Spectrum allocation is an inherently-political process, as it is zero sum game, with winners and losers. So it is that decisions about how to use the 75 MHz of spectrum at the top of the U-NII-4 band (from 5850 to 5925 MHz), now allocated on a primary basis for Intelligent Transportation Systems (ITS), also has supporters of Wi-Fi access in that frequency contesting the primacy of vehicle communications.
The Federal Communications Commission is considering allowing shared use of some portion of the UNII-4 band for Wi-Fi.
The larger issue, New America Foundation suggests, is the use of spectrum sharing, rather than creation of another silo of spectrum, to promote more efficient use of the spectrum.
The issue is how much sharing, over what portions of the spectrum, should be allowed.
