Sec. 15.403  Definitions.

    (a) U-NII devices (Unlicensed). Intentional radiators operating in 
the frequency bands 5.15--5.35 GHz and 5.725--5.825 GHz that provide a 
wide array of wideband, high data rate, digital, mobile and fixed 
communications for individuals, businesses, and institutions.
    (b) Peak transmit power. The peak power output as measured over an 
interval of time equal to the frame rate or transmission burst of the 
device under all conditions of modulation. Usually this parameter is 
measured as a conducted emission by direct connection of a calibrated 
test instrument to the equipment under test. If the device cannot be 
connected directly, alternative techniques acceptable to the Commission 
may be used.
