March 2004 doc. : IEEE 802. 11 -03/11 -04 -0318 -00 -000 jr 0 Handling of MLME-SCAN. request • Parameters of MLME-SCAN request are: MLME-SCAN. request ( BSSType, BSSID, Scan. Type, Probe. Delay, Channel. List, Min. Channel. Time, Max. Channel. Time, Country) Where Channel. List could correspond to different frequency ranges, if applied with different values for dot 11 Channel. Starting. Frequency. • Question: Can the variable dot 11 Channel. Starting. Frequency take a set of values or is it restricted to a single value? i. e. Can a single MLME-SCAN request be issued for channels that have different values for dot 11 Channel. Starting. Frequency? Submission 3 Jennifer Bray (CSR)
