The Federal Communications Commission is drawing up rules for extremely high frequency spectrums that could be used in "5G" mobile broadband.
4G (fourth generation cellular technology) LTE in the US relies on frequencies from 700MHz to 2.5GHz, with the lower frequencies being best suited for covering long distances and penetrating building walls. The FCC's vote today proposes new "flexible use service rules in the 28GHz, 37GHz, 39GHz, and 64-71GHz bands," and seeks public comment on other bands above 24GHz that could also be used.
The FCC has said these frequencies could enable speeds between 1Gbps and 10Gbps. But it will take a lot of work to overcome distance limitations and physical obstacles that can block the signals.
