (IFT).  I will use our Mobile Carrier - Spectrum Ownership Analysis Tool (MEX) to examine these transactions and the overall 5G spectrum plans in Mexico.

Our Spectrum Grid from December 2019, reflects the ownership of the 3.5GHz band prior to the Telcel acquisition.  At this point, Telmex, AT&T, and Axtel each owned 50MHz of spectrum (25MHz of uplink and 25MHz of downlink spectrum).  In this view we included a TDD band class 48 which is the only band class defined by 3GPP for this band.  Obviously, systems using this band configuration are not using band class 48 since they are FDD and band class 48 is TDD.

AT&T and Telmex approached the Federal Telecommunications Institute (IFT) in December to request that they exchange AT&T's D channel for Telmex's H channel, providing each carrier with 50MHz blocks of spectrum in the 3.5GHz band.  This exchange only makes sense if IFT reconfigured the entire band to TDD spectrum. 

The new configuration is reflected in the image below with Telcel acquiring Telmex's 50MHz channel.  Now Telcel and AT&T are set up with the minimum 5G channel size in one of Mexico's two TDD bands and IFT also has 150MHz of spectrum remaining for a future auction.  It is interesting to note, that both Canada and Mexico have opted for licensing spectrum directly to carriers for their 3.5GHz bands while the USA has gone with the shared spectrum and PAL licensing approach.



TeraGo Networks | FDD then TDD: Canada's Millimeter Wave Spectrum Dilemma Tue, May 12, 2020

Last week, Lightreading published an article about TeraGo's Fixed Wireless aspirations utilizing 24GHz and 38GHz.  We have just updated our Millimeter Wave - Spectrum Ownership Analysis Tool (CAN) to reflect the recent (ISED) consultation outlining Canada's millimeter wave spectrum configuration and upcoming auction.  This is important because TeraGo's plans rely on the existing paired spectrum configuration of the 38GHz band plan.  This band plan was compatible with the US 39GHz plan prior to Auction 103 when the plan was changed to TDD channels. 


Canada is changing the configuration of the above 38GHz band from fixed use to flexible use along with adding the spectrum down to 37.6GHz and up to 40GHz.  This creates a 37/39GHz band that is compatible with the US spectrum plans.  



Now that ISED has chosen to reconfigure the 38GHz they needed to either cancel the existing licenses from the 38GHz Fixed Service or create a transition plan.  ISED opted for the transition plan.  The existing 38GHz licenses will transition to an equal amount of spectrum in the 37/39GHz band at the end of their existing 10 year license term.  Looking at several of TeraGo's licenses, it appears that transition will occur in 2025.
