Hi all,

Having a real tough time with getting my sector to modulate well.  Ive tried multiple channels and still get poor results....

Not sure what to do... Im in an ABAB setup using frequency reuse... 

Thanks!

So why do you think your sector isn't modulating well? Based on the photo you sent, over 50% of your traffic is being sent at the highest modulation level.

Comparing this to some of my e3k AP's, it looks like you're doing pretty well IMHO.

Thank you for your reply!  Maybe my expectations were a bit higher, the uplink is a bit spread out... I have a different thread going in where I stated that I have 16 SMs on this same epmp 3k and my total frame time used is 60% with 52mbps flowing through it... maybe my groupings are no good, I dont know where I should start.   I just looked now and it was at 60% frame time used and only one of my subs was pulling around 36mbps, we offer 20,30 and 40mbps speeds.   Thank you for your help!!
