XR3-3.7 not working as expected

[neofast]

I've got a 10 mile link in, which is basically clear, no serious fresnel zone encroachment, and using the Arc W 18 db panels, I"m getting -82 on one end and -78 on the other. No amount of reaiming seems to improve the signal.

Also, I have set the power setting to "default". If I put anything in there, it either drops in signal, or refuses to pass any amount of significant data. In Star-OS, the "threshold" seems to be about 17 or 18. Trying to set t he power above that results in data throughput falling to almost nothing. (signal doesn't really improve, either).

I was expecting this link to have a low -70's RSSI, and I'm really between 6 and 10 db below that.

Any suggestions? The part that's bothering me most is the unequal RSSI between the ends. I generally find that only if the radios have unequal output power.

These are the only 3.65 in place there, and the only XR3's I have.

Hey Neo,

Shoot me an emailt to mike@ubnt.com

Thanks,

I answered, but haven't heard back... This is really, really important to me right now.

Hey Neo,

I did not see the email. Please resend and also CC support@ubnt.com

Thanks,

I have a link with the same characteristics. Could you let us know what's going on here?

Mine is working so it's not life threatening at this point! It's 3.2 miles absolutely clear los, no Fresnel interference. It will ONLY connect in 10mhz mode, and I can only get 24Mb/s/2 tx rate. I have -74 to -76 dBm equal on both ends and was expecting much better. CCQ runs mid 90s.

What's going on?

Hey Diesel,

Shoot me an email also to mike@ubnt.com and Ill see what I can do.

Thanks,

mike

I put the link into production this afternoon (sunday) and after carrying traffic for about an hour, the link dropped and then eventually came back, but with one side seeing the other at -90, instead of -78.

So, apparently, the transmitter died in one of the radios.

I am so totally NOT impressed.

After paying serious dollars for these things, they perform like garbage and die fast...

Dude

you need some bigger antenna's. we have a 6 mile link with SR5's and we are running -58 to -61 V3 1.3.23b
those antennas are to small for a 10 mile shot

I happen to have a couple 10mile links on 2.4ghz, which happens to have a little less path loss than 3.65ghz

these are my links

10.7mile - 24db grid +XR2 (600mw) / 24dbgrid + XR2 (600mw) = -64db to -69db

9.7mile - 24db grid +R52h (350mw) / 15db Sector + R52H (350mw) = -67db to -70db

-----------------------------------------------------
Doing the math for your link, I'm showing around 27db fade margin, with a link of around -68db

Have you checked: Lightning Arrestors, Pigtails, coax, crimps and voltage?
All of the above have caused crappy links in my past - upon replacing said crap parts, BAM it works! :)
Which is the reason I will probably stop using the R52h, the uFL pigtails SUCK SUCK SUCK SUCK SUCK SUCK!!!

ok.. sorry for the rant. Luckly for us the XR3 is mmcx...

Well first of all I have found the return loss for the 3.5 - 3.8G Arc antennas unacceptable when using them for the XR3 FCC part 90. (<12dB) I searched for quite awhile for antennas that would perform well on a network analyzer, I purchased several from different manufactures, well the long and short is I did not find an antenna that would work well. So I ordered some antennas from overseas, modified them and then had their engineering dept. modify them for Webhiway. We now are importing them tuned specificly for the 3650-3700 frequency.

Order a set and watch the XR3 jump to life!

I'm running 5180 through a 5.8Ghz only panel antenna and lost like 20db! Tuned antenna's DO make a HUGE difference on your signal gain. Also, make sure both antennas are the same polarity. If one is horizontal and the other is vertical, you will lose and exceptional amount of signal.

I have had success going 7 miles with XR3s with reasonable bandwidth. I am trying to develop a way to go 8-10 miles with more bandwidth.
