Beacon Rate, Basic Rate, Data Rate

  • 1.  Beacon Rate, Basic Rate, Data Rate

    Posted Jul 05, 2017 09:04 AM

    Hi,

     

    I know there are a lot of earlier threads regarding this topic, but for me it is not clear yet.

    Especially the difference between beacon rate and basic rate is not clear.

    Can anyone help to make it clear?

    Those are all general terms that are easily searchable on the internet, to be honest, and I would just be sending you a link to those.  Most admins in normal conditions do not change those parameters.

     

    Is there a specific situation where those parameters need to be changed that you would like to ask about?

    We are in a migrate process from a different manufacturer to Aruba.

    It seems that we had some romaing issues in the past with the old system and now we want to avoid those problems with Aruba.

     

    Especially the Motorola MC9200 are effected.

    So, one of the first ideas was to adjust the different rate settings.

    For that we have to understand them in detail.

    That is a valid reason.

     

    Beacon Rate = the rate at which beacons are sent.

     

    Basic Rate = the rate at which management frames to/from the client are sent

     

    Data Rate = the rate at which data to/from the client are sent.

     

    As a practical matter, the power of the access points has a greater impact on roaming than changing the data and basic rates.  Power affects all of the clients on the AP.  You would change the data and basic rates to influence roaming of clients only on a single SSID when you don't want to affect the roaming of clients on other SSIDs.  That would be the strategy. 

     

    Changing from one WLAN manufacturer to the other is tricky because it is typically from older equipment that has less receive sensitivity (ability to hear clients) to better receive sensitivity.  The Aruba antenna pattern (downtilt) means that you could mount an AP with an internal antenna in the place of an external antenna.

    If you need more help, you should hire a professional, because warehouse deployments can be tough...
