WiFi 6E MBSSID Beacon Management
The WX Device supports MBSSID (see Section 1.6 on page 20), which allows you to create multiple virtual
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.
