Band steering behaivor on Xi-3?

Hi, I have a question on Band steering, does it always steer clients to 5Ghz, regardless?

So, the following scenario, 100 clients with 5 and 2.4Ghz capability, will the Xi-3 try to steer all of them to 5Ghz or will it balance somehow 5 and 2,4 sharing the load on both radios?

    Hello @salva and @Progjes ,

    Thank you for your question.

    Here's how band-steering works today:

    • A dual-band client wants to associate to the ESSID
    • AP detects that it's a dual-band client
    • AP "tries" to push the client towards 5, by making the 5GHz band appearing more lucrative. The way it does this is by tricking the client into believing that the network on 2.4GHz is not "good" . It does this dropping probe responses/authentication responses to be sent to the client only on the 2.4 GHz for the WLAN.
    • Here's where the client behaviour plays a part . The client can either "decide" to connect to 5GHz right away now, or if it's adamant, wait it out until it starts receiving 2.4GHz probe responses again and connect.

    The take-away from this is that:

    • Band-steering happens only during client-association time. Existing dual band clients on 2.4GHz cannot be moved towards 5GHz as they are not "looking".
    • Band-steering is highly dependent on client-driver behaviour. Band-steering is still very successful, but not 100% guaranteed to work always.

    Regarding band-balancing, the XClaim APs today try and push all dual-band clients as long as they meet some criteria. We do not have percentage split at the moment.
