ETWORK

Using this data, you can determine whether the user’s problem is 
interference due to low bandwidth (Unicast Bytes in). 

3 Select the Trend: Session Stats tab to display Operational Rate, SNR, 

and RSSI statistics.

Signal to Noise Ratio (SNR) statistics can help you determine whether the 
interference is being created by too much noise on a channel. Receive 
Signal Strength (RSSI) statistics can indicate whether a low signal strength 
is creating the user’s performance problem. Operational rate statistics 
display the throughput per second. The following throughput rates are 
optimum: 

„

802.11b–11 Mb/s (optimum) 

„

802.11g/a–36 Mb/s or higher

4 Select the Session Statistics tab to view statistics for the current MAP, 

or for all the MAPs to which the user has connected to the WLAN while 
on the watch list.
