Power tables for UK incorrect for 5725-5850

Fri Oct 06, 2023 12:59 pm

Is it possible to get the regulatory information for the UK updated? Currently it shows:
> /int/wifi/radio/reg-info country="United Kingdom" number=0
  ranges: 2402-2482/20
          5170-5250/23/indoor
          5250-5330/23/indoor/dfs
          5490-5730/30/dfs
          5735-5875/14
According to https://www.ofcom.org.uk/__data/assets/ ... -RLANs.pdf, on 5725-5850 200mW is allowed for indoor use (no need for DFS/TPC, license-free), or 4W for outdoor use (with DFS/TPC, license required).

I guess, drivers aren't following this info table, or this table shows only one variant of multiple options, when the power limit depends on more conditions.

The actual tx-power (plus antenna gain, and chains) doesn't seem to behave according to this table. But, it instead behaves according to the real regulatory limits.

Also, this table prints different info for hAP ax³, hAP ax² and hAP ac³ for the same (my) country, on the same RouterOS version.

And just to show the 25mw on the hAP ax2, should be 200MW as OP said.

Here is the latest IR2030 page 42

Did you officially open support ticket? This forum is mostly user-to-user communication channel, MT staffers occasionally come around but no action based on forum discussions is guaranteed.

In this case, discussion on the forum is a good idea too, as MikroTik are not from the UK and we don't know the local regulations so well.
Regarding the above, there might be some overlap in the Ofcom rules themselves, as pointed out by one of our best wireless trainers. Will quote him, hope he doesn't mind:
There are two UK regulations for 5GHz. One for low power devices that do not require a registered paid license (usually WiFi). That’s Interface Requirement 2030 referred to in the posts. It’s the UK Government’s official document. In the top 5.8GHz part there is some overlap of regulations. Ofcom allowed low power use of WiFi into the higher power allowed FWA (Fixed Wireless Access) sub band by extending the IR2030 regulations upwards to a higher freq
Then there’s the top 5.8 section which hasn’t been touched for years. That’s the FWA sub band that allows 4W EiRP and needs a license to be paid for and for each end point location to be notified to Ofcom. These higher power licenses are not for WiFi and more for PtP and PtMP. Therefore the “5.8 UK Only” country code is fine as it is. It’s just the “United Kingdom” one that MAY be wrong.
Do please do discuss here. Unless there is rock solid evidence that something is wrong in RouterOS, don't report a bug to support. It might be that the law is ambiguous.

This is what I see from here https://en.wikipedia.org/wiki/List_of_WLAN_channels that would say 5745-5805 should be 200mw
and 5845-5865 should be 25mw My hAP ax is giving me 25mw on 5745-5805 as seen here.
interface/wifiwave2/monitor 0

             channel: 5805/ax/eeeC
    registered-peers: 4
    authorized-peers: 4
            tx-power: 9
  available-channels: 5500/ax/Ceee,5520/ax/eCee,5540/ax/eeCe,5560/ax/eeeC,5745/ax/Ceee,5765/ax/eCee,
                      5785/ax/eeCe,5805/ax/eeeC
It's very confusing thats why I didn't shove a Ticket in!

Any more word on this.
@normis not sure how to interpret what is being said in the above quote. Is 25mw correct or not?
Another example... https://www.msdist.co.uk/support/spectrum#5.8ghz

Edit: To be clear I am referring to SRD Devices, IE my hAP ax2

Re: Power tables for UK incorrect for 5725-5850

The information on msdist co.uk is outdated and doesn't include the newer SRD use around 5.8GHz.

The Wikipedia information is incomplete and doesn't include the "light licensed" outdoor use with DFS/radar detection for up to 36dBm.

Additionally neither of those are primary sources whereas the information from Ofcom is.

I agree with the information quoted from the trainer.

The license-free use is specified in IR2030/8/3 Annex 2 - https://www.ofcom.org.uk/__data/assets/ ... 203083.pdf - 200mW is allowed in 5725-5850 under this with the restriction "Equipment must not form part of a fixed outdoors installation when operating in 5730 – 5850 MHz. Airborne use is not permitted except within an aircraft to establish a connection with a station or apparatus within the same aircraft".

Their other document which I linked (https://www.ofcom.org.uk/__data/assets/ ... -RLANs.pdf) is not the legal specification but more a summary for operators, however it's still from the standards body and should be reliable information (and doesn't contradict IR2030/8/3).

There are some complications due to the overlap with 5470-5725 but I think it would at least be legitimate to change the existing 5735-5875/14 entry. The current entry seems both too restrictive (for power use) and not restrictive enough - firstly the existing entry permits outdoor use which is not allowed without the "light license" for fixed wireless access. Secondly, unless I'm missing something about how the table works, it seems to allow too high a frequency (-5875 when it seems it should be -5850?). So changing to 5735-5850/23/indoor (same basic requirements as 5170-5250) would seem appropriate to me.

(FWIW, though I haven't checked what tables they actually use, ubnt access points do allow 23dBm without DFS for these frequencies when set to UK).

Considering the overlap (5725-5730) with the 30dBm DFS band (5490-5730) probably the only sensible option is to keep the table as-is, I don't see that changing anything there would help anybody.

Considering the outdoor licensed use, having that in a separate "country" i.e. the "5.8 UK Only" that's available with the older drivers definitely makes sense - operators with the right license need a way to use this where permitted but it seems correct not to allow it by default. (It seems this is not an option with wifiwave2, which only has the one "United Kingdom" option).

At the time of certification, the EN 301 893 new version Draft was not yet published to include 5725-5850 MHz, so the EN 300 440 standard was applied. For new 5GHz products, EN 301 893 will be applied for the 5725-5850 MHz range. For the existing 5GHz AX products we are still considering the possibility of updating the 5725-5850 MHz range according to EN 301 893.
Our 802.11ax wireless products in the upper-frequency range are certified as SRD for unlicensed use devices according to EN 300 440 standards and can use only 14dBm power in the 5725MHz-5875Mhz. For more information please see the link below:

All understood, thanks very much.
Will keep my fingers crossed.

Old https://www.etsi.org/deliver/etsi_en/30 ... 20101v.pdf
New https://www.etsi.org/deliver/etsi_en/30 ... 20101p.pdf
I hope those are correct.

viesters said we are considering it so I assumed you guys were doing just that, hence my question.
Are you saying I need to direct the question to @viesters - support@mikrotik for a response ?

2 months and still we wait, I can only assume this isn't going to happen on the current range of products.
I want to buy more but it only makes sense if the product is in-line with others on the Market for the UK.
tik-tok,tik-tok.
