Hi, In the latest released regulatory database (http://kernel.org/pub/software/network/wireless-regdb/wireless-regdb-2015.04.06.tar.xz), the transmit power of GB is 20dBm, even for the lower 5GHz channels (e.g. channel 36). country GB: (2402.000 - 2482.000 @ 40.000), (N/A, 20.00) (5170.000 - 5250.000 @ 80.000), (N/A, 20.00) (5250.000 - 5330.000 @ 80.000), (N/A, 20.00), DFS (5490.000 - 5710.000 @ 160.000), (N/A, 27.00), DFS (57000.000 - 66000.000 @ 2160.000), (N/A, 40.00) >From my understanding, and from what I see in: http://www.digitalairwireless.com/wireless-blog/recent/quick-guide-to-5ghz-uk-part-1.html The transmit power should be 23. Is this a bug in the database, or was this restricted intentionally? Thanks, Arnon Meydav
