Item Description
Scan Non-802.11h
Channel
Some of 802.11h channels, also called radar channels, overlap some 802.11a
channels. If the device operates on an overlapping channel, its service quality may be
affected. With this function enabled, the device selects a working channel from
non-802.11h channels belonging to the configured country code to avoid channel
collision.
Selecting the check box before Scan Non-802.11h Channel enables the function of
scanning non-802.11h channels.
By default, the scan mode is auto, that is, all channels of the country code being set are
scanned.
Scan Type
Set the scan type.
Active: The active scanning mode requires a client to send a probe request. This
scanning mode enables a client to discover APs more easily.
Passive: Passive scanning is used by a client when it wants to save battery power.
Typically, VoIP clients adopt the passive scanning mode.
Scan Interval
Set the scan report interval.
A longer scan interval enables a client to have more chances to discover an AP.
A shorter scan interval enables a client to discover an AP more quickly.
