 ### What is a Broadband Service Location (BSL)? {#sec-BSL}
 
 > A broadband serviceable location is defined as “a business or residential location in the United States at which fixed broadband Internet access service is, or can be, installed.”  A residential BSL includes all residential structures, including structures that are (or contain) housing units or group quarters (as those terms are defined by the United States Census Bureau).  A business BSL includes “all non-residential (business, government, non-profit, etc.) structures that are on property without residential locations and that would expect to demand Internet access service.” (source FCC[^fcc_bsl])

+NBM has two big releases per year (June and December) and have "unofficial" versions every two weeks to take into account challenges[^challenges]. Experience has told us that sometimes their release can be faster (more than one per week) or slower. The FCC did not (April 2024) provides a changelog between releases or versions (but the documentation has some of the major changes[^nbm_chnagelog] ).

+## What is unserved? Underseved?
 
-## What is unserved? Underseved? (BSL / block area) 
+Unserved, Served and Underseved are **overlapping* categories at the location level. They can be extended at the "area level".
+
+A location is said **served** if it has a services that have equal or above 25 Mbps downstream speed and 3 in upstream (25/3 to simplify). If a location has internet below those numbers it is **unserved**. 
+
+Underserved is sub category of "served": if a location has a service with speed that are between 25/3 and 100/20 it is said to be **underserved**.
+
+Those definition are specified in (TODO ref) and can be changed by States[^pew_list].  
+
+:::.{aside}
+FCC could change that for 100/20: [https://www.fcc.gov/document/fcc-increases-broadband-speed-benchmark](https://www.fcc.gov/document/fcc-increases-broadband-speed-benchmark)
