Hi

Some friends told me that Ubiquiti's XR7 are excellent option for MK.

But are they going to support it? And if so, when?

I would assume it already works. It should work the same way as an XR9. You select a 2.4 ghz channel and use the frequency chart to convert to 700mhz. Has anyone ever used an XR7?

I have a public safety office that was asking me about wireless access to their emergency vehicles and they asked about 700mhz. I didn't know what was available for antennas and if the XR7 would work for them.

Any ideas?

Nope. I'll run it by Ubiquiti as well.

Might just buy two cards and antenna's and test. The cards are about $270 each.

Has anyone actually tested these yet? I'm still interested in how they perform and what kind of antennas are available.

I've got the card installed, but need to mount the antenna (bout 230' up).

M2 Inc sells a 14Dbi yagi. We use quite a few of their m2-14's and 17's (900) with pretty good success.

Mike from UBNT says they work fine. Should start testing in a couple weeks.

Dont you need a license to use the 700mhz Frequency? not just just checking. Also how far will it go? Is it really that much better than 900mhz.. I can see where you would get away from interference though... However costly expense to do so. -Jordan

Not that I'm aware. Should go, based on terrain and elevation about 30-35 miles.

XR7 is not supported
i have 2 cards, the client doesnt registed with the AP, i tried all the frequencies on the chart, nothing worked.
i contract MT, they told me they need to test it, and they dont have cards.
i contacted Michael Ford from ubnt.com, he said he will test it and come back to me, since then i never heared from him!

let me know if anyone got this thing working.

Haven't got my antenna's up yet, but that is gonna suck. Those cards were $270 each + antenna's.

Any more results since the last post about this? I'm still curious.

Very poor results. Quarter mile away and signal was -87. Connected but browsing was very slow. Removed antenna from tower and will test elsewhere.

Worked great in my test office, but once deployed I couldn't get much signal. Antenna was about 85 foot up. Same SR9 can hit about 4-5 miles pretty good.

Interesting, what type of antennas were you using? Noise floor? What was your exact configuration/setup?

Re: XR7

The antenna's are M2 14dBi Yagi's (Horiz Polarity). The noise floor was about 100. No other 700 stuff anywhere near my equipment. Can't remember what channels we tried, but I know we tried several.

Has anybody else had any success with the SR7?

The M2-Inc 700 MHz Yagi does not have the right bandpass characteristics for the XR7 card. According to M2-Inc the antenna, "The pass band gain has been designed to roll-off quickly above range limits to prevent receiver overload from other services just above 750 MHz."

You need a different antenna.

How did you get RouterOS to recognize the Ubiquiti XR7 card?

It recognized it just fine. Just had to use the channels UBNT said to use.

I could try other antenna's but don't know who makes them. When I did my testing it was in my lab using paper clips. That's what we use for all our tests.

Thanks Greg;

Here is the pdf for the 14 dBi Yagi from M2Inc.
http://www.m2inc.com/main%20html/714AISPMAN.pdf
You can see that antenna is designed to drop off quickly above 750 MHz. Another thing that happens as you get away from the design frequency is the radiation pattern of the antenna changes and you loose more energy in the standing wave (return loss increases).

We bought a different antenna from someone, I am not sure who. The boss does the buying, all I do is spec them out.

You may find this parts list from DMS useful, though I don't think they sell small lots.

It is weird. I installed two XR7 radios today in RB433AH boards and RouterOS did not discover either of them.

I'll take them out, clean the contacts and try again tomorrow.

Again Thanks

Hi xbaha, i have 2 XR7 Cards installed in 2 Mikrotik 433AH with 3.25 ROS, but 2 card not register, i have tried all 2 ghz disponible frequencies. Testing is made in laboratory to 2 cm distance but without antenna. You have another idea???


Thanks.


Tony.

2 cm distance but without antenna.
these two things are both very bad ideas :) attach some kind of antenna, and increase distance :P

Ok Normis, i have attached a Antenna to MMCX and now work fine.

Where i can purchase Yagi 760-780 MHZ Antennas??? Now i must made test on the Way!!!!!!

See this http://1wirelessway.com/index.php?main_ ... cts_id=128 but vendor is not in Europe.

Thanks.
