The only difference in limits is in 5250-5350 MHz where HK regulations further restrict it to 200 mW (23 dBm). Since explicit power limits are given I think we should be able to use those. The reference to the US rules probably refers to other requirements. So for 3 we can use 27 dBm and for 4 we can use 36 dBm. > > One last suggestion: I noticed 6 GHz band is allowed for outdoor use at a max of 14 dBm (Section 3.2 of [4]) though it's only for licensed devices.
