The U.S. Federal Communications Commission has packaged a number of initiatives to support 5G deployment as the “Facilitate America’s Superiority in 5G Technology” (5G FAST) plan.
Among more significant moves are the release of huge amounts of new spectrum for commercial use, including 5 GHz of spectrum in the 24 GHz, 28 GHz, 37 GHz, 39 GHz, and 47 GHz bands.
Consider that all spectrum now available for mobile use totals less than a gigaHertz. The FCC also is working on releasing another 2.75 gigahertz of 5G spectrum in the 26 GHz and 42 GHz bands.
In the lower millimeter range, the FCC is working to commercialize about 844 MHz of spectrum in the 2.5 GHz, 3.5 GHz, and 3.7 GHz to 4.2 GHz bands.
The FCC also is moving to release as much as 7 GHz of new unlicensed spectrum in the 6 GHz range, as well as capacity above 95 GHz band.
In the 5G era, as millimeter wave spectrum is released, raw bandwidth will increase by up to 1.5 orders of magnitude in physical terms, in many markets. Unlicensed bandwidth alone might grow by about five times to 12 times, compared to available mobile spectrum.
And that will have huge price and capability implications. For the first time, mobile substitution, on a basis comparable with fixed networks, should be possible Access to all that new bandwidth will mean the mobile network’s cost per bit and retail cost, plus usage allowances, should be equivalent to, or perhaps better than, fixed network alternatives.
