Does RouterOS support Xtreme Range2 802.11b/g 600 mW mini-PCI ? Because we are about to buy dozens of them for routerboards …
and does anyone used these cards before ? how do they perform on routerboard ??
thanks
Oh yes RB supports Ubiquiti XR Mini PCI cards…
I tryed sr2, it is very good mini-pci. I am thinking xr2 is good too.
Yes, but be sure to remember that the XR2 & XR5 both need to utilize lower TX power settings.
If you have MT using XR set with TX values of 17db you are really outputting 27db.
You will need to calculate your AP sectors/omni db’s along with the XR cards to come up with the legal limit
of TX power.
Also you will notice that to run full power will provide less throughput than experimenting with the TX power to find the happy medium between signal level and throughput.

I’m not so sure that is accurate.
I tested two different XR5 cards yesterday with a power meter from Berkeley Varitronics, and and a 17db setting was only yielding like 22-23db power output. Setting it to 22db was required to get it to output 27-28db. Setting it to 28db or even slightly lower actually made the cards “click”…which was weird. Setting it to “default” power seemed to only output like 19db.
The whole offset is rather annoying, and hopefully Mikrotik can update the software to report the XR cards properly.
SMA
Ah, this is great cause for concern, if what he says is actually valid that is. It would be great if others can elab on this.
Ps. it would even be better if Mikrotik can automatically/properly set the power of the cards in a simple manner. I.e. Including the offset within the tx power option.
Regards.
actually there are no regulations in my country regarding the output power .i dont wanna use amps cos the only amps we have are 2400lx from rf linx and they do a lot of noise. Thats why im seeking a high power mini-pci.
xtreme range2 600mw cards will be used on 3 minipci routerboards (forget their model number), and they will individually fed 3 120 degrees 20db hyperlink sectors.
What im seeking is a good sensitivity with minimum noise.
Also on the client side; rootennas will be used with 2 minipci routerboards. One will serve the customer via ethernet ,and the other will repeat the Basestation. both minipci s will be 60mw (or 100mw). Repeater antenna will be a small dipole with ufl connector.
Is it a good configuration or im missing something ?
also is there any other higher power mini-pci s that can be used in Basetations to feed 20db hyperlink sectors ?
thanks
click sound on minipci cards … means usually the card cannot draw enough power from the host computer …
ive observed this with various brands …
I’m just going by what Ubiquiti states in its spec sheet, if you want to contest that take it up with Ubiquiti.
Is your intention to utilize each client device to also extend the coverage area of your sytem using 2 MINIPCI’s in the client device?
As far as I know the Ubiquiti XR cards are the most powerful, quiet and feature the best interference rejection.
Yes my intention is to increase the coverage area. So every customer will become a hotspot generator. XR2 cards will be used in the main basestations (not customer side). Are they enough powered to feed hyperlink 20db sectors ? anyone used this conf before ?
Are there higher power mini-pci s around as well ? like 900mW or 700mW ?
just seen you topic , i would like to hear you expirences with xr2 in a crowded area in famagusta! doesnt it make more noise than usal and caused problems ? on the other hand, check again the tx regulations! there are regulations in tx powers in cyprus! dont put yourself in trobule 
thanx for ur reply oz_gr.. XR2 performs good but not as expected.. Noise floor is the highest (-99dbm) on the XR2.. Where usually I have -92…
XR2 is good in my opinion although its running on a RB532 with another several other High powered mpcis…
Are you living in famagusta btw ?
the reason for noise is the amp. on the cards; more power & more noise !
no im living in nicosia; i just swapped my WLM54s with SR2 ; i dont prefer use more than 2 cards on 532s if its acts as a part of backbone; more m-pcis ; more resource load; thus can make system to respond slow; bdw dont forget the offset issiue of these cards on rb; dont burn them!!
yes i have several SR2 s aswell but i should tell you XR just outperforms all the cards i have tried till now even in noisy environments… card is set to default tx rate so offset issue wouldnt bother me…
Currently working on WDS bridging on the repeater sites.. Hope it will perform as expected…
well as long as you dont have too much load i guess these guys runs without problems
XR2 performs good but not as expected.. Noise floor is the highest (-99dbm) on the XR2.. Where usually I have -92…
-99 is LESS noise than -92, not more.
opps sorry for misunderstanding.. its vice versa.. XR2 is the one having -92… other cards -99.. i think its because of the noise that XR2 have on other cards..
Anyone else see the same things? I’m looking at replacing a number of cards with XR2’s and XR5’s and I’ve debated with just sticking to the SR’s instead.
Someone said something about the noise floor difference between the SR9 (-97) and XR9 (-94) possibly being that they are simply more accurate at reporting it.
Any opinions?
Dont consider the values i have mentioned because there are 3 cards on the RB532 + 502 in my case..
2x R52H
1x XR2
So cannot depict the noise factor.. Im not isolated…
Even in that situation, XR2 never drops customers like the other 2xR52H cards…
