 The transmitted center frequency tolerance shall be ±20 ppm maximum.
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 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.
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 the rest of the sub-carriers.
