Last week, FirstNet released two public notices (available here and here) that include more than 60 key legal interpretations and definitions.  One definition finalized by FirstNet last week is the term “rural.”  The definition adopted by the agency mirrors the definition under the Rural Electrification Act of 1936, which defines the term “rural” as any area that is not a city, town, or incorporated area with a population of greater than 20,000 inhabitants, or any urbanized area contiguous and adjacent to a city or town with a population of more than 50,000 inhabitants.  FirstNet also confirmed it will require fee revenues from states assuming responsibility for building their own radio access networks (RANs) to be reinvested into the nationwide system.
