WiFi 6E MBSSID Beacon Management
The WX Device supports MBSSID (see
WiFi networks (SSIDs) on the WX Device. With the WiFi 6E (802.11ax-extended) standard, the WX Device
divides SSIDs into groups, and includes information of all SSIDs in a group in one SSID beacon. Therefore,
the WX Device doesn't need to send beacons for individual SSIDs, which improves air time efficiency.
Note: If you disable a virtual WiFi network (SSID) whose beacon contains the group SSID
information, WiFi clients of that group will be disconnected until the AP reselects
another SSID to send the beacon.
Out-of-Band Discovery
Out-of-band discovery allows the AP to include information of the 6 GHz band in management frames
sent over the 2.4 GHz /5 GHz bands. WiFi 6E clients only need to scan the lower bands (2.4 GHz/5 GHz) to
connect to the AP in the 6 GHz band, reducing the discovery time.
PSC Channel (In-Band Discovery)
PSCs (Preferred Scanning Channels) are dedicated channels for WiFi 6E clients to send probe requests
on to discover a compatible AP, instead of scanning the entire 6 GHz band. In this way, WiFi 6E clients
are able to efficiently discover and connect to the AP within the 6 GHz band.
Note: The available PSCs differ by country for the unlicensed use in the 6 GHz band.
The following table displays the comparison of the different WiFi standards.
