Hello, I have two new XR3 cards, I have a question,
these cards, what models of table in the PDF datashet file are?
I buy these card in a USA provider, microcom.
I like to know what are the specific frecuency range conversion for these cards, I mean the channels allowed to work good, and what channels are turbo!
I use DD-WRT software installed in Avila Gateworks 2348-2, works good, in channel 136 and channel 140 when I have the equipments with the antennas front each other. When I separate the equipments like 2 kilometers, I have not signal, and I believe that maybe is the channel configuration.
I need a superchannel version to use these cards??? or what regulatory domain can I use with these cards?
Thanks
Marco

Hello Marco,
These cards use a 2GHz downconversion with XR3. You will need access to channels between 5400-5700 to have access to the the 3GHz spectrum. This does indeed require the superchannel license to be most effective, but as a start you can try the country code Armenia.
Thank you,
Mike

Hi Mike,
I've heard about down conversions before, but I'm not entirely sure how they work? I'm working on an XR3 setup with the 3.5GHz.
Thanks!

Another question for you Mike,
Where can I find antennas for the 3GHz and 5GHz radios? Especially the 3GHz. I've checked some of my favorites (Bluewave, maxrad), and they don't seem to be manufacturing anything specifically for that freq. What is your experience using other (2.4/5GHz/?) antennas?
Thanks

Hello Andrew B,
Down converting the RF mean taking and existing 5GHz Atheros 802.11A chip, and changing the output frequency to meet our goals.
So most operating systems will detect the XR3 as a 5GHz A card, but by selecting certain frequency ranges you will achieve the desired 3.5Ghz output. So our card has a "2GHz Down Conversin" So selecting the 5 GHz range of 5500-5700 will produce an output of 3500-3700.
Thank you,
Mike
p.s. You can check with any of our distributors/resellers and they will be able to guide you to a 3GHz antenna.

What is a superchannel license and what are the benefits? We are currently licensed for the 3.65-3.7 GHz spectrum and are currently using Redline and Solectek equipment. We are expreimenting with the Mikrotik RouterOS boards and have purchased four XR3-7 cards.
Again, would this "superchannel license" help?

Since xr3 is seen as 5GHz card you'll need access to channels in the 5GHz spectrum which are normally restricted. Superchanel licence allows you to use all freq xr3 supports.
If you're using Mikrotik, ros versions >4.2 include superchanel lic for free. (4.3 is buggy so I would wait for 4.4 though)

I must not be seeing something...The freq for 3.65 thu 3.7 are not listed. (5.65-5.7)

Hello,
Select the Superchannel option and they will be.
Thanks,
another question, XR9 also uses the same technique, if I have mikrotik Superchannel license will I also have the benefit of more channels at 900 Mhz?
