Fabric & BDC Data

BDC Service Availability Comparison Dashboard

*Note: How to read the BDC Data Dashboard

Filters – Left-hand pane

• Filter by state – use the State drop-down to filter based on State or States you are interested in. 
• Filter by county – Filtering by county is easier once you have selected a state filter. After selecting the state, the county filter is narrowed to only the counties in that state(s). 
• To clear these filters, hover in the upper right corner of the drop-down area until an eraser appears, and then click the eraser – this returns you to results for the full nation. 
• BDC Tables  
  • Choose which versions of the BDC you are interested in comparing. 

All BSLs Tab

• KPIs – The three KPIs at the top indicate the percent difference by coverage status between the Old and New version of the BDC.
  • A positive change in served from old to new is good. This means that more BSLs are now being identified as served by a provider.
  • A negative change in unserved from old to new is also good. This means that BSLS that were previously considered unserved have now become either underserved or served.
  • Changes in underserved are less straightforward. Look to the changes in served and unserved to determine where the changes are coming from.

• Sankey Diagram: BSL Coverage 
  • The bars on the left side represent the coverage statuses in the older version of the BDC that is being compared. 
    • New: this status means these BSLs were not in the old version of the Fabric (thus could not be submitted to the BDC). They are present in the new version.  
  • The bars on the right side indicate the coverage statuses in the new version of the BDC. 
    • Dropped: this status indicates that these BSLS dropped out of the fabric from the old to the new version and therefore could no longer be submitted in the BDC.
  • The lines that connect the old version’s coverage bars to the new version’s coverage bar represent BSL counts.  
    • The thicker the line the more BSLs. 
    • These lines show how the BSLs either changed coverage status or remained the same. 
    • If you follow the lines from the New grouping, you can see how many of the new BSLs were submitted to the BDC as served, unserved or underserved. 
    • If you hover over the line, it will show you the BSL count. 
    • If you hover of the coverage bar you can see the total count.  

• Coverage by Version bar chart 
  • Bar chart which shows the count of BSLs by coverage status by version.  
    • Essentially this, is showing the coverage bars from the Sankey diagram side by side.  
  • The new and dropped columns are double counted in this chart. The counts from these bars are also included in the normal coverage bars (s/un/und), but they are shown to give a visual. representation of how much they represent from the whole. 

Coverage Change Tab

• The only difference on this tab from the All BSLS Tab is the Sankey diagram. 
• This diagram has been filtered to show only the BLSs that changed coverage status. If the BSL did not change from served to unserved or underserved to served, etc, then it is now excluded from this chart. 

Sankey Table View Tab

• This table is the Sankey Diagram from the first tab in a table view 
• Fields 
  • State 
  • County Name 
  • New Coverage – This is the coverage status in the new version. 
  • Old Coverage: Served – This represents the BSL count that was considered served in the old version but now has the new version’s coverage (field above). For example, if the New coverage = Served and Old Coverage: Served =234 this means that there are 234 BSLs that are considered served in the new version and they were also considered served in the old version.  
  • Old Coverage: Underserved – This represents the BSL count that was considered underserved in the old version but now has the new version’s coverage. For example, if the New coverage= Served and Old Coverage: Underserved =15 this means that there are 15 BSLs that are considered served in the new version, but they were considered unserved in the old version.  
  • Old Coverage: Unserved – This represents the BSL count that was considered unserved in the old version but now has the new version’s coverage. For example, if the New coverage= Served and Old Coverage: Unserved =3 this means that there are 3 BSLs that are considered served in the new version, but they were considered unserved in the old version.
  • New BSLs – This shows the number of new BSLs. So if the New Coverage Field = Served and New BSLs= 125. That means these 125 BSLS were not in the old version, but they are in the new version and were submitted to the BSL as Served.
  • Total Column – represents the total number of BSLs that have been submitted to the BDC with the New Coverage Status.  

Coverage definitions used in analysis

Served – access to a low-latency Fiber, Cable, Copper, or Licensed Terrestrial Fixed Wireless offering of speeds greater than or equal to 100 Megabits per second (Mbps) download and 20 Mbps upload, or 100/20 Mbps (download/upload).

Underserved – access to a low-latency Fiber, Cable, Copper, or Licensed Terrestrial Fixed Wireless offering of speeds less than 100 Megabits per second (Mbps) download and 20 Mbps upload, or 100/20 Mbps (download/upload) but greater than or equal to 25 Megabits per second (Mbps) download and 3 Mbps upload. 

Unserved – without any Terrestrial Broadband Service or with internet service offering speeds below 25/3 Mbps (download/upload) or latency greater than 100 milliseconds.

*For this analysis and data dashboard we don’t include unlicensed fixed wireless or satellite technologies when determining coverage status – following NTIA BEAD requirements.
