Statistics collected for the RF environment provides data on a per-channel 
basis. You can view noise levels, cyclic redundancy check (CRC) and PHY 
errors, packet retransmissions and percent utilization.
Data collected for the RF neighborhood displays the neighboring radios. 
This information can be viewed as a list of radios heard by a particular 
radio, as well as a list of radios who can hear a particular radio. 
You also can display trending information on a per-radio basis. Trending 
collects radio statistics and charts them on a time basis. For example, you could 
display average throughput rates for the previous 30 days, week, or day. You 
can display and print the charts from 3WXM, as well as generate a report.
Client Monitoring
Client monitoring provides current and historical information about the 
clients using your network, including client activity, watch list clients, 
current client sessions, and the ability to locate clients at your site. 3WXM 
displays the data that WX switches collect on user sessions—either for a 
single user, users associated with a MAP, users associated with a specific 
radio, or users added to a watch list. 
By viewing monitoring information for a user or a group of users, you can 
troubleshoot problems originating from bandwidth constraints or 
roaming patterns. You can collect statistics and view reports on:
„
Client associations, authentication, and authorization failures
„
Client activity, such as roaming and successful authorization
„
Current session status, location history, and statistics
„
Specifics on users over a period of time; information can be gathered 
up to 30 days for session status, location history, client errors, and 
client activity on users you place on the watch list
If you use 3WXM RF Planning, you also can display the approximate 
geographic locations of clients.
