What is your current noise floor at with the ubnt sectors
About -80 at the AP.
The Cambium slant 45 sector might improve your noise floor by 3db but isn't a panacea. You really need better signal at the CPE to see better performance.

is that the Floor or peak?
i should say, does the UBNT get anything through? if they are kinda usable on UBNT they will be better with cambium, but a true 80 db floor, you need SNR for anything to be stable. the slants with help the APs and CPEs deal with the noise, but only some.
the more SNR you get, the better off. 3 points can make a huge diffrence. 10 will make a little happen, 13 will keep you up and 16 will make your subs not angry.... 20 and you'll see some good stuff happen.
do you have multiple UBNT 2.4 APs here? you may be your own worst enemy with noise. if you do, at night, shut down all of your other panels and watch your modulations and CCQs. if you observe a nice increase, change everything to cambium and enjoy the GPS. the GPS will remove all of your self inteference when setup correctly.
I have 25db snr at both users. Yes, I still have the ubnt rocket 2.4 right below it. Is running on channel 11 @10mhz so no prob
We'd been to this client several times over the last couple years, trying to tweak things. They were coming up to their yearly renewal anniversary - and were considering not renewing this year. I switched them to Cambium and here is the result.

try epmp1000 from cambium
UBNT- Pros: "Disruptive Pricing", Very Wide Range of products, Air Fiber, Semi 1 stop shop for Install supplies, Cable, Ends and Mounts. Fast RMA Process
UBNT- Cons: Scattered company direction with addition of solar, Only real support is in the Forum and this is ruined by the Alpha users in some cases assuming "You must know better", Virus outbreak twice now, Constant degredation in XM/XW line with newer FW's, No functioning GPS, Long turn around on announced products, Poor explanation of some features, Managment software and its endless beta......Honestly I could go on and on.
We have 3500+ UBNT SM's and 300ish UBNT AP sectors, and are preparing to do a complete overhaul to the EPMP line. And for now the only UBNT devices we plan to keep are the AirFibers due to their low cost and high throughput (AF24 series)
The thing that convinced me was the Feature set is working on deployment, No more announced product features that are not delivered on purchase. We were supposed to have GPS Sync (AirSync) in the Titanium line, this was a complete joke as the radios were complete junk. We should have jumped ship after their lack of product testing with the first run of tough cable. After less than a year we had this cable start completly failing due to the jacket discentigrating in the sun.
We have decived that its time to stop playing with the inexperienced and "Flashy" UBNT and move to a company who knows what they are doing, as well as a company who stands behind their products.

All great points and that is pretty much spot on as to why we are switching. I think we will stick with the AirFibers for the backhauls for now, and possibly even keep the 5ghz on ubnt for the time being. Hardest part for is, is being a small WISP with limited funds. I wish we wouldve started out with Cambium. Now we'll be stuck with a bunch of Ubiquti gear in the warehouse. We will be swapping our ubnt365 gear to Cambium ePMP1000 2.4ghz products soon.

We have been through a few generations of radios, Rocket Wave (A cheap board in a cheap box for $200), SmartBridges, Cyclones (Early Canopy), Canopy and Canopy Advantage, Tranzeos, Ubiquitis and Now cambiums. It is very hard to predict what will be the next line of gear that will fit best for you. Most of the products listed above served their purpose and carried us through to the next generation.
The main reason for my rant on ubiquiti, is that in the 20 years we have been a Wisp, the failures we have seen with Ubiquitis gear are kind of a stand out. I still have Cicso Aironet 500's on the network, because they still work well for what we need in those very few areas. Ubiquiti is systematically crippiling their equipment, at a pace that almost feels intentional. I still have some old Canopy 5400AP's and 5700AP's on the network running P9 and P10 boards. They work just as well as the day we got them and have been reliable.
I share the desire to go back and stick with Cambium, but the core issue is the pricepoint of Cambium's previously did not make for efficent expansion in rural areas. On a site with less than 100 people I cannot justify spending $5000 on a 450 AP and sector. Ubiquiti drove down the pricepoint and made the market more competitive. I am very happy that cambium in continuing their excellent support, manufacturing and product quality at this lower pricepoint.
---Phew-- Rant over.

On the flip side... I have NEVER seen a post or a topic heading (in this forum, the UBNT forum, or any other for that matter) that says... 'Convince me to switch away from Cambium'. or 'Done with Cambium, convince me to switch to Ubiquiti'.
That's saying alot!
Tandr06! Try out ePMP! It's a great way to start you down the Cambium path, and there's tools to help you migrate your legacy Ubiquiti M series radios over to ePMP. I think you'll never look back. We didn't!

We are actually in the process. 2 1000's in place sharing the same channel, And I am on it as well. I have always taken the approach that If I am unhappy on the service a customer will be as well. So far everything is going great. We have 40 Force 200's coming in to load up the sectors and see how peaktime bandwidth looks. We ran into the issue with UBNT gear that after about 15-20 customers are on an AP, there is a BW cap of about 25Mb (sorry if I did the sign for date size rather than transfer rate)
We are very excited, and have already decided that all of our new AP's/POP's are going to be Cambium AP's

LMAO. the only argument I've ever heard was cheeper upfront cost... and I don't think I've ever heard of any complany saving money in the long run. (from a provider standpoint)

can you please clarify, whn you put 40 custopers in 1 cambium AP what throuhput you are providing?
We provide
3/.5
6/1
9/1.5
15/5
25/5
On out ptmp and are planning on upping all of those plans this summer. We’ve got epmp APs with well over 40 and capacity to spare, and we’ve got a few at 30 filled with heavy users that are full. We run 20 mix channels most of the time and switch to 40 if needed. On 2.4 we use 10 mix and switch to 20 as needed.
Rather youve got 1 or 50 subs, you’ll get your speed. If all 50 subs hold mcs16 for the downlink, you’ll see 100 mbps agro avaliable. And stable latency

Chris - is this with 1000 or 2000 APs?
We offer plans similar to Chris... 6/1, 9/1, 19/1... and some custom mixes.
I just checked our highest loaded 5GHz ePMP AP... we have 40 subs on it. It's an ePMP 1000 GPS 5GHz using a 20MHz channel width, GPS sync, using a 75/25 split, and 5ms frame size. It's pushing around 43mbps on the downlink @ peak, and around 4mbps on the uplink at peak.
No complaints from anyone on the sector... still putting new subs on it :-)
We also have a somewhat over-loaded 2.4ghz ePMP AP @ 20mhz channel width, flexible/5ms frames... it has 53 subs on it. It's pushing around 41mbps on the downlink @ peak, and around 5mbps on the uplink at peak.
This sector has mostly lower end plans on it and we try not to put any new subs on it. No complaints from anyone on the sector, but we can tell through our latency monitoring system that things get a little dicey in the eve's.

its a mix.
the 2000 is the same data rates of the 1000 gear, the 2000 handles noise much better than the 1000. aisde from that, there is no diffrerence.
we still deploy 1000s out in remote areas and 2000s are always used in town. you can mix and match 1000 and 2000s on the same tower as well.

Jakkwb - in addition to Chris' awesome (as usual) replies and help - I'd like to clarify and add that the ePMP 2000 not only handles noise better, but also generates less noise in a better way than other radios. It has a dynamically programmed filter in it, so when you program it for a certain channel and width, the radio will hear very little 'next door channel' interference, but just as importantly, t'll also generate very little 'next door channel' type of interference. In other words - the filter will help make the channel edges 'square' as much as possible, and it can generate far less noise for your other 5ghz gear that can better co-exist on nearby channels. :)

Hello, first of all welcome to the community.
Use the GPS sync AP when you are collocating more than 1 AP on the same Tower or when you have two sites which are close with each other and they could interfere. You have a much better spectrum efficiency as tou can re-utilize the same channel at 180 degree (back to back ABAB).
On top of this you are going to have more REAL throughput and more SM oer sector, we have depkoyment with 100+ SMs…I would use ePMP2000 as it can e “upgraded” with beamfoarming antenna which will boost performances in the uplink in a RF envinronment with a lot of interference.
Last but bot least, you may want to elevate your network by using elevate sw license which willallow a UBNT sM to connect with a Cambium AP, also inthis case you can boost your network performances without replacing the UBNT SM… just test ePMP system and you will let us know…
Best regards
