QoS (Quality of Service) Packet Priority
Wireless Multimedia Extensions (WME), also known as Wi-Fi MultiMedia (WMM), provide basic QoS features
to IEEE 802.11n networks. WMM prioritizes traffic according to four Access Categories (AC):
• Voice
• Video
• Best Effort
• Background
Traffic is prioritized by these access categories, and the implementation defined by the WMM standard.
Traffic is therefore suitable for applications that require QoS over Wi-Fi, (for example, Voice over IP (VoIP)).
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 priority tagging. This permits the marking of a
specific packet with a specific priority.
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.
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.
TX Rate PHY Rate (modulation) at which the base station currently transmits to the
associated station
RX Rate PHY Rate (modulation) at which the associated station currently transmits to
the base station
State Indicates the status of the station’s connection:
• Connecting
• Associating
• Requesting Authentication
• Connected
Est. Range Estimated range of client from WBSn
WMM A value of 'yes' in this field indicates that the associated station supports the
WMM protocol
Auth. Status Authorization status
Radio 2.4 GHz or 5.0 GHz
PS Power Save status
11N Indicates whether the CPE supports 802.11n protocol
