Channel Bonding Symbols (+, -, S)

    Posted Jan 04, 2023 10:55 AM
    Hello All,

    Please correct me if I'm wrong, but in Mobility Conductor, when it says "Channel 40-" it means it's bonded with a lower channel. Similarly, 108+ would mean it's bonded with a higher channel.

    But when it comes to 6GHz channels, I'm now seeing a new symbol "S". What does the S represent? (For example, Channel 37S or Channel 149S). Is this more to just represent it's a 6GHz channel? 

    Thanks,
    Nate

    This help? :

    +/- = 40 MHz
    E = 80 MHz
    S = 160 MHz
    E+E = 80 + 80 MHz (i.e. 36E+149E)

    Hello Dustin,

    Thanks for the reply, that's exactly what I was looking for, thanks! The primary reason I was asking was that I see we have channels 37S and 149S on two APs. Why are these channels the primary channels listed? Instead of channel 47S and 143S (6E). What is the significance of the listed channel in MM? 

    Thanks,
    Nate

    Thank you so much! I stucked in why only 20Mhz worked, and change to 40Mhz when I enabled 36+ ....

    Is the S representing the Preferred Scanning Channel (PSC)?

    No. S means that you are bonding 8 channels together into one 160Mhz wide channel. I would highly recommend turning off 160Mhz, and even 80Mhz wide bands to reduce your CCI. I always recommend using 20Mhz wide for 5Ghz radios, and bump up to 40Mhz if you need more throughput. Be aware though that when you bond channels, it gives you less to pick from when laying out your channel coverage. You want to try and avoid overlapping coverage of APs using the same channel.

    This is for 6Ghz channels. We are just doing testing in our environment right now (will likely run 80hz for 6Ghz in production).

    Yes that makes sense :)

    You can see the flags used and a description, when you use the command
    show ap active

    see the description of the flags in the example output - Channel Flags
