Device, system and method of scanning a wireless communication frequency band

摘要

Device, system, and method of scanning a wireless communication frequency band. Some embodiments may include scanning a set of channels of a wireless communication frequency band to detect a wireless area network, the scanning including setting a scanning duration to a duration of a beacon interval, scanning a channel of the set of channels for the scanning duration, if a packet is detected over the channel, monitoring the channel for up to a predefined time period, which is longer than the scanning duration, to receive a beacon frame; if no beacon frame is received over the channel, scanning another channel of the set of channels for the scanning duration; and if, after scanning all channels of the set of channels, no beacon frame is received, increasing the scanning duration and repeating the scanning using the increased scanning duration. Other embodiments are described and claimed.
