The FCC announced Friday that it's focusing on using satellite services to spread mobile wireless access to more Americans.
In March, the FCC unveiled a national broadband plan that set a five-year goal of making 300MHz of spectrum available for wireless broadband use. To meet the goal, the agency wants to free up spectrum from five kinds of bands. Bear with the acronyms here: WCS, AWS 2/3, D-Block, broadcast TV, and mobile satellite services (MSS).
