Abstract
Techniques are described for use in scanning by a mobile device which is configured to communicate in compliance with regulatory requirements of a regulatory domain based on country information communicated in one or more beacon frames. The mobile device scans a radio frequency (RF) band using passive scan operations on RF channels having passive scan status, where each passive scan operation involves monitoring an RF channel in attempt to decode a beacon frame. When the mobile device successfully decodes, on an RF channel for a passive scan operation, an information frame of a type that is different from a beacon frame, it changes the passive scan status of the RF channel to an active scan status and performs an active scan operation on the RF channel.
