Question 1

In cnMaestro, which metric best indicates the overall health of a PMP 450 sector's throughput performance?

Accepted Answer

Aggregate throughput per sector

Answer

Aggregate throughput per sector directly measures how much data the sector is successfully passing, making it the primary throughput health indicator.

Question 2

What does a rising Receive Power (RSSI) trend in cnMaestro historical graphs typically indicate for a ePMP link?

Accepted Answer

Physical alignment may be improving or an obstruction is clearing

Answer

Rising RSSI on an ePMP link generally means the signal path is improving, often due to better physical alignment or reduced obstruction.

Question 3

Which cnMaestro report type would you use to compare performance across multiple towers over a 30-day period?

Accepted Answer

Network Summary Report

Answer

The Network Summary Report aggregates performance data across multiple sites and supports custom date ranges including 30-day windows.

Question 4

When tracking ePMP 3000 performance, what does a high 'Retry Rate' percentage on the downlink signify?

Accepted Answer

RF channel conditions are degraded, causing frequent retransmissions

Answer

A high retry rate means the receiver is not acknowledging frames on the first transmission, which is a symptom of poor RF channel quality.

Question 5

In Cambium's performance framework, what is the purpose of monitoring 'Airtime Utilization' on a PMP sector?

Accepted Answer

To determine how close the sector is to its capacity ceiling

Answer

Airtime utilization shows the percentage of available transmission time being consumed, directly revealing how close the sector is to full capacity.
