Best Practice Installation Settings for AirMax

[UBNT-Mike.Ford]

Hey Guys,

Here are the slides from the conference:

Thanks,

Hi Mike, are these based on the current v5.1 release or an upcoming revision?

[jcrites2008]

Hmm I can't get the link to work.

Nice little slide show. Is there any benefits other than mac preservation in utilizing ap/wds, sta/wds mode as compared to just regular ap, sta mode?

[popcorrin]

Hmm I can't get the link to work.

just copy and paste the link into your address bar

[jcrites2008]

Still not working...

Hmm I got it now, I had to type it in manually with a space between "Best" and "Practices".

Yeah I am curious about the WDS thing as well. I see it being said around but I have as a rule of them never employed WDS as a network cause it just doesn't fit in out network.

But from what I have been reading utilizing WDS on the Ubiquiti stuff isn't necessarily for the original use or layout of WDS.

So the question remains, If we aren't using WDS as its originally intended to provide bandwidth from one AP to another with out a PTP setup but more meshy why would we use WDS on the station and AP?

Whats its use? I have seen the MAC thing listed but no real indepth explanation.

Why 20Mhz or less on PTMP? So it propagates better aka PSD (power spectral Density)

[UBNT-Mike.Ford]

Guys,

In all of my slides, I use AP/WDS to STA/WDS for MAC preservation, routing preservation ect.

Also,

I recommend 20Mhz for PTMP as its more likely to get interference in a 40Mhz channel.

Remember these are only suggestions, your needs may differ.

Thanks,

Mike

What's the maximum throughput on the AirMax kit when using 20MHz channel width compared to 40MHz?

100Mbps TCP/IP aggregate.

i need the correct programation for a M5 NANO system for use with a domo camera and my question: is needed a full señal for the correct funcion?
i ve two leds of señal and no response
sorry for my bad english. tks

oi fence dweller,

go buy some radios!

:)

Need that grant brass first. :thumbsup:

And some people to say yes...

@mike

thank you

Hi,
Each network has its peculiarities and not all may apply certain settings that have failed in other networks. Our network is located in the city and as you know some problems occur in cities such as spectrum is loaded, not all of los and others. However we are pleased with the speed (60-70 Mbps to the customer) for 1-60 ms, connection very stable no matter the weather.
Settings you use:
-firmwere 5.1.2
-Channel Width: 40 MHz
WDS-Wireless Mode
-Max TX Rate, Mbps: Auto
-Enable AirMax: off
-No ACK Mode for PtP: off
-ACK Timeout: off
-Aggregation: enable
-Multicast Data: off
-Enable Extra Reporting: off
-Enable DFS: off
-Enable Client Isolation: on
-Enable Autonegotiation: on

I am happy when clients are satisfied.
Thank you all for advice.

hi,

i am trying to find the no-ack option on the station side in AirOS 5.1.2 as described in the pdf, i can't find it.

i am having a PtP link on a distance of 30km which according the the gui will not work with 40MHz channel width. the max setting for ack timeout is 26.6 km.

thanks

Maybe you could add a section or guideline as to proper spacing of the Ubiquity M Series radios. How far apart do they need to be physically so as to not self-interfere with each other?

no ack is set with airmax on the master. the station self-sets to no ack when it finds its master

sangat setuju ...... saya sudah memakainya untuk 35 km link dengan channel width 40 mhz

why use in ptmp Ap-wds why just Ap

and the second side on Station no Sation-wds

[xunii]

in this slide AirMax is On ..
while it is experiences that when we on AirMax the ping response is not and ms times goes high .. but when we turn off AirMax the ping response shows normal ..
why it is happened ???

Hello,
I have installed 120 degree sector antenna with M2 Rocket. Airmax is on, alowed frequency range in my country is 2412-2497, noise floor -91, CCQ-90. The average number of custommers is 29.
Now, problem descriprion: Very often, sometimes 3-4 times a day, costommers are complaining about low performance-they can not get enough MBs. Checking this, I find out that ping delay from M2 to any custommer antenna goes up to too a high level (sometimes more than 200ms). I change the frequency, for exaplme from 2422 to 2472, or to other digit untill the problem is solved.
I think that noise floor is the problem source, as site survey tool shows about 4-5 working antennas of other companies. Is there any mean to make work of my antenna stable?

Only way to solve this is to avoid the interference. Drop channel width down if you haven't already to see if that improves overall performance throughout the day. -91 noise is awesome on 2.4 to be honest. What are the problematic CPE's seeing as far as signal/noise?

There are airgrid M2 HP antennas at custommer sides. When the problem emerges, all of them experience it. The noise floor is 89-90, signal strength differes from 45 to 78. I'va dropped channel width to 20.

Wonderful attempt altogether and great discussion, as I am new to this so do not know much about it. But soon will learn and add value to this. Thanks for sharing it.
