The FCC is now proposing to open up 500MHz more of spectrum for 5G use, hard on the heels of a date being set for high-band spectrum auction -- likely to be used by the next-gen technology -- for November this year.  

The FCC is proposing opening up spectrum between between 3.7 and 4.2 GHz for broadband mobile usage in the US. "Mid-band spectrum is well-suited for next-generation wireless services," the agency says in a statement, while stressing that the spectrum will be made available for flexible usage.
