Countries around the world have been adopting different regulations regarding the 5 GHz spectrum, with some only considering certain frequency ranges. Surprisingly, the United States has adopted three separate Report and Orders for the 5-7 GHz spectrum, while others like Argentina and Brazil have adopted a wider range.
