I have tried to switch 2.4 Ubnt over to EPMP, not having much luck so far. Really need a 10/15mhz channel size to to work with instead of 20/40

Just use a 5ms frame size and you'll have access to 5/10/20/40MHz channel widths in TDD mode. There's not a huge difference in latency between 2.5 and 5ms.... and you also get about 10% more throughput with 5ms as a little bonus.

Wow. I feel kinda stupid. How did I not know that? Must be the heat. Thanks Eric for enlightening me.

Ok, so now that I have that fixed, here is my setup. I have a Ubnt Rocket M2 with the Ubnt sector with RF-Armor on it (channel 11). On a 10mhz channel size. I have 18 users on it, constantly complaining about slowness. I have an EPMP mounted about 5 ft above it, also on a Ubnt 2.4 sector with RF-Armor (channel 1).Both have same output power, same antenna gain, same distance setting, both aiming the same direction. Users are from 3 to 7 miles out.
Next week I start changing folks over. Cannot wait to decommision this Rocket.
Can someone share about what bandwidth I should be able to pass on a 10mhz channel size? I have my first Force 200 operating.
~50Mbps would be the max theoretical on 10Mhz. I see about 30~35 down and 6~7 up I think usually on PtMP installs with 75/25 split in the real world.

Ok, so I now have two customers on this, one at six miles other at 8, they are sitting at -76 and -73 (the six mile has more obstructions).
As I said, I am using a Ubnt sector with RF/Armor with this. Would I see any better numbers with the Cambium sector instead?
You would see a better noise floor in theory becasue the cambium sector are 45 degree slant and better noise floor sometimes means better throughput. Plus the cambium is a 90 degree sector which would give you a little tighter patter and better front to back ratio
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.
@jakkwb wrote:About -80 at the AP.
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
