Clean Air Express

Hello)
I have the question and I didnt find good explanation about it((( So I have Cisco 1602 which supports Clean Air Express. Does it change the channel when detect interferrer? Or not? On cisco.com it just says "makes adjustments to optimize coverage"((( Please clarify what does it mean?

When I say 'is done on software", the analysis of the interference is done on software.  Unlike the other models, this stage is done with a dedicated hardware, thereby leaving the APs CPU with more space to do other stuff.  
With CleanAir being done on software, this process is slower in some cases as the CPU has to share resources with other processes.
Go to Wireless > 802.11a > CleanAir and see if CleanAir is enabled globally.

  • AP with Clean-air Express and 3650 controller

    Hi,
    Is Clean-air express supported on the 3650 wireless controller with 1602e APs? The Clean-air options on the controller are available but do not seem to be active. In the controller gui the Clean-air admin status is disabled and the Clean-air operation status is down. I did confirm the Clean Air option is enabled on the config menu for the b/g/n band. Am I missing something here or are these AP's just not supported? Thanks!

    CleanAir Express is different than CleanAir. Express means that the AP does the function of detection, not the controller.  1600's & 1700's run CleanAir Express and you don't have the 100% functionality of CleanAir with these access points.

  • Difference between Clean Air 3.0 and Clean Air Expres

    Hi Community.
    There are some papers which show the difference, but these aren't very clear.
    As i know Clean Air 3.0 will automatically adjust power level, etc. and Clean Air Express doesn't. Is that right, or what should be the main fifference? The CAP1702 (whit Clean Air express) is much cheaper than a CAP2702 (with Clean Air 3.0).
    thanks in advance and kind regards patrick

    It's best to compare the data sheets for each access point, but I would probably lean towards the 2700e, 3600e or 3700e for what you are trying to accomplish. Of course, this will depend upon the size of the organization and budget.

    From an 11n perspective, there are a couple of differences that make the 2700 more suitable for this environment, but that's not to say that the 1600 won't work. The 2700 also supports 11ac.

  • Can i use any wireless printer when using air express

    can i use any wireless printer when using air express

    If you are looking for a new printer, any wireless model will work with the AirPort Express.
    But, since you indicate that you have an iPad, you would want to make sure that the printer you choose is AirPrint compatible. This way, you will be able to print from your iPad....if you need that function.
    See this Apple support document for info on AirPrint and compatible models.

  • Any speed difference between Apple Wifi Router(air express) and Tp link(or others) wifi router)

    Any speed difference between Apple Wifi Router(air express) and Tp link(or others) wifi router?
    I'm using a tp link router and sometimes it takes a long time delay for my 2 mac computers to connect each other. I don't know this is because of the router compability or the computers.

    Anyone knows?

  • Rogue Ap' s and clean air

    Hi 
    Is there a relation between rogue access point detection and clean air , Rogue access point detection is based on the clean air technology  ?

    No, its not.
    Along with what Salodh suggested, following details might help.
    Rogue APs are:
    APs which are not recognised by our controller.
    APs not been created and managed by our controller.
    The controller put those APs in a category called Rogue.
    Disclaimer: Proper Authorization required to attack a Rogue AP. For Example its our building, our floor and a rogue AP shows up in the middle of it, at that point we might have the authorization to disrupt the services of that AP.
    On the other hand,
    CleanAir Technology identifies and resolves RF interference challenges.
    The term Air Quality Index ranges from 1 to 100 (where 100 means that the Radio Frequency doesn't have much interference and 1 means that AP needs to make changes)
    When and AP detects interference, it rates it by Interference Severity Levels (1=Low Interference Severity and 100=Terrible Interference)
    The Interference Severity reduces the AQI levels.
    AQI Sensitivity Levels:
    High sensitivity: If AQI drops below 60, take action to move channels.
    Medium Sensitivity: If AQI drops below 50, take action to move channels.
    Low Sensitivity: If AQI drops below 35, take action to move channels.

  • Migrating to Clean Air

    I have a question that I need answered preferably by a Cisco employee or someone who has migrated to Clean Air.  We are thinking of migrating to the Cisco 3500 series APs in our environment.  I was told a while back that Clean Air is only supported as a fork lift upgrade, meaning all APs would need to be 3500 in order to migrate.  I was also told that we could use the 3500s in monitor mode for troubleshooting, but could not intermingle AP models.
    I am aware that the code level needs to be at 7.0 to have the features of clean air, but is it true that I can not migrate slowly to replace my present APs?  I am in a pretty large wireless environment with multiple WiSMs.  There is just no way to do this all at once. 
    Erick

    So will I still be able to see the benefits of the Clean Air technology in a mixed environment?  Interestingly, that is not the information I was given initially. Are there any features in the 7.0 code that I will not have be able to take advantage of or are there any gotchas I need to be aware?  While the benefits of Clean Air may not be recognized with our b/g clients, will the 3500 APs still service b/g clients for network access?
    I found this straight from the Cisco documentation regarding the Clean Air design guide.
    Mixing CleanAir LMAP and legacy non CleanAir APs in the same installation
    Why should I not mix CleanAir LMAP and Legacy LMAP APs in the same physical area? This question pertains to this use case:
    “I currently have non CleanAir APs deployed (1130,1240, 1250, 1140) in local mode. I want to add just a few CleanAir APs to increase my coverage/density. Why can’t I just add some APs and get all the CleanAir features?”
    This is not recommended because CleanAir LMAPs only monitor the serving channel and all CleanAir features rely on measurement density for quality. This installation would result in indiscriminate coverage of the band. You could well end up with a channel (or several) that has no CleanAir coverage at all. However with the base installation, you would be using all of the channels available. Assuming RRM is in control (recommended) it is entirely possible that all of the CleanAir APs could be assigned to the same channel in a normal installation. You spread them out to try to get the best spatial coverage possible, and that actually increases the odds of this.
    You certainly can deploy a few CleanAir APs in with an existing installation. It is an AP and would function fine from a client and coverage standpoint. CleanAir functionality would be compromised and there is no way to really guarantee what the system would or would not tell you regarding your spectrum. There are far too many options in density and coverage which can be introduced to predict. What would work?
    AQ would be valid for the reporting radio only. This means it is only relevant for the channel that it is serving, and this could change at any time.
    Interference alerts and zone of impact would be valid. However, any location derived would be suspect. Best to leave that out all together and assume closest AP resolution.
    Mitigation strategies would be ill-advised to operate because most of the APs in the deployment would not operate the same way.
    You would be able to use the AP to look at spectrum from Spectrum Connect.
    You would also have the option to temporarily switch to monitor mode at any time in order to perform a full scan of the environment.
    While there are some benefits, it is important to understand the pitfalls and adjust expectations accordingly. It is not recommended, and issues arising from this type of deployment are not supportable based on this deployment model.
    A better option if your budget does not support adding APs that do not serve client traffic (MMAP) is to collect enough CleanAir APs to deploy together in a single area. Any area that can be enclosed on a map area can contain a Greenfield CleanAir deployment with full feature support. The only caveat on this would be location. You still need enough density for location.

  • 5760 WLC Clean Air question

    Hi,
    My customer Cisco 5760 WLCs running as a HA pair. Clean Air has been configured on these boxes but when I do a sh ap dot11 5ghz cleanair summary all the APs show Spectrum Oper State as Down:-
    CPIT-5760-WLC-1#sh ap dot11 5ghz cleanair summary
    AP Name               MAC Address         Slot ID  Spectrum Capable  Spectrum Intelligence   Spectrum Oper State
    AP1                   xxxx.xxxx.xxxx            1  Enabled           Enabled                 Down
    AP2                   xxxx.xxxx.xxxx            1  Enabled           Enabled                 Down
    AP3                   xxxx.xxxx.xxxx            1  Enabled           Enabled                 Down
    Anyone got any ideas as to how I overcome this little obstacle?
    Thanks
    Alan

    Thanks for the reply. As far as I can tell all the radios are operational:-
    and Clean Air has been configured:-
    ap dot11 24ghz cleanair
    ap dot11 5ghz cleanair
    Also the link you sent was for release 7 on the old series controllers whereas this is a HA pair of the 5760s running release 3.03.
    I have been through the configuring Clean Air chapter for this release and it doesn't suggest anything I haven't already tried.

  • Clean Air - WLC 5508

    Hello
    Do I need to buy additional license for clean air to work, currently my BOQ cover
    WLC 5508 with 50 AP license  ( part no : AIR-CT5508-50-K9 )
    20 AP ( model 3502  )
    Redundant Power supply
    LIC-CT5508-50  ( is this required to be mentioned )
    Also I would like to understand are there any better model than AP 3502 & newer WLC model than 5508 ( I would have application users accessing application via Wireless LAN )
    thanks
    ST

    Thank you Scott for the guide will have a look at that.
    5500 series WLC got 8SFP uplinks hence;-
    Can we Group 2 or more SFP for a specific SSID only configured on WLC and other SSID to route traffic from other uplink ports
    Uplinks from WLC to Core are generally configured for failover or link aggregation
    On WLC there are 5 SSID configured for example , the AP installed in HR room should broadcast only ONE SSID ( is this possible )
    thanks

  • Clean air installation

    Why would I deploy all clean air APs that are single radio g/n only. Am I not losing the advantages of 802.11n by not having bonded channels. And if I am concerned enough about interferers to deploy all clean air APs, should I not have 5 GHz available to mitigate the interference?

    The Mavericks on the Air is probably machine specific since it came pre-installed, so it wouldn't work on your computer. See if your friend will let you access the App Store, where you can sign in using your Apple ID and download the installer. You can use this free program to copy the installer and update your computer.

  • Swisscom router und air express

    Muss wegen Umstieg zu Swisscom einen neuen, von Swisscom vorgeschriebenen Router installieren. Laufen die Air Express nur mit Airport Extrem?
    Bitte um eine Lösung, wie ich die Airexpress über den SwisscomRouter laufen lassen kann.
    Besten Dank
    Chris

    Ok, here is the situation...
    I tried both links that you suggested, but to no avail. Everything goes well until I update and then it stops recognizing the AE. I then have to do a hard reboot and reset the AE for the iTunes. I can do the AE for iTunes wireless and the internet wired but not wireless. I do have a WEB security on my router which I believe I entered properly and as far as I know there is no firewall set on my computer. I put security on the AE but still nothing. There obviously seems to be a miscommunication between the AE and the router.
    Any suggestions would be GREATLY appreciated. It is something that would be nice to have, wireless connection for all.
    Thanks,

    You need, a minimum, the AP and the WLC if you want to see how BT is being detected.

  • Clean Air doesn´t work

    Hello All,
    I have 10 Ap´s in a building under a WLC5508 with CleanAir activated, however when the users, turn on a MW oven, the clients located near, lost completely their connections.
    I have activated the EDRRM, but the interference is in all channels, therefore the loss of signal keep it.
    Someone could tell me if this is normal or I have do any adjustment on the config of Clean Air?
    Thanks in advance!

  • Air Express - can it be used outside of iTunes for sound out of Safari?

    I have an Air Express connected to a Wave radio that works great for iTunes music library and internet radio through iTunes. I'd like to be able to play sound through it from web pages while in Safari. Is there any way to broadcast sound through my radio other than through iTunes??

    You can make it happen with the shareware Airfoil.

  • Clean Air in 1552 Mesh Topology

    Hi,
    Is Clean Air supported on MAP and RAP 1552E at a 2,4 Ghz in a mesh toplogy.?????
    at web cisco page: "cleanAir is supported on mesh AP backhaul at a 5-GHz radio of mesh"
    Thanks,

    Yes it is supported on the 1552 on both. The 5ghz though you have to hard set the channels so it will not switch channels
