There is no default limitation on the number of associations supported.
WBSn supports up to 256 associated clients per radio, utilizing the Open
security mode.
Note: For WBSn-2400 v 1.0, up to 127associated clients per radio are
supported.
In other security modes the maximum number of associated clients is different.

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 on the wireless interface using 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)).
