I know other companies has problems with 400 mW because of EMS noise they can't pass FCC, can imagine that this 28X will have even bigger noise :-) Then what is the energy drain?? Imagine if you need to use 2 or 4 miniPCI radios. Power consumption then will cause even more overheating than SR5 has. This could be a problem

What US supplier has these cards?

Do they work ok with MT?

Hey guys,

We do have FCC Modular Cert,

These cards work great on Mtik as long as the voltage is there. They do draw more current then Sr2 or Sr5.

Thanks,

Hi Mike from Ubiquiti. Thank you for making great products like the SR2 - the SR2 with Mikrotik is a great combination.

What is the advantage of the XR2 vs an SR2 on 802.11b, or 802.11g?

The receive specs are the same? If so...is it just the 600mw vs 400mw (about 1.5db I'd guess).

Yeah, I saw that. But I still have the same questions, and it would be great if you could sum it up:

What is the advantage of the XR2 vs an SR2 on 802.11b, or 802.11g?

How about:

-- No diversity switch to burn out (lower odds to drive, climb);

-- Better ESD durability (another roll of the dice to drive, climb);

-- Better temperature rating (yet another coin flip chance to drive, climb);

-- Better rejection of out-of-band signals (not going to necessarily save driving and climbing, but may help with sleep);

-- More time and money to eat pizza, drink beer, sleep.

Mike,

Have you had a chance to test those XR-5's in real world situations? We currently use alot of Trango for our AP's. We use MT for BH's. I'm working on get the owner to switch over to MT totally, but i need some real world people that have used both and know the differences or can give me real world examples of how well they worked and can be used.

How would your new XR-5 compare to lets say the Trango 5.8 AP?

I didn't see that on the spec sheet, how do you know of this feature? :P

I'll try one or two out when the local supplier gets them in. The only time we use higher power is when using a very low gain antenna - ie to get the maximum vertical coverage by using a little 4dBi omni with a 28dBm radio. Although there are maximum dBm limits that should be observed.

Unfortunatly I can not do a comparison for you, as I do not have expierience in real world situations with Trango euiqpment, just in a lab type enviroment.

But the Xr-5 versus Sr-5, in real world situations provides a much cleaner/robust link.

Hi Mike,

I see on the spec sheet there is an alternative frequency range in brackets - can you tell me more? Is that the full operating range?
We're desperately looking for cards that'll do the upper 2.4GHz to lower 2.5GHz...

Hi Mike,

I appreciate the fact you must promote the mini pci card from the company you work for. I have problems with you avioding answerring important questions asked about the 600mW cards. We need the answers to make purchase decisions. Now again i asked the question again;

Apart from the increase in power why should we buy the 600mW card as against your 400mW cards. The 400mW card a fully feed tested and come out tops. This is a simple question, please answer it and do not refer use to the datasheet , i and i am sure the rest of the guys have read the data sheet long before it was annouced on this site.

You could of course ask sales@ubnt.com instead of beating up on a UBNT engineer who has the courtesy to frequent this forum.

UBNT has been incredibly open and responsive about their cold weather SR9 problems. I have NEVER seen a company handle this kind of problem as well.

Mike hangs out here listening for tech issues involving his product.

He is not and doesn't pretend to be a sales guy. MikroTik is not keen having sales people pitching their technolgy on this forum for perfectly understandable reasons.

Hi ghmorris,

I just spent some minutes trying to determine what was wrong with asking a tech guy to shed more light about his product. I am also amazed that you would refer me to te sales without bothering to answer the simple question.
No one has these card yet, no one has tested these card yet, is it not logical to hear how this card stand with the well known and field tested card from the same company; the 400mW cards, is this too much to ask?

Mike's company is great one but you must note that we shoud all be frank on this forum, the key question has not being answered.

Hi dbostrom,

Point of correction; you quoted tem out of context, and this will be my last reply on this topic.

Mike's original reply;

Hey guys,

Here is a link to the Data Sheet with specifications on the Xr2. Easier then me explaining them

http://www.ubnt.com/downloads/xr2datasheet.pdf

Thanks,

Mike

Now the point i raised was why could Mike not just mention at least one or two key capabilities that stands 600mW above the 400mW other than just saying go read the datasheet on our website; the next issue is real world application, does the data sheet tell you real world application?
A similar question was asked MikroTik about the CM9 and the RB52 and MikroTik handled the question beautifully and with real world examples (my view is the RB52 is the best card to use for any 5GHz link, they have NEVER failed me this is not a typho , NEVER failed me for any link).

Like i said i will not discuss this post again, a simple issue is being overlaboured.

I was asked if I had any real world experience with Xr5. All testing I have done has been in the lab environment. I have been trying to not step on MikroTik's toes as this is not a vendor forum, and was hoping other people would chime in with answers. I do not want to be seen as a sales person.

To answer your question, the reason for going with the 600mw version, is distance/link quality at low signal levels. Also the units resistance to interference is better, along with noise suppression and the ESD system.

This is from a test report that is bieng published soon
High Signal – 45db


Xr5 – 16.6Mpbs @ 54Mbps Sr5 – 16.5Mbps @ 54Mbps
Xr5 – 10.3Mbps @ 18Mbps Sr5 – 10.2Mbps @ 18Mbps

Medium Signal – 65db


Xr5 – 16.3Mpbs @ 54Mbps Sr5 – 14.5Mbps @ 54Mbps
Xr5 – 10.2Mbps @ 18Mbps Sr5 – 10.0Mbps @ 18Mbps

Low Signal – 85db


Xr5 – 8.6Mpbs @ 54Mbps Sr5 – 7.7Mbps @ 54Mbps
Xr5 – 10.0Mbps @ 18Mbps Sr5 – 6.7Mbps @ 18Mbps

This setup was a Radiated setup using attenuators to achieve the desired signal level. This is also in a noisy enviroment in the heart of the silicon valley.

One other thing to note, i only frequent this board about once a week, depending on how busy I am. If you have any burning questions that need to be answered right away, you can always email us at support@ubnt.com

Thank you and hope this helps :)

Thank you Mike - this certainly looks like a well engineered product. I look forward to seeing it shipped (April?) so that I can play with a couple of them!

One technical spec. that eludes me from the data sheets is the RX performance (intermod, out-of-band rejection, image rejection etc.). Many "carrier class" installations share tower space with noisy environments and in my experience most of the miniPCI cards designed for laptops/notebooks can't cut it. Since your product appears to be designed "from the ground up" as a carrier class radio, can you shed any light on the RX performance?

Thanks!

Mike thanks for all the effort on this forum.

My question to you or somebody else is why would we buy the SR5 with the XR5 available now? It seems to be a much better proposition so have you not just ended the life of the SR5 to a degree?

I am going to venture and say distributors are feeling this way too. The SR5's and SR2's have dropped in price dramaticlly.

Most of my testing in the lab is done on MikroTik's and so far I havent seen a problem with them.

Also i have run tests on Avila boards and Gateworks boards running IkarusOS.

Hey Planedriver,

shoot me an email at support@ubnt.com

I will get that to the Hardware Engineer's to see if they can give you exact specs.

All commotion died on March 14th? weird.

Anyway, we've got some XR5s working out there in our network. These XR2s and XR5s demand a lot of power (from routerboards). So far, we've had single units in RB532-A (64MB). Didnt work with any others (112 or 532). I dont remember if it did work with 133c or not....I'm guessing not.

On top of that, we are trying to setup a PtP 5.8GHz link over about 18 miles. One end has SR5 in it and the other with an XR5. Nstreme on; link acts miserable. drops every now and then (in terms of seconds). Turn Nstreme off, connection seems to be stable....(pipe: about 5Mbps - both ways).

Wonder if it's the incompatibility (glitches) between the two or just not enough juice for nstreme-ing.

Suggestions welcome.

we've got 2 XR5's that just arrived last week that we're going to be doing some testing with, we are planning on putting them up on a 18mi link to replace SR5's that on occosion see large unexplained drops in signal (~15-20dBm) for anywhere from 5 minutes to 3 hours, the link operated great otherwse, low -60's most of the time, and 2ms across the link. We're running these on 532a's so any input you have from your testing would be great.

Hey Engineer,

Did you find anything out about this problem. I have done compatibility testing here in the lab and havent run into any issues running Xr5-Sr5. Also I have tested 2 XR cards back to back on RB532@24V with no problems. Please shoot me an email so I can help you.

Thank you,

Mike

TWO XR5 ON a RB 532

Mon Apr 09, 2007 10:23 pm

Anybody tried two ubiquiti XR5 on an RB 532 ?
Power requirements ? Something special ?
Did you use them on the same frequency ?
Any interference ?
I'm going to put on 4 couples of xr5 on 4 rb532.

Thanks

Carlo

Mike/Demaric,

Troubleshooting; replaced board and XR5 on one end and it's been stable since. RB532-4A with 48V POE. About 15Megs Up and Down (simultaneously).

Thanks for your help, Mike.

Could be, what power supply are you using. I looked at the spec of the RB532(2-4w) and the XR5's (6w) each. According to the manual there is 5amps or about 16.5w watts available for the cards. So if you are using one of the 48v 20w supplies you should be fine, although you could run into issues if you have a very long run of cable as a 90m piece of cat5 has a resistance of 5 ohms (1 pair of conductors) and consumes a few watts in wasted energy too... around 1.5w. So even with a 20w supply (48v) your getting pretty tight power wise at close to 18w any thing less and you will have problems for sure.

Info on xr5

Tue May 22, 2007 8:35 pm

Hi Mike-Ubnt,

we have now an xr5. Our BTS have 1 sr5 and 1sr2. Work fine and regulary.

We have change sr5 with a new xr5 , but no special things ....

So , 2 questions :

first , in MT 532 with 2.8.40 , how tx power setting for max performance ? ( actually we have set to 28db )

second , Is necessary connect ground of minipci to chassis ?


Thank's for answer.

Marco

Hello Brasil,

I always recommend leaving the Tx power setting to default. If you decide to change it, just remember that the Xr5 has a 10dB power offset. So if you set the MTik to 18dB you will actually be outputting 28dB of power.

And I always recommend grounding the card.

Thanks,

Mike

Hi Mike,

Any luck on your testing with MT 2.9.43 & frequency upgrade yielding the rest of the upper Atheros 2.4/2.5 channels?

Is the offset the same on a XR2?

Sure.

Read this http://www.ubnt.com/downloads/SRXR_power_offset.pdf official doc from Ubiquiti.
Bye

Re: Ubiquiti 600 mw card out for 2 and 5 Ghz

Sun May 27, 2007 6:48 pm

Mike, could you please explain the power offset some more? I don't recall seeing any mention of this feature on the datasheet or other cursory reading and I am worried I might be overdriving some of my SR2 / XR2 cards. For close installs, I have been reducing the transmit power so as not to "shout" at the AP. I used the "all rates fixed" option in MT on an SR2 and set it to 19dBm. If the offset table is correct, this means I was overdriving the card by 3dB? Well, not according to my tests...

I got a signal on the AP of -71 dB with the card set to 19 dBm. I then changed the TX power to default, which in theory should have reduced the transmit power, but after doing this the signal on the AP was -63 dB! Thinking perhaps I was introducing a ton of noise with the high rate, I then manually set TX power to 16 dBm which should be the same as default. The signal on the AP then went to -75 dB. The only thing I can think of is either the offset table is wrong, or the "all rates fixed" option in MT accounts for the offset on SR2 automatically. Could you please shed a bit more light on this? Thanks.

r1ch: sorry to get off ur topic, but if you are talking an indoor install to laptop wifi users, my extensive experiences shows me that you DO want to shout at the AP to make up for the very weak RX sens. on teh Laptop end.

R1CH,

-63 is a VERY good Signal.

-64 is my taget signal on any install I do, particularly backhauls, and still very nice for client installs.

If you acheive -63, do not try to power back.

I realise -63 is good, this is just one one of many CPEs that I happened to do the testing on. In order to reduce noise for other users in the area, I like to cut back transmit power where the install is close to the tower and the full 600mW is not required. It just seems the power offset thing is maybe not quite as Mike described based on my results above.
