802.11ax

Thu Jan 31, 2019 9:45 pm

Is MikroTik planning to make some new antennas with 802.11ax protocol?

Yes sure, you can become the next unpaid Beta Tester

ARM Hardware is now avaible for 13 Month, and does not work as aspected....

ARM works very well. The only issue I know of, is lack of full compatibility with legacy Nv2 protocol.
Any other problems?

Guess a lot changes in 7 years

"you can go with either of them, nstreme and nv2 is going to be faster than vanilla 802.11, and if you are using only RouterOS wifi clients, that is good option to choose.

the fastest of all three would be NV2 in normal conditions."

yes, this is what the word "legacy" means. it means we added nv2 to improve 802.11n. It was not designed with ARM or 802.11ac in mind. These new systems have no benefits, as they are already superior.

It is fair for MikroTik to fix an issue with a standard that later gets updated and moves on past the fix.

Totally agree. I just think that documentation needs to be updated to reflect that

The same problem. NV2 is slower and have other issues. Nstreme is also slow. Best is 802.11, but this is not suitable for p2mp :( high ping, jitter and lossability

Mikrotik should not allow nv2 to be selected on 802.11ac hardware.

It is clearly broken, why even give the customer the option of being disappointed

They need a user experience manager who thinks about these things. Hard to find super techie and yet a client advocate in the same person.

If nv2 compatibility vs. older hw is the issue, why not just call it nv3, change the timings and whatever is needed for it to work on ARM and clearly state it only works on the new hardware and it's incompatible? If the compatibility is in the way, fine... but at least have a new protocol that's stable between ARM devices.
And if designing new protocol is too hard for P2MP, at least have one for P2P links that works...

You can buy 802.11ax routers on the shelf in retail stores already, yet zero communication from Mikrotik about their timeline... this is rather worrying.

It's only one month until the EU MUM. Maybe they will announce some 802.11ax gear.

What we need is NOT yet another incompatible P2MP link protocol, but implementation of some standard or at least interworking with what other manufacturers (especially UBNT) do.

To do anything with P2MP protocols we need compatibility between manufacturers, at least between UBNT and MikroTik.
Now we can do only standard 802.11 because there always is at least a MikroTik client on UBNT AP and vice-versa.

LOL... Good luck with that, I'm sure manufacturers are really thrilled to publish all their secrets so they can make less money... this is simply not going to happen.
Only possibility is if TDMA is part of the future official 802.11something specification.
And it's a good question why this wasn't done long time ago... it's not like TDMA protocols like nstreme, NV2, AirMax are new.

802.11ax claims to do the job:
https://www.qualcomm.com/solutions/netw ... es/80211ax

ofdma gives frequency slices to cpes
Uplink resource scheduler handles media access (So what is different to TDMA).

So the TDMA/compatibility discussion might be gone ...

We had the same issue in amateur packet radio and it was solved in the nineties. The solution was called DAMA and I think it is much like NV2 and AirMax, maybe less a few of the special optimizations.
It is unbelievable that 25 years later there still is no 802.11xx standard that covers this and can be implemented by every manufacturer.
Then at least you can have rudimentary collision avoidance on a P2MP link, even when the manufacturer-specific protocol works a bit better.

Does 802.11AX still not include such a system? I would think that an "all new High-Efficiency Wireless protocol" would... the "collisions due to hidden terminal" problem should be present even in indoor networks at increasingly higher frequencies...

Those networks might still be wireless, but will become more and more NFC to a point where it won't be possible to have any obstacle between radio partners (except for their housings) and thus there won't be any "hidden terminal" due to lack of signal coverage.

DAMA does not require any special arrangements at the radio layer. It just polls the clients (at the link layer protocol) in a ring to ask them if they want to send data.
It is my suspicion that both NV2 and AirMax do the same thing. However as they both invented their own protocol they aren't mutually compatible.

Of course in a new system one can solve it at the radio layer, but the polling solution can be used with existing radio hardware.

I thought the movement is towards beamforming accesspoints (with the associated advantages of MIMO) which means that all clients clearly hear the accesspoint, but do not hear eachother at all.
That is the same as with a P2MP outdoor link setup.

Yeah, beamforming is buzzword of the moment. However, there's still EIRP limitation and with all that free air pathloss increasing with frequency and specially with inability to penetrate or refract the obstacles (a moving human body can become a huge problem) ... I'm just not holding my breath.

And you really believe that Mikrotik will support that feature from the beginning, there are so many things missing @ac Hardware, so don’t call for new Chipsets, they are not able to support them

Wave 1 Missings:
- Output Power Managment
- Spectral Scan
- Channel sizes

Wave 2 Missings:
- no wave 2 features available

What’s about 802.11k, 802.11r and 802.11v, we need that in the EU for every Wireless Network in
Government Places / Meeting Rooms etc
Ask Mikrotik for those features and you hear silence
At this point there is no future for Mikrotik Wireless, not Indoor and not Outdoor, only at
low cost markets

This is quite troubling situation, as for WiFi4EU you need these features and no Mikrotik device supports them. So even if you love Mikrotik, you can't use it. And these are often big projects, paid partly by EU money. If Mikrotik had suitable device, they could sell good amount of them.
Instead all that money is spent on competitor products and as a result they get more R&D money to release even better products, meanwhile Mikrotik is stuck in the past with limited R&D budget unable to catch up. We can only hope it's actually not this bad...

I have throughput problem even with mibsbe in some cases, especially for client upload, or with NetMetal + mANT I only get 50Mbps throughput when with other vendors I get 200Mbps, but I think it's a mANT problem.

Just setup an Omnitik ac, connect some clients, and do a ping to the MISPBE Clients and the same time to the ARM Clients, Mode 802.11
You will See high Pings on ARM without any reason, impossible to deliver Voice Service over this Hardware.

@Normis Are you able to talk about 802.11ax ? At least what MUM to look at ....

There are chipsets of your suppliers out there: https://en.wikipedia.org/wiki/IEEE_802.11ax#Silicon. So I guess you have something in your lab and as you did with 60GHz you might want to do some interesting move there ... hopefully

Would be great if Mikrotik released at least minimalistic roadmap, something like: 802.11ax work in progress, expected ~2019Q3
Same for Wave2 and other features. No need to be more specific, just confirmation of "yes, we are really working on it".
This might be enough to delay investment and buying of competitors products. Currently you wait, and wait and wait and nothing is happening, no news.
So you end up buying other company products, only to see Mikrotik release it month later. In the end it only hurts the Mikrotik sales...

+1 for this. Normis and colleagues at Mikrotik, we need a roadmap for wireless LAN products development for the near future. Mikrotik is my favorite and default goto device, but one can barely plan for the future as you guys hardly talk of what's in store for the future! It's by guesswork and keeping on hoping for the better. Put up a roadmap ASAP!!

You can buy 802.11ax routers on the shelf in retail stores already, yet zero communication from Mikrotik about their timeline... this is rather worrying.
802.11ax isn't finalized yet.

You must be young.

The routers on the market are "draft" ax, as in public beta. Compatibility with the final product is not guaranteed.

ax is going to have better contention protocols and MUMIMO than ac, but not by much. Wave 2 with MUMIMO has that capability and the built in contention control may interfere with nstreme and nv2.

I imagine that ax is going to be a bit of a bear for MT to adapt to. Once they get it going it really does sound like a match made in heaven, however, it has so many WISP related features built in I believe it is going to cause them problems. They'll probably disable most of those features in the initial version and slowly roll out updates with hardware support for the built in contention control.

The routers on the market are "draft" ax, as in public beta. Compatibility with the final product is not guaranteed.

Most likely chipsets will do the job already:

I am not realy young ;-) But we need some upgrades soon.

ARM works very well. The only issue I know of, is lack of full compatibility with legacy Nv2 protocol.
Any other problems?
Normis - re: ARM works very well. The only issue I know of, is lack of full compatibility with legacy Nv2 protocol.

If Nv2 is a legacy protocol, then how about Mikrotik create a next generation TDMA protocol. Call it Nv3 or something.

I hope there will be no next manufacturer-specific TMDA protocol but rather an established standard that all manufacturers follow and that allows inter-operation.

For 802.11ax, there should be no need for any custom TDMA protocol, because standard itself already have what you can call NV2 on steroids: Not only it's TDMA, it can also assign different parts of spectrum to a different users for each timeslot... over multiple MIMO beams. And all this is handled by hardware chips, so with great precision and no requirements of main CPU to do the timing (and cause issues like with NV2 on ARM).

I've been quietly following MT for many moons now, but I'm honestly clueless what is their business strategy. If this is thier tactics, they totally got it right, though!

Maybe MT focus on the last-mile and some backhaul? Maybe ISP edge? Or CPE/SOHO? Or maybe amateur projects? Or maybe stability before features? IDK...

All I now is that it's 2019!!! 5G is being deployed even in Eastern Europe, .ax mainstream devices are almost flooding the streets these days, IoT is already wrecking havoc in some places, more and more spectrum is being made available worldwide. And I'm just sitting here, waiting for MT to release some modems above Cat.4 or at least improve compatibility with other vendors' ones.

Guys, calm down. Chill a little. Forget MT Wireless. It’ll be like a breakup with a girl: hard, painful, expensive at first, much work, but you’ll get over it.
I did. I miss RouterOS superior management and features, since I hate web GUIs and limited console configuration options, I sweared much, missed mac-telnet, torch, l2 and l3 firewall, super flexible bridge and endless other configurations.. but at the end of the day what matters the most? Right! User experience!. As long as it works ok, you don’t really care any of that above mentioned stuff and have your chilled margaritas :) Let MT sell wireless eq in developing countries where 2Mbps are still called broadband. We need much more advanced stuff and get used that MT fail to deliver it, so let’s just jump the boat and stop bragging.. :) P.S. .ax alone won’t save them, IMHO.

This really made me ROFL. :lol:

It's sad but true, though. I now only use MT in a few very niche projects. Shame to watch such potential going to waste...

Dear Forum, Cheers to All. May your packets never queue. I've personally not had any problems with ARM, or NV2 as long as you remember that NV2 doesn't work with poor link quality causing re-transmissions. In terms of the performance, it seems to work fine and the faster the processors the better. I really like the dual or quad core processors on the wireless wire and hoped every new unit had that much horsepower. I'm using all 802.11AC radios, and provide my clients with speeds between 10 and 40 mbps x 5, expecting to get no more than 15 clients per device PTMP. I can get 180mbps over the air all over town and 300mbps tcp on the bench one direction with AC. FDX is 100 TCP on bench, or 70mbps outdoors real world. I'm not sure what the rest of you are doing. There were some optimizations I learned early on (through the forum) to make things work right.. and it would be nice if mikrotik enabled some of those things by default as it seems to improve performance. Namely, the multicast helper(for NV2), interface queues (multi-queue ethernet default), ethernet flow control (on). I've been happy with the product and with NV2 compared with no NV2. the key with NV2 is that you can't hookup clients with crappy signal, anything better than -65 is ok, but I prefer all clients in the -59 or better range. I configure all nv2 aps with 70 down and 30 up, typically a 2 or 3 ms, and turn hardware retries down to 2 rather than 7. All minor improvements that boosted overall performance, in addition to a current and stable version of firmware and routerboard software. We have used the Mtik Dish and Netmetal AC to spotlight areas from the tower, for instance a neighborhood with 200 homes 20 KM away from the tower. Then I've started to use the DynaDish and i'm pretty happy with the beam width as it trims out the local interference better than the QRT. Re-transmissions kill NV2. I am very hopeful for 60 G, and have been using two links to backhaul from tower to tower downtown for over a year at 350meters with no issue. (I strapped one to an old Canopy dish, and omg the signal is perfect if you have the patience to align it.) I am hoping that the new wireless wire dish will get an integrated AX radio so we can have a primary and secondary radio set in each link to allow for redundancy to the tower. (hint hint, nudge, nudge, wink, wink) I eagerly await the integration of new standards for AX, to keep us small WISPS ahead of the curve. My clients and I are happy with Mikrotik products and the versatility of such a powerful OS. If MTIK can help with the Wireless wire dish + AX radio, us small wisps can actually provide reliable service for 50 clients from one site and 5 GB of over air TCP data, allowing us to compete in small neighborhoods with the existing Cable operators.

I'd like to address your comment in step-by-step:
- yes, you're right, the RouterOS is increadible OS with it's instruments, management, capabilities, etc.
- NV2 from ~6.42 has been updated and poor signal/quality clients no longer drag down the AP performance that much, also higher number of clients on AP doesn't reduce the overal capacity of AP anymore (though they still could have done better). Together with TDD ratio, I call this NV2 update one of the best since the NV2 introduction. It actually works.
- Hardware retransmits doesn't have an effect on NV2. It was mainly used back in the day for Nstreme.
- CPU power on AC CPEs is not everything. Higher performance CPUs mostly benefit on APs, especially when there's such magic like GPS, beamforming, TDMA scheduling in play. Newer generation MT CPEs with >=600 MHz CPUs are usually enough.
- Sure, if your network is all on AC, you get some benefit from that. But I bet you're on pretty clean RF over there, and furthermore you use some client-oriented devices for APs to filter out the interference. Because on MT, most advantages of AC come only in the form of higher modulations, which again are useless in noisy areas. You can use narrow beamwidth horn antennas to achieve the very same result and to have some more professional solution. We all think of various solutions to survive, so we've all been there, done what you said. And managed MikroTik wireless to live up to this day.

Now let's get back to reality.. In this 4G LTE and comming 5G era, we have no chance to compete with current MikroTik products. We simply cannot. Sure, 4G is not available in some areas, but soon it will be when equipment rotation will start happening. To buy us few more years we need seriously reworked AP devices from MikroTik. With backward compatibility of course. Because competition is already far ahead of MT, and they showed us that it can be done - MT's AC cannot outperform their 11N. And they also showed us that MT client devices are quite good and capable. So not everything is lost for MT yet. I remind MT few key features they somehow really need to work on: nearby channel filtering, proper GPS-sync for freq reuse, asymmetric fixed downlink/uplink datarate support, little more improvements in NV2 to call it NV3.

With "we", you likely mean the small WISP that offers internet access to a couple of local paying customers using a WiFi network.
That is of course a niche application that works only in places where it can compete with better solutions like you mention.
In a highly populated area with large demands on internet bandwidth, such solutions never have been viable, no matter what make of equipment you use.

But it is not the only application for MikroTik equipment.

Code: Select all


I'm not so sure 5G cellular is going to be the "bees knees". Cell companies still have to roll out their hardware and i've got no faith in 5G given the current results of tests done in Dallas, LA, and Chicago. It won't work through windows or much very well and i'm anticipating they will be nothing more than little wifi hotspots and it's mostly hype to generate more sales. I've been installing for them for 14 years since 2.5 G cellular. They use overpriced hardware that doesn't seem to perform well enough to justify the additional expense. The only thing the cell companies have is the ability to output at 300 times more power than ISM band WISPS. They have a huge budget, make record profits, and i'm sure they are lobbying to try and take over the 5Ghz to 6gHz band to further create more of a monopolistic situation to boost bottom lines and reduce competition from highly motivated small WISPS.

There is a bunch of interference in this valley. In Reality there are only 3 major tower sites where everyone and their brother co-locates to serve the 70-100 thousand inhabitants of this 6x10 mile valley. Spectrum and other local wired ISPs have most of the market share. However there are many people on the fringe who cannot use the 4g Network to operate, have low speeds from other ISPs, and the major players have no intention of providing services to the outlying areas, ever - without massive grants funded by further inflation and debt. I personally own a network that I paid cash for every component, after working for Cell companies and building their infrastructure and being beaten down by soulless huge spreadsheet management firms posing as capable construction management firms that pinch most of the profit and shed any responsibility.

In any case 802.11AX will likely perform as well or close to the expected performance of a nokia or alcatel or huawai base station. For the same price we can deploy 20 times the sectors and throughput with Mtik.. We already have a 5G style link performance with 802.11AD for a fraction of the price. I really don't see much better performance from 4G than 802.11AC in terms of realized throughput. You pay the additional premium for better quality, higher powered components, with redundant power supplies, HVAC, and proprietary algorithms for TDMA that makes the medium more friendly and adds tons of latency. Since most providers enabled Unlimited access, at times my service is worse than dial up at times. Fact is that there are not enough towers, and they are not motivated financially enough to add outside of the core community centers.

If you've got a small WISP, build out a site, hold the root lease, then sublet to the Cell companies for 2K per month and you can win both ways. Or start putting fiber in the ground, and use your tower assets to fire licensed links to small fiber loops in select areas where you already have a handful of wireless clients.... that's what I'm doing. And it's been very successful. I do feel us Small WISPs can fill a niche, and many folks would rather support a local company anyway than promote the corporate grab for concentrated power.

I don't understand al that whining abt MT not making it into the future...
I am a small 750 clients WISP in an area where at least 8 other providers are around.
60% of my network is now full 'ac' (with a load of 'arm' devices) and I run on most of my 40+ sectors plain 802.11 which still everytime again shows better results then NV2 (or nstreeme)
Yes, I tend to work with signal levels close to -50, anything higher then -60 will be up for an antenna upgrade or it must be on a small (<10 clients) AP.

Our plans are offering 50Mbps down, 5 up to our clients and so far we have a very satisfied customer base.
In one area to compete with fiber we have a Netmetal with 40+ SXT's and SXT'sq, all working in 802.11ac and we give them the 100/20 Mb plan...
The frequency even overlaps some other but in careful picking the 'pilot' channel it all works to satisfaction.
Due the pricing of MT hardware we can always compete on price with any of the 'bigger' providers and although we loose some at times (and get new ones back) we managed to have a stable and satisfied client base.
We use several 60Ghz links for the short backhal to satisfaction (ditched some Metrolinks over it. Unreliable and too costly). These 60Ghz works so good I tend to forget them in the update cycles we maintain since they simply always work.

Yes, MT has a learning curve and indeed, a lot of fine tuning can be done, and needs to be done. We also tried Mimosa but for the money we spend on that I regret I didn't wait a year and would have no all the same done with Mikrotik for much less money..
All my competitors use ubiquity but I see them struggling to get the same done as us and we see several of them trying other brands as well. So they must have their issues too...

We have 4G LTE since 2 years in our region, but to be honest... it sucks.. Where speeds very good the first weeks (way over 100Mbps, even in a moving car) that fell considerably the moment more people bought themselves 4G phone and started to watch their video over it. (And these same clients still want 'fixed' internet to their home).
For the rural area (but high housing levels) I don't see 5G going to deliver the promises neither. Their simply won't come enough towers to the region.

MT as usual takes time to bring new technology and needs even more to mature their ROS when the hardware is finally there, but for the price it makes still a economic model to wait maybe a year to do the same as any high level product but for a fraction of the price.
For instance eCambium with their new ePMP4000 product line is claiming higher CPE levels per AP but the price is also several times higher. And in the transition process you need to run two networks side by side. In the anology of taduikis this means you still need to keep the present girlfriend with all its merits while investing in the new one. And yes, you get screwed twice! They 'interfere with each other and we all know what that means! :lol:

For small WISPS with small budgets the niche market can still be profitable but you have to be smart and stick to the wife once chosen. If you are loyal you have to hope she (MT) is too and delivers us new hardware to sustain our marriage into the future!

I don't understand al that whining abt MT not making it into the future.............................................. our marriage into the future!
Don t know what your available Spektrum is. We need/use gps sync to get the performance we need.
This is Spain... we use like all the others, that what is available.
Let me count, in total some 40+ AP's and at least some 25 backhauls. All in 5Ghz, most 40Mhs, many 80Mhz. All in a range of 15km...
Count my blessings. Every sector I have at leasts overlaps some other radio and vice versa in some corner of our valley. It's a big puzzle to find working freq's.
I know some operators even work 'out of band' in 100% illegal frequencies, some in 'grey' area (legal but too much power....) etc. just to keep the business going. Nobody denounces since everybody will see it then boomerang back.....

Yes, MT's sync sucks. I tried it several times but it simply is worse then without. But then again, we even have 4 Mimosa AP's that we tried to do sync and we could only manage to get 2 pairs out of the 4 AP's to work seamless. The others interfere with each other.
Some new provider entered this region a year ago with two towers with each 4 sectors, synch'd but each full 80Mhz channel, ubnt radios. It caused problems for some of my sectors so shifted some frequencies and now even have one of my sectors at distance but serving the same region. It sits in the middle of their 80Mhz and I am serving my clients with 40Mhz...The 802.11ac protocol works fine, don't know about theirs.... (All my signals to clients have to be -60 or better. And ping times are not very stable but below 40ms which is ok for a P2MP setup. I do always make sure my "C" channel ('pilot channel'?) is not the same as theirs though. The 'ac' protocol should work 'around' it.
We don't do VOIP, it's cheaper to give clients a terminal with a simm of one of the cell operators. We have a deal with them. They bill us wholesale and we bill the clients. Problems are theirs and we still make a couple of bucks per month on these clients...! Clients don't care if this is VOIP over our wire or Cell (with VOIP over cell). As long as they have a phone line with a geographic number assigned they are happy.
Bulk of our clients use video and IPTV and that works absolutely fine for them. Our 90% issues come from home Wifi.

When I started this WISP 18 years ago the spectrum was sort of desert. Now it's more like the battle of Austerlitz with too many parties and even the big army's (cell operators with their G4) make a mess with low coverage and illegal towers.... It's a war out here and if there would be any arbitrage 80% had to shut down and probably the richest (or the best 'friends in high places' = money) win. That is not me..... :-(
As long as we all earn our daily bread and people get their internet we will survive... And MT makes it possible! :D

Is there no telecom authority in Spain?
Here in the Netherlands we get calls and/or letters from them when an outside AP operates on the indoor (low) channels, or on a radar channel without using DFS, or outside the band.
Operating too much power is a bit harder for them to prove. But on several occasions they actually mapped the frequencies of tower-mounted APs.

There are comparable rules/laws. But very different efforts enforcing this. And there are different capabilities (my guys here have an anritsu but bad antennas). I follow rules to avoid problems. And I see the sense in these rules. (Almost, as these DFS rules are not practicable (lead to service interuptions at times) and no vendor has a good/correct handling).
One reason we move away from MT Wireless is: You cant follow the rules and keep the service going smooth.
There is still no ATPC. MT follows the rules and set TX-Power to the lower powerlimit. So if you enter correct antenna gain you end up with low TX-power.
So WirelessRudy operates illegal for sure to get reasonable Signal. He will not call regulations as they may shut him down. You cant enforce a rule you break.
I gave up on asking for ATPC for a long time and decided to use a vendor which is able to implement it and allows me to operate with higher power according to the rules. If everybody would follow rules MT had implemented ATPC long time ago. But there are too much cheaters and "amateurs" (which do not see the benefit of ATPC for their self-interference). So they dont care.

Re: 802.11ax

Wed Aug 07, 2019 1:01 pm

I am from Holland too and know the differences between the two countries. But where in Holland the rules are strict, and policing is everywhere, in Spain only those that get denounced by others get a checkup.
It's with housing rules, business rules, safety rules, traffic rules etc. etc. You can basically do what you want until someone doesn't like it/you and denounces it/you.
In Holland a policeman seeing something that could be considered illegal or just lacking documentations would trigger him to ask/investigate it and if found something not in order shut things down.
In Spain the police doesn't do nothing if somebody has not been asking him to do so.... (Well, traffic nowadays is slightly different). Not seldom that same police officer (or major, civil servant etc.) is not having all papers for his house/reform/whatever rule in place himself...
In Holland you have dedicated civil servants that are looking around if all that falls under his area of interest is having the proper licenses etc. In Spain most townhals haven't and even at national or provincial levels they are ample.

I always stated, and still think this is valid, that if all WISP's in Spain tomorrow would work according regulations, the day after 60% of fixed wireless clients wouldn't have no more service and by the end of the month 50% of all WISP would go bankrupt...
Frequencies 'out of band' or in the lower band, too high signal levels (Spain doesn't even allow directional antenna in the free 5Ghz band or you have to tune the power output that low nothing comes out of it anymore!) is more the standard way of doing things here .... off course nobody openly admits, but I see what I see when I run a scan....
I tried Mimosa in regulatory domain and almost all my clients disconnect. Same with Mikrotik. Or signals become that bad that no more proper service can be delivered.
Running DFS? Well, we have rain radar and an approach path of one of Span's busiest airfield over our valley. If we have to work in those frequencies that have no influence of these two I am left with almost nothing. If possible (Mikrotik) I switch it off. In Mimosa we cannot but in using 'grey' frequency at least it doesn't harm the network every minute. Now the network just goes down for almost 10 minutes when we reboot the Mimosa AP.. I can live with that....
Basically all my competitors, even the national operating ones, use frequencies and EIRPS way out of the regulations....
Also, once I've red an article stating that in Spain probably some 16.000 (!) communications towers on the top of mountains are lacking any form of documentation or permits and not seldom are protruding local as well as national laws.... Many towers it's not even known who owns them....

Our reason to work as much as possible with frequencies inside the allowed band is not out of abiding to the law... more that I don't want to give my competitor too much sticks to hit me with in front of a judge...
If tomorrow all housing laws would be enforce I would probably lose half of my clients too... this is rural Spain!

Guys, perhaps you heard about a tiny vendor called Hew Pac Ent I think. They started selling pre-802.11ax hardware since last year. After 1 year they finally published an updated roadmap for 802.11ax software features: Image
So you hopefully understand that making software is hard for a smaller vendor especially also for that one coming from a small cottage on Aruba.

Not that hard for a vendor doing this stuff for a longer time now like MT. They are used to take Atheros chipsets and build their gear based on this. They managed to build this 60GHz gear so I guess a basic implementation of 802.ax would not be magic for MT. Tuning this for WISP usage is a another step which might be harder. This heavily depends on developer kits from chipset vendors and what is already done by them.

Time to Market would be rather short, If you take the design of the RB4011, add 2 antennas for 2.4 GHz, remove the QCA9984 and the R11e-2HnD and put in 2 QCA6390 so finally can achieve a Quad Radio 802.11ax access point with 2x 2.4GHz and 2x 5.0GHz. This would be something no other vendor currently offers.
Also Reinis will have a working MU-MIMO firmware ready when this device arrives.

@WirelessRudy,
Do you still use Mimosa? Is it woth deploying in interop mode?
I still use is yes. But am not investing any further in it. I can do almost the same with MT gear for a fraction of the costs.
Also, further developments in Mimosa go slow. MU-Mimo promised years ago only since a few months available if you are ready to invest in new AP's. My previous ones are still not paid off.....
Mimosa 'interop' mode? Didn't use is since the initial test case I had. It worked fine but excludes GPS sync. Something I do need to run several AP's in 80Mhz band in dense urbanised area.

I am waiting in better performing sync for Mikrotik and Mu-Mimo and possibly beamforming in 5Ghz mode. That would last my marriage with Mikrotik last much longer....

One question I asked myself multiple times is why MikroTik doesn't use the drivers from chipset vendors. There are some different opinions about this:
1. Philosophy: MikroTik doesn't want to be depending on the vendor. Keep full control of RouterOS. If this is the management's decision, that's it.
- Technical reasons: Perhaps it is not possible to integrate certain drivers into current RouterOS.
- Licensing costs: I read Qualcomm charges for each mobile device being sold. I don't know if this is also true for routers. But how much more would a cAP ac cost If the Qualcomm driver was used? 99$ instead of 69$?
With 802.11ax MikroTik could start with completely new high performance wireless devices that utilize chipset vendors drivers. Let us customers charge for those better devices. We will happily pay the higher price.

I believe the main reason was the ability to implement protocols like nstream and nv2.

Ok, but when I understand correctly, nstream and nv2 can be phased out once we have 802.11ax ?
Maybe there could be 2 drivers which are selected depending on the protocol mode in use?

I get better results in 802.11ac anyway. If tuned properly it outperforms NV2 and nStreame in almost any circumstance. So maybe they continue to build on the standard drivers and make it even better.
(Although we still would need sync, and for that tdma in any form is needed......)

What would you do if mikrotik does not release a stable tdma protocol or new Access Points. Netmetal is a very old AP. And in the future products shown in the mums they don't have plans for new wireless products.

Mikrotik seems to be focused on routing and the wireless market seems to be not their interest.

I need a very good tdma protocol since even noise floor here is -79.

Bases on your reviews I am trying Mimosa. But in the end I think I will go with Cambium if nothing new from mikrotik next month.

I repeat once again:
- backward compatibility for legacy devices
- asymmetric manual downlink/uplink rate selection
- automatic closed-loop tx-power control
- adjacent channel filtering (like airprism or hypure)
- gps sync for channel reuse

This was the recipe (in given order) for MT to save their wireless. I said that in multiple MUMs, here on forum and via email when communicating with their support. But I guess they know better or simply do not have necessary human resources to do that. Some are only software-based features requiring only programming. Unfortunately it’s too late for them now. I, for example, haven’t bought anything MT wireless for more than a year now and those who have jumped the boat with much financial pain, I doubt ever going back to MT again whatever they introduce. It’s simply a matter of trust and faith now.

And it is time to tell that costumers, but they don't do.....
I can only say, don't buy any new Mikrotik staff because it is one way road....
There is only cheapest crap available, only plastic, no shielding, we have polluted spectrum here,
and Mikrotik hast no spectral scan, this Hardware is unusable!

in 2017 we spend about 25k in Mikrotik, this year something between 2-3k (only switches)
They lost these Market.......

The reasons?
- NV2 delivers about 30% of competitors speed (802.11 is not usable in crowded spectrum)
- NV2 latency is scrap (Mimosa SRS delivers stable 1-2ms, P2P without GPS)
- spectral scan is needed to find working slot
- 802.11ac Hardware perform worse then 802.11n

- 802.11ac Hardware perform worse then 802.11n
Don't agree:

On almost none of my P2MP networks I use NV2. 802.11ac is much better, even in crowded spectrum. We deliver speeds (50 to 100Mbps) to clients where other providers don't. And we still make clients from other wireless providers that in general run the latest UBNT line of products.
We also have 4 Mimosa AP's and although their needed investment is about 3 times that of Mikrotik the extra capacity is only 10-25% at best. And their 48V Ethernet adapters are very vulnerable. Every thunderstorm we lose some. We almost never loose Mikrotik units in the same storms.. (and we do have at least 3 times as much of them....
Last storm we had we lost 6 C5's out of 100 but 0 of 600 Mikrotiks. Now we needed to order new C5's we found they are EOL and we need to buy the new units. ROI for these is 2 years so that is simply not feasible anymore unless the clients pays the whole investment. Some do, other don't and we simply said goodbye to them. Mimosa is a dead end for us....

Spectral scan is needed yes, but in Mimosa its pretty useless as well. It doesn't tell me SSID's nor protocols, only noise. In a crowded spectrum you need a lot more info than only a signal graph that isn't even very 'ergonomic' to work with.
We also have one eCambium EPMS2000 with beamforming. But although their radio works good the price tag is even higher and to run a spectral scan all clients will be dropped. Un usable....

In regard to 802.11ac versus 'n' with Mikrotik. We are hastily upgrading all 'n' networks to 'ac' since we double the capacity of our networks and its much better resilient towards interferences and overlapping AP's. (But in plain 802.11ac mode!)
You guys must be doing something wrong.

example:
We have a coverage by 4 Mimosa A5-AP's that server some 110 clients and one Netmetal serving 40 clients (Mimosa's have 35-40 clients).
They all work in the same housing estate within a circle of only 500 meters.
They all work in 80Mhz wide channel where 2 x 2 Mimosa's are in sync.
Apart from that we have at least 8 sectors from competitors with ubnt pointing towards this estate.
And we have at least some 10 802.11n/ac backhauls leaving/pointing from/towards this estate, 2 of these are airfibres that are run by me.

So, any frequency we use have some overlap with another sector with signal in the range of -60/-80 range.

If we do speedtest from the clients towards our main router we can reach 200-250Mbps on the Mimosa clients under good conditions (not a lot of other traffic) and running on several clients at the same time I saw a couple of times the 300Mbps mark reached.
When we do the same on the Mikrotik clients we can now run 180-220Mbps to clients and aggregated I can push a Netmetal up to 200-230Mbps (35 associated clients!)

If we not take in consideration the easy of the Mikrotik ROS compared to the limited OS for the Mimosa's (all IP level!), the price difference, the vulnerability of the ethernet ports for power spikes and water ingress, and the slow progress of their technology then Mikrotik is again my preferred brand....

Yes Mikrotik could do a lot better. And yes I hope they come up with new radio's.
But we have also several 60HGhz Mikrotik links and 4 sectors and they work splendid with speeds up to the full GB!
We tried Metrolink before but they are all facing the bins now... Never buy them again. Very expensive, poor support, lack of troubleshooting, no follow ups on promised RMS's and the 5Ghz failover is useless. We preferred to have our 'old' Mikrotik 5Ghz backhauls for backup. They at least always worked and with proper BGP failover it works fine when their 60Ghz went down...

You are saing that you can connect more clients with 802.11ac than using NV2?
For some reason when using pure 802.11 I get clients disconnecting, in mu situation.
Maybe the noise floor here is higher.
One clear advantage of using NV2 is that if you have a client who does not have line of sight performance is still regular.
I guess 802.11 does not have that advantage.

Anyway I will consider using pure 802.11AC from mikrotik for small sites and very close clients.

What would you do if mikrotik does not release a stable tdma protocol or new Access Points. Netmetal is a very old AP. And in the future products shown in the mums they don't have plans for new wireless products.

Mikrotik seems to be focused on routing and the wireless market seems to be not their interest.

I need a very good tdma protocol since even noise floor here is -79.

Bases on your reviews I am trying Mimosa. But in the end I think I will go with Cambium if nothing new from mikrotik next month.
And it is time to tell that costumers, but they don't do.....
I can only say, don't buy any new Mikrotik staff because it is one way road....
There is only cheapest crap available, only plastic, no shielding, we have polluted spectrum here,
and Mikrotik hast no spectral scan, this Hardware is unusable!

in 2017 we spend about 25k in Mikrotik, this year something between 2-3k (only switches)
They lost these Market.......

The reasons?
- NV2 delivers about 30% of competitors speed (802.11 is not usable in crowded spectrum)
- NV2 latency is scrap (Mimosa SRS delivers stable 1-2ms, P2P without GPS)
- spectral scan is needed to find working slot
- 802.11ac Hardware perform worse then 802.11n
Don't agree:

On almost none of my P2MP networks I use NV2. 802.11ac is much better, even in crowded spectrum. We deliver speeds (50 to 100Mbps) to clients where other providers don't. And we still make clients from other wireless providers that in general run the latest UBNT line of products.
We also have 4 Mimosa AP's and although their needed investment is about 3 times that of Mikrotik the extra capacity is only 10-25% at best. And their 48V Ethernet adapters are very vulnerable. Every thunderstorm we lose some. We almost never loose Mikrotik units in the same storms.. (and we do have at least 3 times as much of them....
Last storm we had we lost 6 C5's out of 100 but 0 of 600 Mikrotiks. Now we needed to order new C5's we found they are EOL and we need to buy the new units. ROI for these is 2 years so that is simply not feasible anymore unless the clients pays the whole investment. Some do, other don't and we simply said goodbye to them. Mimosa is a dead end for us....

Spectral scan is needed yes, but in Mimosa its pretty useless as well. It doesn't tell me SSID's nor protocols, only noise. In a crowded spectrum you need a lot more info than only a signal graph that isn't even very 'ergonomic' to work with.
We also have one eCambium EPMS2000 with beamforming. But although their radio works good the price tag is even higher and to run a spectral scan all clients will be dropped. Un usable....

In regard to 802.11ac versus 'n' with Mikrotik. We are hastily upgrading all 'n' networks to 'ac' since we double the capacity of our networks and its much better resilient towards interferences and overlapping AP's. (But in plain 802.11ac mode!)
You guys must be doing something wrong.

example:
We have a coverage by 4 Mimosa A5-AP's that server some 110 clients and one Netmetal serving 40 clients (Mimosa's have 35-40 clients).
They all work in the same housing estate within a circle of only 500 meters.
They all work in 80Mhz wide channel where 2 x 2 Mimosa's are in sync.
Apart from that we have at least 8 sectors from competitors with ubnt pointing towards this estate.
And we have at least some 10 802.11n/ac backhauls leaving/pointing from/towards this estate, 2 of these are airfibres that are run by me.

So, any frequency we use have some overlap with another sector with signal in the range of -60/-80 range.

If we do speedtest from the clients towards our main router we can reach 200-250Mbps on the Mimosa clients under good conditions (not a lot of other traffic) and running on several clients at the same time I saw a couple of times the 300Mbps mark reached.
When we do the same on the Mikrotik clients we can now run 180-220Mbps to clients and aggregated I can push a Netmetal up to 200-230Mbps (35 associated clients!)

If we not take in consideration the easy of the Mikrotik ROS compared to the limited OS for the Mimosa's (all IP level!), the price difference, the vulnerability of the ethernet ports for power spikes and water ingress, and the slow progress of their technology then Mikrotik is again my preferred brand....

He cranks up power until all clients are hot enough to stay connected. Nothing which scales but he lives in a hostile environment where every radio cries out loud. If you want to build a sane good performing network you need gps sync, atpc and good antennas.

Quite slow for a 80MHz Channel. With proprietary 5GHz Gear I get near 600MBit capacity on a 50MHz Channel. Hopefully .ax shows better numbers/spectral efficiency.

True. Anything worse than -60 is considered a 'bad' client. But that same counts for our Mimosa's. They are nothing better in MCS rates then Mikrotik.
The only difference I noticed some time ago (over a year) is where two chains have a difference over 3-4db in signal Mikrotik seems to use only one chain (the best one) for data transmission.
I have seen Mimosas that had more than 8dB difference in signal over the two chains but still mcs (and real data transport) represented the use of both chains.
How that actually is done I don't know but that has been one of the advantages I found in Mimosa over Mikrotik 2 years ago when I tested them side by side.

(In fact, the A5 AP needs to be able to do that since it has only one array antenna pointing towards the client where Mikrotik AP's always have two. So it is pretty common for a Mimosa AP to have quite a difference between the two used chains. That is probably also the reason why at bigger distances (over 500meters) Mimosa only uses single chain MCS simply because the 'not facing' antenna strips don't pick up signal (or send) from the client anymore where the MT always has two arrays pointing in the same direction.

The CPU of the Mimosa AP's is much faster then the Netmetal so that is the advantage in P2MP where signals and multi channel receipt is good.
But limit in the Mimosa radio's power is a disadvantage.

If I was on my own, like 10 years ago, yes we could get good results with even -80 or 85 results. Off course, demands were less too.
But now where the competition hits me with signals from remote locations that can hardly be met by my own radio's pointing in the same direction there is not other way than also go for full power and big antennas. -50 at the client is the aim, -45 ideal. -40 superb but stronger becomes questionable. (Although I have worked with signals in the past of -20 (yes, even -10!) it never did 'melt' or break a Mikrotik radio...... they still worked fine......

Mimosa uses the Quantenna chipset which is a BEAST. That said, their deployment model doesn't seem to take advantage of all it's power, and they still don't have a firmware with proper MU-MIMO despite chipset support.

If you are talking any apples to apples scenario though, Mimosa will beat mikrotik and ubiquiti's qualcomm hand's down.


The thing about 'ax is that it takes all the secret sauce out of the mix and basically levels the playing field. Airmax? legacy junk. NV2, NStreme? legacy junk. Custom TDMA implementation on top of 802.11 silicon? legacy junk.

I really expect big things out of Mikrotik and Ignitenet on this front. Two companies that either have a flexible enough platform to just need a drive (Mikrotik) or a business agility to early adopt (Ignitenet).

I should add that I have LTU gear, and I've done some testing on epmp3k. On technical merits, I think gen1 'ax is going to outperform this in even a basic configuration until density gets high enough that GPS sync is needed. At that point, 'ax does have an extension that GPS sync fits so that should be a pretty straight forward development.

I think 'ax is a real game changer and only LTE in licensed bands or CBRS will be a real competitor because if it's superior sensitivity and clean bands.

Rudy,
I tried to reproduce your test using 802.11.
I set an AP with 26 clients connected. I am using mostly SXT Lite 5AC but I have like 6 clients that are either SXT Lite 5 or LHG 5 (N Clients).
I have setup all clients to use RTS/CTS with hardware protection set to 0 (always on).

When I tested a single client (the AP was using like 20Mbps from the other clients) I could get only 12-15Mbps of traffic using a 40Mhz channel.
I then tried using NV2 from the same client, same channel same everything, I could push 60-80Mbps.
It is important to mention that this was an N client.

I tried the same thing with AC client very closed and I could never exceed 25Mbps using 802.11 protocol.

This means, that 802.11AC could deliver very good bandwidth if the spectrum is not so crowded.

Maybe you have very good contion. But we need a better NV2.

Have you enabled adaptive-noise-immunity on wireless interfaces, i.e. set it to "AP and Client mode"?

Indeed, only ~300Mbit/s when connected at 866 Mbit/s. But with Cambium I have similar results. IPQ4019 might not be the best chipset?

For 1.: Yes it´s not perfect.
Cambium E410 (~220$) and MikroTik cAP ac (~70$) use IPQ4019 chipset with 2x2:2.
What chipset is being used on the Ligowave NFT 3ac Lite (~170$)? What about streams? Is it 3x3:3?

True, but one of the advantages of using 80Mhz channel over 40 or 20 even in a 'noisy' 802.11 environment is the ability of the 'ac' standard to skip one of the 20Mhz channels that has to much interference to be usable. The AP will communicate with that client in 2 20Mhz bands only or even one, that give acceptable results.
This way it is possible to work with overlapping 80Mhz channels.

In a P2MP environment where several AP's have to share the same spectrum and where clients have high gain directional antenas pointed towards the AP some of those clients could have interference on channels A+B but another client on C+D or another on B+C. The AP picks then the best set for each specific client and still has a pretty high CCQ on a 40Mhz channel. Other clients that have no interference are still using the full 80Mhz bandwidth so their traffic clears the AP's time superfast so it has more time to deal with the 'slower' clients.

The problem with working in a mixed environment is that although the 'ac' AP is capable to work with both 'ac' as 'n' clients is that it needs too much standard changes which degrades de network pretty fast. I found in such environment it is better to still use 'n-only' then mixed. So my AP's only go to 'ac-only' if all clients are swapped and straight away 'n' clients are no longer allowed to associate.

I work now with ROS v.6.45.5 and still on some tests I'v done plain 802.11ac works much better for the client than NV2. At least 50% more speed towards the client....

Mimosa uses the Quantenna chipset which is a BEAST. That said, their deployment model doesn't seem to take advantage of all it's power, and they still don't have a firmware with proper MU-MIMO despite chipset support.

If you are talking any apples to apples scenario though, Mimosa will beat mikrotik and ubiquiti's qualcomm hand's down.
True. In the beginning I had my first Mimosa A5 AP with 60 (!) associated clients and these clients all where Mikrotik SXT-5ac (mipsbe). I could easily run 180Mbps to these clients, or 2 with some 100Mbps and still had some more traffic from the regular clients. Saw 250-300Mbps traffic aggregated over the AP....
That a wet dream for Mikrotik still...

We then converted the whole area in 4x Mimosa A5 with 120 C5's and 2 x 2 pairs syncd. All in 80Mhz channel. But to be honest, the huge investment didn't really pay itself off. We still have interferences at times, we have some 15% failures of the C5's in 3 years time (which is huge! On my 600 mikrotiks I have less then 1% failures over the last 10 years....) which is a big disappointment in hardware reliability. We also have an ever higher failure rate in the G2's that do the power supply of the antennas. We are facing them our for normal (cheaper!) plain 48V supplies with a cheap Wifi router.
Mimosa had many promises when I started with them 3,5 years ago and several still have to materialize. You think Mikrotik is slow ....?

We are stuck with Mimosa now in this region but I am not expanding its use anywhere else what initially was the idea.
3 years ago the difference between Mikrotik performance and Mimosa was worth the investment, but the new ROS of Mikrotik is good enough for me and we manage to get similar results with Mikrotik as with Mimosa for 1/4 of the price tag. And the client? They don't even notice the difference apart from with every rainstorm we lose another C5......
Now the C5's are EOL I am facing to buy their new line of client devices. And although they might be better in hardware, they are also even more expensive then the C5's.
I made some calculations and see that my ROI (return of investment) for this new line of Mimosa's is 2 years or more... it's hardly worth the effort.....

Happy to see the improvement on cAP AC, seems like they are working hard to bring the best out of it. I'd removed my cAP AC from the listing on some online selling platform, will keep it and see how it performs in ROS v7

i think there is a lot of marketing hype around each new wifi generation, this causes a lot of confusion and excessive expectations

Of course. But for sure every generation was a big step forward. Not as big as announced but big.

Wow, did this thread derail left and right.... :wink:

It seems to me that Mikrotik doesn't announce hardware they haven't started final QC on. Many announcements lately are only a month or two before release it feels like.

I have a grand total of 0 ax-compatible devices. Even if I did have one, the cost to replace all my CAP network would prevent me from jumping to the newly announced ax hardware anyways until I have a strong demand for it. ac is simply good enough for now. I'll let the daring folks beta test for me and rotate out my cAP AC units when I have an honest value in doing so.

I'm suspecting that I'm far from the only one.

I've also heard that, at least in the USA, some more of the spectrum is being considered for release to wifi general use. I'm guessing this will require new chips and/or radios, especially if anything in 6Ghz is offered. So I may just wait and see what happens.

P.S. Anyone else hate that they called it "Wifi 6"? Did we really need to simplify the name?
My Devices: CCR1009 Primary Router+Firewall / CRS328 main switch / 3x cAP AC / BaseBox 2 (RB912) 2.4Ghz AP / NetBox 5 (RB911G) 5Ghz AP / Handful of RB260GS switches.
