I've looked through the 6 GHz statement. One thing I'm not clear on is whether the decision is effective immediately or only once the relevant regulatory documents have been ammended (as noted in section 6.3). I did not find an updated IR 2030 at least, so I wonder if these changes should wait for that. > So in summary, the change you just made (sorry) can now be set to *NOT* need DFS in the high > channels around 5.7Ghz. More details in the links below. The document only seems to state that the DFS requirement is removed for indoor use up to 200 mW EIRP. So this range may also need to have NO-OUTDOOR added if DFS is removed. Hopefully when IR 2030 is updated the restrictions will be clear. > In particular one of the additional frequency ranges (6Ghz) has an intended use of indoor where it > has large power outputs (and encouraged to use larger powers by request of Intel), but it is *ALSO* > allowed to be used outdoor with very low power requirements (possibly it will later fall under the > UK's allowance to use higher output power if you buy a £50 licence?).

The regdb can contain two entries for the same range in a given country, I'm not sure how that will be handled by the kernel though. I'll have to look at the code. > These changes significantly expand the available 5Ghz space in the UK, so would be nice to get > upstream for general use > > > Notes: > > https://www.ofcom.org.uk/__data/assets/pdf_file/0036/198927/6ghz-statement.pdf > > https://www.ofcom.org.uk/__data/assets/pdf_file/0028/84970/ir-2030.pdf > > Thanks if you might make this second change! > > Ed W > > > On 06/11/2020 21:44, Seth Forshee wrote: > > Sorry for not responding sooner.
