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.
