1. high traffic during busy periods: those statistics will be close to 100% and almost all slots will be
utilized. In this case if the Overload statistics show that packets are discarded then this is an
indication of overload condition.
2. high percentage of VCs with low modulation with moderate traffic. Those VCs will require more
slots to service them (due to low modulation) and the frame utilization will be high. In this case the
TDD frame is fully utilized but the system is at low capacity and is not in an overload condition.
450m has higher PPS than 450 and 450i and supports higher throughput through spatial multiplexing,
therefore when a 450m replaces an overloaded 450 or 450i AP the 450m will not be overloaded under
the same conditions but the frame utilization may still show close to 100%; this should not alarm the
customer. The overload statistics shall be monitored on 450m to see if it is overloaded or not.
