Eric, Thanks for bringing this up. We recently started deploying about 30 450 AP's. Our testing in the field and with customers is producing the same EXACT problem you just reported.
More importantly, we see this problem on AP's with low SM's to high SM ranges (5-45). Same firmware. Let's compare some notes: 1. What antennas are you using? 2. What routers / OS are you using? 3. What sync source are you using? We see high frame uses even on the AP's with low SM's and great modulation rates. I can understand if a large number of SM's have low modulation it will eat up frames, but the outcome is the same on low and high SM counts.

I just chaulked it up to issues with the SM since the AP rarely got over 20mb/s downlink. We upgraded to 13.4 recently so we could watch our frame utilization. We started graphing it over night and as you can see, we are hitting 100% for sustained periods of time. During that time the AP is only doing approx. 23mb/s. This particular AP has 34 registered SM and the majority show 6x and 4x with 4 or 5 SM's at 2x and 1x. The performance is a major disappointment. Anyone else have similar experiences? AP configuration: 20mhz channels, 2.5ms frame, 10 miles, 75% downlink, 3 contention slots. Attached is a screenshot of the utilization and sector throughput calculator from the Capacity Planner R13.
