FIGURE 112 Access Point - Radio RF Statistics screen
The RF Statistics screen lists the following:
Traffic Statistics
Refer to the Traffic Statistics screen to review Access Point radio transmit and receive statistics,
data rate, and packets dropped during both transmit and receive operations.
Radio Displays the name assigned to the radio as its unique identifier. The name displays in the form of a link
that can be selected to launch a detailed screen containing radio throughout data.
Signal Displays the radio’s current power level in - dBm.
SNR Displays the signal to noise ratio of the radio’s associated wireless clients.
Tx Physical Layer Rate Displays the data transmit rate for the radio’s physical layer. The rate is displayed in Mbps.
Rx Physical Layer Rate Displays the data receive rate for the radio’s physical layer. The rate is displayed in Mbps.
Avg Retry Number Displays the average number of retries per packet. A high number indicates possible network or
hardware problems. Assess the error rate in respect to potentially high signal and SNR values to
determine whether the error rate coincides with a noisy signal.
Error Rate Displays the total number of received packets which contained errors for the listed radio.
Traffic Index Displays the traffic utilization index of the radio. This is expressed as an integer value. 0 – 20 indicates
very low utilization, and 60 and above indicate high utilization.
Quality Index Displays an integer that indicates overall RF performance. The RF quality indices are:
•
0 – 50 (poor)
•
50 – 75 (medium)
•
75 – 100 (good)
