Note: In order to allow QoS through the WBSn-2400, both ends of the network (CPE on the wireless side
and the switch/router on the Ethernet side) should support the same priority tagging. This permits the
marking of a specific packet with a specific priority. WBSn supports DSCP, 802.1p and Auto priority
tagging.
When DSCP is selected, WBSn inspects the incoming IP packets and determines the WMM priority
according to the DSCP priority bits. When W8021p is selected, WBSn inspects the incoming layer-2
packets and determines the WMM priority according to the VLAN-priority bits. When Auto mode is
selected, WBSn checks whether a VLAN tag exists, and if it does, it determines the priority according to
the VLAN priority. Otherwise, the priority is determined by the DSCP value.
Downlink (data sent from the network to the user), a packet from the wire-line network is received by
the WBSn, and its priority detected. The packet will be prioritized over the air according to WMM AC
prioritization. When the packet reaches the CPE, the CPE passes it to its LAN interface according to the
packet definition.
Uplink (data sent from the user to the network), the CPE will detect the priority (as defined at the CPE)
and will pass the frame with the correct WMM AC characteristics, thus providing the priority classification
on the wireless side.

Authentication Combinations
WBSn-2400 allows the following authentication types and combinations.
• The WPA authentication automatically presumes that the basic 802.11 authentication is Open. WPA
defines advanced authentications, either PSK (Pre-Shared Key) or RADIUS. The initial keys are
determined during the last phase of the WPA authentication.
•
[To be supported in future versions.] When RADIUS Authentication is used, the RADIUS server can
determine which VLAN belongs to which user.
Note: WBSn-2400 supports multiple VLAN per VAP.
•
Each VAP can have a different RADIUS server configured. This allows for the transportation of several
networks over the same infrastructure of WBSn-2400
Encryption Methods
Legacy 802.11 clients can either connect using the Open authentication (see above), or WEP. In WEP,
the encryption key can be either 40bit or 104bit. In WPA, WBSn-2400 supports TKIP and AES
encryptions.
Wireless Associations
The Wireless associations list is a list of clients that are connected to the base station. You can access
this list by navigating to Status => Wireless => Associations, where the following list parameters
are displayed.
Parameter Description
IP Address IP address of the associated station
MAC MAC (Media Access Control) address of the associated station
SSID SSID to which the station is associated
RSSI dBm The RSSI (Received Signal Strength Indicator) power received by the WBSn
base station from the associated station.
