ENHANCED PASSIVE SCANNING

摘要

The invention provides an enhanced passive scanning method for a wireless local area network, including the steps of transmitting at least one of a beacon signal (706) or a gratuitous probe response (710) in a WLAN channel by an access point. The gratuitous probe response is a supplemental beacon signal that is transmitted at intervals between the occurrence of regular beacon signals, but contains only essential information to allow mobile station manage roaming and timing.
