XR3

RouterOS Wireless Networking

Hi all:
Did any one tested XR3? Does M.T O.S Support it?

The current frequencys supported by this card are in the “FCC testing” phase (cannot be used commercially and require a testing license)The 3650-3700 MHz band is in the process of being availalbe to WISPs. This is an exciting prospect. However the exact contentions for using this band have yet to be defined and I would advise not using it unitl the FCC determines the exact usage contentions.

To answer your question, I believe the Mikrotik router OS will support this card due to the universal compatability with the Atheros chipset (same as the SR9 cards). I have not tested this since I am not interested in this untill the exact stipulations have been laid out by the FCC. I would bet $$ though that it would work however.

From what I’ve read of 3.5GHz unlicensed, it requires registration and cannot be use for comercial purposes yet, just testing/personal use.

I agree with palindin74, wait a bit and see if its legal.

If you’re not in the US, I guess it doesn’t matter.

All the UB 3.5GHz equip is, is altering the frequency of Atheros chipsets. Should work just fine.

We’re outside US. The customer got a license to use it from Goverment here.
But the issue is, how is this card working with Mikrotik O.S?
We need someone who already test it!!!

I want to know that too,

And I don’t want to listen if in usa or in the moon you can’t use it :imp:

Every one knows what is legal in his country.

We just want to know how it works

Stable or got some issues

Thank you

they will work just fine, you will need conversion table, to know, what frequency you actually using. as this card will show up as 5GHzx or 2.4GHz card. But it will work in that correct frequency range.

Hi Janisk, Hi all:
Mikrotik told me that O.S is not yet supported this card. I should receive at the end of May.
But I hope if any one tested this card with M.T O.S. We don’t need surprices…
Also about the driver, can we ask UBNT to provide it"linux driver"?

Hey Guys,

Xr3 works fine under 2.9.38 and 2.9.41.

Xr3 uses a 2Ghz frequency conversion, and is detected as a 5Ghz cards. So you select the corresponding 5ghz channel.

I.E>5.5ghz = 3.5Ghz

I have tested several links in the lab and in the field and the performance of the card is really good. Throughput graphs are flat (over 5km) and signal quality is really good, since this is based off of the XR architecture.

I have been testing and qualifying the card for the last 60 days and have had no problems under MikroTik.

Thanks,

Mike

Do the XR3 radios support channel widths smaller than 5MHz (like 3.5MHz or 1.75MHz)?

10

Sounds good, just waiting on the FCC to get their game together, hopefully sometime this decade.

11

you haven’t tested it with 2.9.42 or it was not working fine for you using that version of the RouterOS?

12

Hey Guys,

Ya i just update a couple of my Routerboards (112/532) to 2.9.42 and the cards are working just fine.

Jarosoup,

No we do not support channel width’s smaller then 5mhz.

Thanks,

When is the card shipping in samples / volume?

Hello Stephen,

Please email me at support@ubnt.com as I cant/will not use this forum for advertising :slight_smile:

Thanks,

Hi Mike-Ubiquiti:
We have one question, how to show the customer that the output frequency is 3.5Ghz.
We know that it is using frequency conversion, but we have to show it to the customer that the output frquency is 3.5Ghz “or 3.4Ghz”.
Is it possible?

I can’t select the 3.5 frequency range. Do we have to buy a Custom License from Mikrtotik to use a public frequency? Anyways I did not get XR3 working.

you either need a custom frequency license, or you need to change your country to austria, where 5.65-5.7ghz is selectable

18

Thanks that helps a lot. Are we able to select the public frequency in austria? I believe its around 3.4-3.6 (public).

Let me ask this question. Is the XR3 limited to 5MHz worth of bandwidth or do we still get 54mbps?

20

with this atheros chipset having good signal levels and clear channel @5Mhz you should get around 22-24 Mbits real throughput , while best wimax station out there wont reach the 14Mbits @3.75Mhz :smiley: Thanks to Atheros, ubnt and Mikrotik guys and sure the ppl buying there stuff to support them,lol
