The FCC revised technical specifications in the 4.9 GHz band to allow manufacturers to adapt, for that band, technologies that are being used in adjacent spectrum bands, such as the 5.4 GHz Unlicensed National Information Infrastructure (U-NII) unlicensed band and the Intelligent Transportation System (ITS) band. Specifically, the FCC adopted two emission masks limiting interference potential for the band, one for low-power and one for high-power operations. These changes will allow public safety licensees to leverage commercial off-the-shelf technologies available for the U-NII and ITS frequency bands. http://www.fcc.gov
