Hi,
we have an ideal case in which we want understand the maximum capacity possible with mikrotik equipment:
26 CPEs (all ros >=6.30, 802.11n MiMo 2x2, SNR>=46db, all signals better than -70).
1 AP with RB711GA ROS 6.36.4, nv2, 20/40Ce, 5Ghz-only-n
In auto we can reach 30-35Mbps of sector throughput. If we set a fixed MCS of 12 we have the maximum o f 25-30Mbps.

How we can improve the performance?
What's the maximum reached with fully 802.11n setup that obtainable?

What's the maximum mikrotik performance in PtMP scenario? NV2 it's the best protocol or it's better to undo to 802.11n rtc/cts?

Upgrade your base station radio and antenna, it's cheap considering the clients number. Always use the best radio and antenna. I used only netmetal+19dbi sector or now is best to use mANTBox 19s.
I have 24 wireless clients and over 50 conected with cable on one mANTBox 19s with speed between 60-75mbps, protocol nstreme.

The problem is not hardware only software. (Poor PTMP implementation in ROS)

The problem with lack of bandwidth at PTMP is known.

However, MT does not do anything about him well about him.

For example :
Cambium at the PTMP sends the sector throughput with no problem.
(Their elevate solution will also be available on RB devices)

As you can see the problem is only in the software.

I would love to see MT fix it, but from year to year it is getting more and more interested in their LAN segment, not completely correcting this problem.

As you can see from the pictures, the problem is in hardware. If you have problems seeing that, put some glasses.I have posted an better solution and you didn't. You can clearly see that I am also using mikrotik hardware. Now I wonder, if I have clearly give an example with better results why you say that.
I don't believe ilnicchio will change all hardware because you say so. Cambium hardware is also more expensive. You should stick on the subject and try to help.

Inox, which type of antenna+cables do you use in your setup ?
It seems your signals are considerably better.
thanks

The problem is you are using a post-wifi system with all its flaws like

-the system is not only driven by AP but by CPEs too.
-the system doesn't know the "air" capacity so can't know the total bandwidth available
-as the above is not clear, there is no way enforce any real QoS on the wireless links
-wifi is not real TDMA system so don't expect to benefit of TDMA (well defined structure and timing, sincronization, uplink time correction, etc..)

. The better you get is 75 mega with 25 cpes and 80 Mhz (40V+40H) ? What about real QoS, fairness, etc..?

There are much more efficients wimax system which can deliver real 130 Mbps to 250 cpes with qos (internet, tv and landline independ flows) using only 4 x 10 Mhz and 1 polarity V or H, and it is not cambium pmp450 and is cheaper than epmp1000, have a look at Albentia

I use mikoritk for all the wired routing which is very good but for wireless access network, better use a wimax or propietari instead of a wifi/postwifi/etc...

It's all written in the post...

In fact is 40Mhz (20+20)

Specs say : 4 connectors N per external antenna, so I'm pretty sure is not just one polarity.

I have a very stupid question, it doesn't really make sense.

Does the simple queue type affect the modulation of the radio?

Somewhere on cambiums forum i read that they recommend setting the queue type to wireless default to avoid rate flapping and increase overall throughput?

Reason why I'm asking is because all my clients is running simple pcq queues, and I'm lucky if i get 20Mbps with 20Mhz on a sector, Disconnect all clients but one then only I see those kinds of speeds.

And if it reaches 20Mbps the ping becomes aids

Using mostly basebox 5's and 19dbm ubnt airmax sectors 120deg

Al the sectors is routed

In fact is 40Mhz (20+20)

Your screenshot shows layer1 modulation speed of 300 Mbps.. this is if you use 40 MHz channel wide, two polarization, so: 40V+40H..

Specs say : 4 connectors N per external antenna, so I'm pretty sure is not just one polarity.

That's right: you have freedom to configure the AP as per your needs. The best for WISP is the 4 N connectors to 4 panels pointing to the same direction or a 1:4 mixer and one panel to the same direction, then the 4 10 mhz radios are using the same polarity. Find 4 10 mhz holes in the spectrum and let the magic start..

I have 24 wireless clients and over 50 conected with cable on one mANTBox 19s with speed between 60-75mbps, protocol nstreme.

Can you please export your AP and one Client WLAN configuration here?
We can't get more than 30-35Mbps on AP with 40 clients, NV2, 40MHz
Do all clients support AC standard or you work on N?

We can't get more than 30-35Mbps on AP with 40 clients, NV2, 40MHz

What routerboard do you have on AP?

RB912UAG-5HPnD and RFelements 30st horn antenna using TwistPort Shielded adapter for RB
41 clients, CCQ 90-100%, speeds mostly above 270Mbps, signals mostly -40 up to -60, channel is clear (tried other freq but same results), other different freq. AP-s on same tower are -50dB or lower. Can't get more than 30Mbps total on this sector.
On others AP-s I have RB922UAGS-5HPacD + RFelements horn antenna and I got same results.

41 wireless clients are to many. Leave 20 and check the speed. If is higher, at least 50mbps, you must install one more sector.

Hi,
Using 6.39.2 in AP e clients, I can see improvements than 6.2x.
In noise environmet, for each AP, I can achieve about 15-30Mbit, with 20-25 clients. This, with nv2 protocol.

The surprise is nstreme, in the same AP we reach 30-60Mbit, so about double bandwidth than nv2.
But nsterme is unstable and some clients disconnect from AP without any apparent reasons.

So nstreme version 2 is worst than version 1. But Version 1 is unstable.

For each ap we must achieve about 70-100Mbit, if we want to stay in this business.


Waiting for Ros 6.40.

We have found lowering the client count to 20 or less fixes the NV2 speed issue. Setting NV2 TDMA Period Size to auto and making the Cell radius as small as possible also seems to help. We are trying Cell Radius of 3-5 larger than farthest SM.

We have overlaid ePMP for scalability so we are learning from it. In that world, you choose your range and make sure it is the same on all towers to avoid interference. Our towers are all set to 5 miles and this keeps one client from occupying too much time. We have also learned about link capacity. Other vendors make this a very simple thing to glance at and determine you have a poor link.

We still have 700 mikrotik units in the field and I am always looking for ways to improve the wireless performance. I am not bitter Mikrotik has not kept up in some ways, heck, we have done little upgrading in the last 3-5 years. That is pretty good for any manufacturer. My tech all love the Mikrotik modems, especially the wireless site survey being dynamic and very reactive. Mikrotik needs to get the U-NII -2A and 2C certified. This is the only way we as WISP's can stay in business is if we can use all the tools available to us. Not having all the frequencies is like saying your car can drive 35 mph, but you are only allowed to drive 75. Get it certified and fix the NV2 slow down. PLEASE.

Does anyone have experience with epmp elevate?

This is a foreign product. You might discuss it at the forum of epmp-elevate Vendor.

I have 24 wireless clients and over 50 conected with cable on one mANTBox 19s with speed between 60-75mbps, protocol nstreme.

I just got two mANTBox 19s to connect to 8 clients (4 on one and 4 on the other)
The clients CPE are using QRT5 mostly (just two clients have QRT 5 AC, one on each mANTBox)
Any tips on configuration? This setup is replacing 8 ptp links
What are your clients using as CPEs?
Do you think I can get 150mb/s on the qrt5 AC clients?
