I was looking for this spec, cant seem to find it. which is the PMP450 AP pps capacity?
looking for ways to determine when the AP is reaching capacity limit:
pps?
RF(interference)?
%packet drop?
Currently, the PPS of the AP is around 13,000. This varies a bit with packet size of course.
With R13.4 (check out the beta here), we've added "Frame Utilization" statistics which can help you determine how full the frame is versus whether you're being limited by PPS in any way.
There are also statistics for packet errors, discards, signal levels, etc. which can help complete the picture.
There's a good write up on the Frame Utilization feature and what it does for you here.

Reviving an old thread. So what does an 11% frame utilisation on uplink means. Does that mean the effective switching speed is 11000 times 0.11 now? So 1430 pps?

Frame utilization refers to how much of the RF/Over-the-air resources is used. PPS is a measure of the packet processing capability of the entire system (Ethernet, processor, RF capacity included). There is very little direct correlation between the two. For example, if you are sending only small packets (64 bytes) then you will hit the max processing capability of the CPU before exhausting the RF resources. On the flip side, if you are sending large packets only, the RF resources get exhausted before hitting the CPU processing limit.
A 11% frame utlization means 11% of the air capacity is being used. Frame utlization is typically used to determine if you can or cannot add more subscribers, if you need to improve signal levels of your SMs to achieve a higher modulation (thus less frame utilization) etc.
Hope that helps.
Thanks,
