Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of 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 method comprising: scanning a radio frequency (RF) band using passive scan operations on RF channels having passive scan status, wherein each passive scan operation comprises monitoring an RF channel in attempt to decode a beacon frame; an…
