You mention that some conditions are required for outdoor use of this
range. One of those is TPC, which would require reducing the max EIRP to
50 mW. There's also some language about the SSID format which implies a
license might be required, but it's not entirely clear from the
translation I'm reading. Seems like it might be best to keep this at 100
mW, NO-OUTDOOR.

These changes all look fine to me.

Thanks,
