True... but it's shown Tx/Rx Rate of 320mbps...it is a translation mistake. The pictures clearly show the speed to be 298Mbits. The text which says "speed over 300Mbit" should say "speed of 300mbit"
Nope.. It is completely possible if you have hardware strong enough with 60 MHz channel (30+30MHz) to make 350 Mbit.. The Link speed would be 450Mbit.. Unfortunately the hardware which is made by MikroTik and which can do this is (RB9XX) not supported from MikroTik ROS to do this.. (What a shame)True... but it's shown Tx/Rx Rate of 320mbps...it is a translation mistake. The pictures clearly show the speed to be 298Mbits.

But doesn't matter, theoretical max is 300
Fancy below 300Mbpsit is a translation mistake. The pictures clearly show the speed to be 298Mbits. The text which says "speed over 300Mbit" should say "speed of 300mbit"
This is not true. For 450Mbit link speed you have to have 3 chains. This has nothing to do with power of hardware, but with 802.11n 2x2 standards. Please refer to the 802.11n data rates table here. You will see that with two chains, 300Mbit is maximum: http://en.wikipedia.org/wiki/IEEE_802.1 ... Data_ratesNope..

The mentioned test is UDP. I can clearly say, it can be done by TCP if MikroTik will make driver for special channels as it was by AR92XX chipset family.
On 7XX platform with ROS6 you can do about 270Mbit, but CPU bunches 100pcnt.
Give us some more details about this setupI have 450 with two chains!
What devices do you use on both ends?Just 30 + 30 MHz channel width.
I am concerned about such poor knowledge of MikroTik staff of your own hardware and ROS abilities, but I am not that surprised, because poor knowledge ever was the biggest preacusion of any progress. That is may be the reason and explanation, why you dont support special channels on 9XX (AR93XX family), which is nearly twice CPU powerful as 7XX platform. I can make yu sure. your hardware can do with 2X2 MIMO easy 450link speed within 60MHz channel. If you dont know I can show you easily..This is not true.

Insider, please read my post more carefully. 802.11n standard allows 300Mbit for two chains. This is a fact. You can use custom channels, but it is against the standard. It is possible in RouterOS to use advanced channels (30MHz or other) to achieve this, but this is outside of 802.11n standards. Ropeba shows a good example how to do this, if you don't have to follow standards and regulations.I am concerned about such poor knowledge of MikroTik staff of your own hardware and ROS abilities, but I am not that surprised, because poor knowledge ever was the biggest preacusion of any progress.

You can use Advanced Channels in RouterOS to achive the same setup, but 30+30 is not by 802.11n standard, which I was talking about above.
Only the guy who still speaks about N standard is your self. It is not cas if this is the standard or not. This is the case I am pulling over the MikrTik 350Mbit + on TCP.. But I dont have no AR92XX hardwra which is powerfull enough to do it.. Help us buddy!

You can use RB800 board and use AR92xx mini-pci wireless card and you will be able to get such speeds.But I dont have no AR92XX hardwra which is powerfull enough to do it.. Help us buddy!
Cmon! It is still the same case.. We are making advanced radio relays on your hardware. We chose the 751G platform beacause of Gbit ethernet. The 100CPU is about 230Mbit in 40MHz in standard with 5,2x ROS or 248Mbit with ROS6. If I am using your 60 MHz channel it connect with 450Mbit, but CPU is already "full" on 270 Mbit because it clock is on 400MHz. So if it is not "not strong hardware" if it is misleading, than what is the problem.Your complaint was too vague and mentioned "not strong hardware" which is very misleading. If you are complaining about "advanced channel support" in AR93xx then it is a completely different question.
Look fast as you can - it will be outbreaking news for your platformCurrently RouterOS has Advanced channel support only for AR92xx chipsets cards. It is specified in the documentation:
http://wiki.mikrotik.com/wiki/Manual:Wi ... re_support
AR93xx/AR95xx are newer chipsets and they uses different driver. Currently we haven't made support for Advanced channel feature for those chipsets. We will look if we could add support for them in future.
Pfffff..You can use RB800 board and use AR92xx mini-pci wireless card and you will be able to get such speeds.But I dont have no AR92XX hardwra which is powerfull enough to do it.. Help us buddy!
Maybe this can help you:Dear all.
Can someone explain me, how to setup 60ghz channels on any RBxx with any AR92xx on any ROS???
Write to support@wireless-instruments.com, this is an e-mail to our technicians which have done this test, they will explain you what to do. I don't want to make a mess, they did, so they will explain to anyone interestedDear all.
Can someone explain me, how to setup 60ghz channels on any RBxx with any AR92xx on any ROS???
Can you specify channeling on ISM band ? Or where it is written you have to use some specific channel spacing? 60MHz is nothing else than 3x20MHz. Nstreme and NV2 is not 802.11N either and who cares ?I can do it as described in this link http://www.wireless-instruments.com/en/ ... enna-.html , but what about possible controll of the telecomm agency ? 60 MHz channel isn't the standard of 802.11n ! Won't it bring problems to the WISP ???? What about legality of this solution ?
So... Can you take all range of 5,1-5,9 GHz ? It's k x 20MHzCan you specify channeling on ISM band ? Or where it is written you have to use some specific channel spacing? 60MHz is nothing else than 3x20MHz.

I dont know speciality of your country, but for example in CZ, there is just specification of ETSI norm, channel band and max EIRP power, thats it.. Just do what you can do.So...

The regulations concerns only the EIRP then ?
Mmmmmm?...........What's wrong with PCI bus?Pfffff..You can use RB800 board and use AR92xx mini-pci wireless card and you will be able to get such speeds.But I dont have no AR92XX hardwra which is powerfull enough to do it.. Help us buddy!
mini-PCI? Do you know what is capacity of PCI bus ? This is PCI-E era speed.. let this count your HW staff. Not good idea.
Ok, now count timing of 33MHz bus and 800MHz CPU and memory, look at architecture of PPC. Go ahead You will getsomething bellow 400Mbit buddy.Mmmmmm?...........What's wrong with PCI bus?
PCI 32bit theoritical bandwidth is ~127.2 MB/s.
Let's say that in real world is ~100MB/s - thus 100MB/s x 8 = ~800Mbps and theoritical OVER 1Gbps speed.
800Mbps Bandwidth ISN'T ENOUGH for you?......
Please be carefull of what you write.
Thanks.
It is complete off topic, it belongs to HW section, but everybody from HW dep. of MT know what I am talking about.. Second problem is shared PCI bus, so full thruput I can give only on 2 PCI connectors.Could you be more specific please to understand it?
Thanks.
Of topic but one question.
Are you satisfied with MAX -20dB sidelobs that you have in your site frequency extenders?

I don't know if I could better or not (though I know ), but in my opinion, IF you "start" with a signal "purity" like that, where do you want to go?
So... if there would be a possibility to set 40-50MHz channel, make 2 together in bonding, then we can get much better throughput in MIMO 2x2... isn't it ?I dont know speciality of your country, but for example in CZ, there is just specification of ETSI norm, channel band and max EIRP power, thats it..

It is not matter of channeling 20MHz, but it behaves almost the same, so if you will count correct channel center frequency it will behave same way.. Ok you will not hear beacons of other spots, so it will be more messy, but there is now law break.
Yes, by 40MHz channel and powerfull platform enough it is matter of fact I am doing 248Mbit of NET network thruput. In 60 MHz channel it will be 370Mbit.
So... if there would be a possibility to set 40-50MHz channel, make 2 together in bonding, then we can get much better throughput in MIMO 2x2... isn't it ?
The problem is that as far as I know (but I'm not sure), the maximum channel width is 30 MHz, using channel bonding, we get 60 MHz and that's all we can get in RouterOS. The question is if MT will enable the possibility to operate on 40 MHz channels in the future Anyway, what RB hardware would you use for it ?Yes, by 40MHz channel and powerfull platform enough it is matter of fact I am doing 248Mbit of NET network thruput. In 60 MHz channel it will be 370Mbit.
So... if there would be a possibility to set 40-50MHz channel, make 2 together in bonding, then we can get much better throughput in MIMO 2x2... isn't it ?
currently this board doesn't support Advanced channels feature.Any news regarding this?
AR9300 series (QRT-5) ?
It has enough powerful CPU, gigabit ethernet, 23dBi dualpol antenna and good wlan card.
60Mhz channel width would be 50% more on air rates.
