Carrier
suppression

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 the center frequency component shall not exceed -15 dB relative to
overall transmitted power or, equivalently, +2 dB relative to the average energy of

transmitted
power, or, equivalently, +2 dB relative to the average energy of the rest of the
sub-carriers.
