5Ghz Channel 149 Usage in GB

Hi,

 

I'm looking to use channel 149 for a point to point bridge (as recommened in the P-to-P guide). I have a license to use the frequency for the site(Ofcom).

 

When I select the regulatory domain country code for GB it does not allow me to use that specific channel, it doesnt give me the option to do so.

 

Is this normal behaviour?

Re: 5Ghz Channel 149 Usage in GB

UK generally follows ETSI regulatory AFAIK.   In Europe, the upper band from channels 149-165 is not permitted.

 

No Aruba equipment is approved for use on those channels in ETSI countries.

 

Channels 100-140 are approved for outdoor use.

 

Channels 36-64 are indoor only in ETSI countries.

Hi,

 

Thank you for your response. I have asked the regulators for some clarification on this.

 

In the UK you can purchase a license to be able to use the Band yet the ETSI say you cant?

 

Also, Ireland is an ETSI Member yet It does give me the option to use those channels when selecting Ireland as the Regulatory Domain on the Controller config.

 

Many Thanks

Hi Ian,

 

I double checked with our Compliance team.

 

No Aruba product is approved for use on channels 149-165 in UK or Ireland.   If you have a SW version that is showing these channels are allowed, this is a bug and almost certainly will be changed in a future release.

 

Compliance tells me that this band is only approved for 25mW anyway for license holders, which is completely inadequate for outdoor PtP links.  

 

Regardless, we support and certify all of the allowed  unlicensed channels in each country in which we operate.  The only licensed band we support is the 4.9GHz public safety band in US and JP.  No other licensed bands are available.

 

I recommend you deploy using channels 100-140.

Hi,

 

Thank you for the swift response. Can I ask one more thing please. Could you tell me what your interpretation is of the following information from the websites below. Three are UK based Tech companies and the other, the UK regulator for Communications (Ofcom)

 

http://licensing.ofcom.org.uk/radiocommunication-licences/fixed-wireless-access/

 

http://www.solwise.co.uk/wireless-5.htm

 

http://www.4gon.co.uk/solutions/introduction_to_5ghz.php

 

http://www.digitalairwireless.com/wireless-blog/recent/quick-guide-to-5ghz-uk-part-1.html

 

They all state the use of Band C, 5Ghz at max 4W EIRP in the UK with a License (Purchasable from Ofcom)

 

I'm still waiting on a response from the ETSI on the matter.

 

Many thanks for your help/advice on this. I dont mean to cause any arguments or anything like that but from what I can tell I should be able to implement this solution. Could your compliance team have a look at these, specifically the Ofcom details and the IR2007 located here and let me know what they advise?

Thanks again, appreciate the help.
