The 30 dB limit is for devices in master mode, for clients the limit seems to be 250 mW (about 24 dB). Given the TPC requirement for U-NII devices the most it could be bumped up to is 21 dB, unless there's some other reason I don't know about to keep it at 17 dB. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
