(1)
Transmit power will be reduced by 1.5dB for V

(2)
The 11g/n low rates on edge channels (2412 and 2462 MHz) have reduced TX power to meet FCC emission limits.
(3)
Power of 802.11b rates are reduced to meet ETSI requirements in Europe.
(4)
Channels 1 (2142 MHz) through 11 (2462 MHz) are supported for FCC.
(5)
Channels 1 (2142 MHz) through 13 (2472MHz) are supported for Europe and Japan. Note that channel 14 is not supported for Japan.

FCC channels 36, 60, 64, 100, and 140, where harmonics/sub-harmonics of fall in the FCC restricted band, have reduced output
power to meet the FCC RSE requirement.
(3)
The edge channels (100 and 140) have reduced TX power to meet FCC emissions limits.
(4)
FCC band covers U-NII-1, U-NII-2A, U-NII-2C, and U-NII-3 20-MHz BW modulations.
(5)
Europe bands 1, 2 and 3, 20-MHz BW modulations are supported.
(6)
For Japan, W52, W53 and W56, 20-MHz BW modulations are supported.
