I have always shyed away from using 40Mhz channel due to interference in our area. The only gear I have tried with in the past was UBNT M series radios. Does the ePMP do pretty well with moderate RF interference using 40Mhz channels? 30Mhz would be nice compromise.... Maybe soon. Thanks
For PTP: in a noise enviroment, 40 Mhz just make it worst...
For PMP: didnt see much difference in bandwith.....

I know that Carullos has already voted - but everyone who agrees should go to the Ideas section and vote! Cambium prioritizes some of these things based on people's votes - so if you want 30Mhz channel widths, make sure you vote! :)

We use a mix of 20 and 40 mhz mode, the rssi requirements change a pretty good amount in 40 mhz mode, it’s not super noisy in the town’s we’ve deployed, but we do have a couple busy sectors in 40 mhz mode, getting 30 to 50% more bandwidth. The change in rssi requirements and background noise reduced the benefit. Having the option to choose in 5mhz increments what ever size you want up to 40 would be great, have an option for any situation.

Did you notice any improvement in total users and in quality of the service you're providing?
How much users do you have on one sector? What profiles do you offer?
our highest subscriber count panel has 59 subs right now, the highest purchased rate on that panel is 25x5 business plan, we offer up to 50 elsewhere. the performance is good, at night the traffic flow peaks around 100 mbps, frame usage gets in the 70s from time to time, but normally 20 to 50%. I'll have to check ping tonght when its gets loaded, right now RTT is 25 to 35 ms from my desk to one of those users. this pannel is in 40 mhz mode, the weakest downlink is 67 DB. voice services work just fine, several of these customers use our voip. really isn't any noise on this channel so all in all, very ideal conditions.
usually we only run 20 mhz on them, we bumped this one and 3 other pannels into 40 mhz mode, and changed a few units out for force 110s and 200s so the 40 mhz mode would code a little better, all in all we got the expected increase in bandwidth.

Thank you for your feedback!
Are you using 5ms or 2.5ms frame size?
Hope Cambium will “open” to 25, 30, 35MHz, I think it can be very helpful in a lot of situations!
Do you offer these speeds without limitations? Are you using any burst of similar?
we don't meter the data, we use that as a selling point. people are pretty heavy the first few months, but like any toy it doesn't get played with as much down the road. netflix and things that will always keep the load up, but there are ways of dealing with that too.

On both 2.4 and 5.8 ePMP we're using 20MHz channels on all APs and some BHs, 40MHz on backhauls that need it. (longer-term we upgrade those backhauls - our general BH upgrade 'hand-me-down' sequence is ePTP20MHz->ePTP40MHz->PTP600->6/11GHz)
We too provision a flat rate with no burst and no metering/limiting/overages. For about 50% of our coverage area the only other options available are cellular or satellite, both of which claim speedy service but can't consistently provide it where our customers live, and of course both typically meter usage and limit/restrict/charge overages.
Our base service is 4/1@$40, $20 more to bump to 10/2 if we can achieve at least 6Mbps down reliably, and no weekly/monthly limits. (except extreme cases - one customer pegged at 10Mbps down for weeks on end for example - so we do reserve the right to limit usage or reduce provisioned throughput if the sector is significantly impacted, but have only done so a handful of times in the past 6 years)

Hi. We've been wanting to figure out a quota limiting device too. We also find that 'most' customers use a reasonable amount - but for us, about 5-7% of our customer base use about 33-50% of all the bandwidth. So, most customers are about 20-50 GBytes per month - but the ones that go over - they go WAY over and use 300 or 500 or 700 GBytes per month.
So, we can look at our border router/firewall device and it does keep track per IP, butit takes time to manuallyextract those log files and to put them into excel and to sort them and to deal with all that. I've been shopping for a quota system, something that can either reduce speed past a certain X GB in Y time period - or even just a device/program that can email the top x% of users, or email the clients over X GB / month, or even just email us a ready sorted list of clients over X GB / month.
For us:
The top 15 clients use 10% of our total bandwidth. That is 1.3% of the client base, using 10% of resources.
The top 39 clients use 20% of our total bandwidth. That is 3.4% of the client base, using 20% of resources.
The top 54 clients use 25% of our total bandwidth. That is 4.8% of the client base, using 25% of resources.
The top 79 clients use 33% of our total bandwidth. That is 6.9% of the client base, using 33% of resources.
So - 92% of our clients are < 100 GB/mo. The other 8% > 100 GB use about 40% of all resources.

ninedd, if you’re using a RADIUS server and authenticate your users you should get a session database. From the session database you can get all the information you need to get the “best” users.
Using burst you can limit the speed of your customers if they exceed some parameters.
For example you could give 20/2 but if they make sustained download for more than X seconds (you’ll need some math) the speed is reduced to 10Mbps.
There is a request on Ideas section about that… At the moment you can manage it using an external router.
Using a system like that you should get good overall performance using 20MHz… I think

your usage statistics can bounce a quite a bit, for example a family with apple devices who all updated in the same short time frame, you could see 10 gig gone from that, or a dad who updated windows 10. a kid who bought a game on line that's 30 gig. unfortunately there are more and more things that can cause wild swings in a homes usage patterns. for us, the single biggest marking tool we have over the big providers is simply support that.. there is a difference of an abusive user and a heavy user though.
not saying data limits are wrong, or nessasary bad. but its a great marketing peice to not have them. having a way to limit WAN traffic for some of them can go a long way with streching your resources, like getting a netflix box in your rack if you can qualify ( https://openconnect.netflix.com/en/delivery-options/ )
and doing the same for other major content providers so your resources are now local and major reduction on your WAN needs.
we had at one point considered doing data limits and the response from the couple dozen subs we talked to about it to get there feed back was less than pleased to be gentle about it. we changed our approach to try and bring what we can into our racks to reduce load, like netflix and deployed a much heavier edge network, (4 5ghz EPMP, 4 2.4EPMP and soon testing our some dual band sectors to save on leases) rather than trying to stretch what we had already deployed, we tested out the idea of deploying very heavily in a small area and the response was amazing, we've since made those changes network wide and our sales have never been higher, our customers have never been happier and overall, our load per customer ratio really never changed much, but what did change is the amount of customer refurrals we've gotten. they've sky rocketed. of course everyone experience is different but for us, going the opposite direction has greatly improved our network and our profitability as a company.
