Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

Hello!

 

I recognized, that outdoor AP's (365 / 375) with installation type set to outdoor and country code austria, are hopping to channels above 140.
These channels are reserved for radar in Europe/Austria.

 

Shouldn't outdoor flagged AP's avoid this channels if the cluster is set to the correct country code?

Firmware: Instant 8.6.0.5-8.6.0.5_75979

Management: Airwave 8.2.11.0 and central

 

For my understanding, this is not the expected behaviour.

Thanks for your input!

Re: Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

Have you checked to see if you have the correct DRT file on the IAPs, or if you can upgrade them and check available channels again? 

 

What do you get when you run the "show ap allowed-channels <country code>" command? That should breakout what you see on an indoor vs outdoor.

That does not match austria.....

 

I can try to update the cluster and check if it is fixed.


Until now, I also not checked if there is known bug regarding regulatoriys in the 8.6.0.5 code....

Yea thats strange. Maybe a TAC call?

Re: Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

The newest DRT Version (DRT 1.0_76935 AP) was released on Sep 9, 2020.

On the other hand, the actual IAP 8.6.0.5 was released on Released on Jun 29, 2020.

 

So, I updated the DRT File.
But the channels 149-153 are still listet as allowed outdoor channels.

I will open a TAC ticket.

Re: Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

As far as what I have access to, those are valid channels (UNI3), but at a very low EIRP (25mW), so not very functional. it may be that in those cases, that those channels be excluded from the regulatory profiles where those channels are not desired in your deployment due to the lower power.

Re: Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

Hello!

 

If these channels are used on indoor AP's, it would not be a very big problem.

But, these channels are allowed for outdoor AP's.

 

And that's the problem!

We have a central MSP customer, in the middle of an austrian City, operating an outdoor AP.

It took only two weeks after deployment until a radio measuring vehicle of the federal radio authority (I hope this is translated well enough) appears, and the customer and us got a warning.
We got a deadline to fix this, because we interfered with a weather radar (in austria, weather radar is starting with channel 144).

If not, there is a penalty.

 

So, it is very urgent to fix the DRT File.

We checked some IAP Clusters, it happens very often that the AP hopps to channel 149. Especially in the near of an Airport.

 

Now, the most of our Customers opperating outdoor AP's, are MM or Master/Standby Customers.
I have not checked them until now.
But I'm convinced that the controllers acting in the same way.

 

The "workaround" is, to overide the ARM channel selection by now.
But this is not a glorious way for us, because well known SOHO vendors do not interfere out of the box with our federal wether radar.

Re: Outdoor IAP uses not allowed 5GHz Channels for regulatory domain Austria (Europe)

Jerrod Howard and Onno:

 

It's right that it is allowed to transmit at 25 mW on this frequences.
But the Telecommunications Authority was able to receive the SSID on channel 149 from a few crossings further.

They also checked if we changed the channel, and confirmed that we changed to 140.
Intresting is, that the signal strength on 140 was lower than on 153 or 149!

 

This leads to the thoughts that the allowed limit of 25 mW on 5725 and above are exceeded.

 

Is it possible, if the Radio strength at the ARM settings is set to 12 - 18 dBM, the DRT file limit of the frequences 5725 and above gets overwritten?
