If those 1X and 2X downlink SMs are even moderately active, that really
throws a wrench into the sector performance. This is true on any PMP
platform. We've seen our fair share of it. We've moved a couple back to
FSK which is something I never, ever want to do, but it was
unfortunately necessary.

We have a few 450 AP's with 30-40 subscribers and have been getting
several slow speed complaints lately. 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.
