Transmit
spectrum
flatness
For 802.11g the average energy of the constellations in each of spectral lines

16..-1 and +1..+16 will
deviate no more than +/- 2dB from their average energy.

Carrier
suppression
802.11a:
The leakage of the center frequency component shall not exceed -15 dB relative to overall
transmitted power or, equivalently, +2 dB relative to the average energy of the rest of the sub-
carriers.
802.11b:
The RF carrier suppression, measured at the channel center frequency, shall be at least 15 dB below
the peak SIN(x)/x power spectrum.
802.11g:
The leakage of the center frequency component shall not exceed -15 dB relative to overall
transmitted power or, equivalently, +2 dB relative to the average energy of the rest of the sub-
carriers.
802.11n:
For all 20 MHz modes of transmission, the leakage of center frequency component shall not exceed -
15 dB relative to overall transmitted power or, equivalently, +2 dB relative to the average energy of
rest of sub-carriers.
For all 40 MHz modes of transmission, the center frequency leakage shall not exceed -18 dB relative
to overall transmitted power, or, equivalently, +2 dB relative to the average energy of rest of sub-
carriers.
