We consider Linux devices to be client or user terminal devices, so this
needs to be reduced to 24 dBm. However, this is further limited by the
spectral density clause, which states a limit of -1 dBm / MHz. Given
the smallest channel is 20 MHz, this gives a new limit of 12 dBm.

This is basically the same as the one for the US.


Thanks
ChenYu
