(Telecompaper) The FCC has proposed opening up spectrum above 24 GHz for mobile services. While it was previously assumed physical and technical limitations could not support mobile service in these bands, the FCC noted that new tech developments may allow the use of these high frequencies for mobile applications like 5G service, offering significantly more capacity and faster speeds for next-generation mobile services. On the path to 5G, the US regulator said it will create new flexible use service rules in the 28 GHz, 37 GHz, 39 GHz and 64-71 GHz bands. If approved by the full commission, these bands would be available using a variety of authorization schemes, including traditional wide area licensing, unlicensed and a shared approach that provides access for both local area and wide area networks. The FCC also outlined a path for a variety of platforms and uses, including satellite uses, to coexist and expand in this spectrum, through market-based mechanisms. The regulator called for "extensive comment" from the market on the service, licensing and technical rules for facilitating flexible use in these bands, as well as other frequencies over 24 GHz with potential use.
