5 Refer to the Errors field to reference retry information as well as data transmissions the target 
Altitude 35xx 802.11a or 802.11 b/g radio either gave up on could not decrypt.
6 Click the Clear Radio Stats button to reset each of the data collection counters to zero in order to 
begin new data collections.
7 Click the Logout button to securely exit the Access Point applet.
Retry Histogram
Refer to the Retry Histogram screen for an overview of the retries transmitted by an access point radio 
and whether those retries contained any data packets. Use this information in combination with the 
error fields within a Radio Stats screen to assess overall radio performance.
To display a Retry Histogram screen for an access point radio:
1 Select Status and Statistics > Radio Stats > Radio1(802.11b/g) Stats > Retry Histogram from the Altitude 
35xx menu tree. 
A Radio Histogram screen is available for each access point radio (regardless of single or dual-radio 
model).
Avg MU Signal Displays the average RF signal strength in dBm for all 
MUs associated with the radio. The number in black 
represents the average signal for the last 30 seconds and 
the number in blue represents the average signal for the 
last hour. If the signal is low, consider mapping the MU to 
a different WLAN, if a better functional grouping of MUs 
can be determined.
Avg MU Noise  Displays the average RF noise for all MUs associated with 
the Altitude 35xx radio. The number in black represents 
MU noise for the last 30 seconds and the number in blue 
represents MU noise for the last hour. If MU noise is 
excessive, consider moving the MU closer to the Altitude 
35xx, or in area with less conflicting network traffic.
Avg MU SNR Displays the average Signal to Noise Ratio (SNR) for all 
MUs associated with the Altitude 35xx radio. The Signal to 
Noise Ratio is an indication of overall RF performance on 
your wireless network. 
Avg Num. of 
Retries 
Displays the average number of retries for all MUs 
associated with the Altitude 35xx 802.11a or 802.11b/g 
radio. The number in black represents retries for the last 
30 seconds and the number in blue represents retries for 
the last hour.
Dropped Packets Displays the percentage of packets the AP gave up on for 
all MUs associated with the Altitude 35xx 802.11a or 
802.11b/g radio. The number in black represents this 
statistic for the last 30 seconds and the number in blue 
represents this statistic for the last hour.
% of Undecryptable 
Pkts
Displays the percentage of undecryptable packets for all 
MUs associated with the 802.11a or 802.11b/g radio. The 
number in black represents packets for the last 30 
seconds and the number in blue represents packets for the 
last hour.
