So, we have been using Ubiquiti's XR3 cards for nearly a year now. We began our first demos in the summer of last year, and today have collected an ample amount of data on the cards.
Sadly, I have to say, this is, in our opinion, one of the worst products Ubiquity has ever released.
Though we conformed precisely to Ubiquti's instructions in terms of hardware, mounting requirements, grounding requirements, power consumption, et cetera, the XR3s have been one of the most unreliable cards we have ever worked with.
We originally worked with the XR3s, then later bought a batch of XR3-3.7s when we were told the original XR3s no longer conformed to the FCC guidelines. At $250+ a pop, it wasn't an easy switch. With our first batch of XR3-3.7s, we have nothing but trouble. Though the performance was great, at first, every card invariably would lose SNR to the point of eventually going deaf or just outright fail. One card after another would die in the field, regardless of the situation.
We sent our XR3-3.7s back, and were told by Ubiquiti support that our cards were being "retooled" and we should give them a third chance.
We received our cards back and put them back into the field, alongside our existing 5.x deployments. As always, we properly DC ground the equipment every time. At the customer sites these were deployed too, we even had electricians come on site to inspect the work and approve it.
Once again, for several weeks, the cards worked fantastic. Good SNR, great throughput.
Then, once again, they started dropping like flies. They would lose SNR and eventually give up the ghost altogether.
We've now spent over $2500 buying these cards and have decided to cut our losses and look for another 3.65 solution.
Considering that we have thousands of other radios deployed, at least 500 of which are high-power Ubiquiti radios, I am fully confident that we followed Ubiquti's recommendations to the T. I also am disappointed that they could continue to profess how well this card works when we have yet to get a single 3.65 link to remain stable for any length of time beyond a few weeks. We are in the process of now of selecting another vendor for 3.65 equipment. We have made ample use of SR2s, SR5s, SR9s, XR2s, XR5s, XR9s and numerous other ubiquiti products. Above all, these cards have been the worst, which is sad - because usually we look to Ubiquiti to give us an edge where other hardware can't cut it.
If anyone else has their opinion to share on the XR3s, let me know. As I see it, they are terrible cards.
