Comment (by mrenzmann):

 Please check the explanations given in #194 and
 [wiki:UserDocs/Ubiquiti#PowersettingforUbiquitiSR2], regarding how
 Ubiquiti implements the higher TX power. The same tricks might be used by
 Senao.

 In addition, ETSI has some rules regarding the spectral power, which
 requires devices working with one of the OFDM modulations (used for 54, 48
 and 36 MBit IIRC) to limit TX power to 19dBm instead of 20.

 I wonder what a patch would look like that removes "the software
 limitations from source code" as mentioned by anonymous at 06/15/06
 00:27:35... the TX power limitation is implemented in the HAL, not in the
 driver source, and the HAL also takes care to prevent "clever hackers" to
 use TX power values that are not within what the HAL believes to be
 allowed in the configured regulation domain.
