Roaming
Seamless handover between radio cells, IAPP support, IEEE 802.11d  support
WPA2 fast roaming
Pre- authentication and PMK caching for fast 802.1x authentication
Fast client roaming
With background scanning, mobile access points in client mode can switch to alternative access points which offer a better 
signal before the connection to the first access point fails

Support of up to 4094 VLAN IDs for WLAN connections, 32 simultaneously usable VLAN tags for 802.11x clients
Multi SSID
Simultaneous use of up to 8 independent WLAN networks per WLAN interface
Security
IEEE 802.11i / WPA2 with passphrase or 802.1x and hardware- accelerated AES, closed network, WEP64, WEP128, WEP152, 
access control lists, RADIUS client, user authentication, 802.1x /EAP
RADIUS server
Integrated RADIUS server for MAC address list management
Quality of Service
Support of Wireless Multimedia Extensions (WME, integral to IEEE802.11e), for example for prioritization of voice clients
Bandwidth limitation
Each WLAN client (MAC address) can be assigned maximum transmit and receive rates and an individual VLAN ID
Background scanning
The detection of rogue access points and the channel properties is carried out almost unnoticeably for all WLAN channels during 
normal AP operation.
Client detection
Rogue WLAN client detection based on probe requests
802.1x supplicant
Authentication of an access point in WLAN client mode at another access point via 802.1X (EAP- TLS, EAP- TTLS and PEAP)
Notice
* The effective distance and transmission rate that can be achieved are depending of the given building conditions.
