WSM provides basic query and advanced query. Basic query uses channel as the only criterion for
quick search. Advanced query offers various query criteria for precise match.
Basic query

2. Enter the channel number in the query field on the top right corner.
3. Click the Query icon . The channel list displays evaluation information for the channel
matching the query criterion.
Advanced query

evaluation information for channels whose utilization ratio is less than 20%. This query
criterion has three parts: evaluation index, comparison operator, and value.
The evaluation indexes include:
− Avg. Channel Usage (%)
− Avg. Packet Rx. Channel Usage (%)
− Avg. Packet Tx. Channel Usage (%)
