Seamless handover between radio cells, IAPP support with optional restriction to an ARF context, IEEE 802.11d supportRoaming
Based on IEEE 802.11r, allows fast roaming procedures between access points. This is possible by using IEEE 802.1X authentication or pre-shared
keys in controller based WLAN installations, which save the access keys temporarily and distribute them to the managed access points.
Fast roaming*
Up to 30 clients (recommended), 512 clients (max.)Concurrent WLAN clients
With background scanning, moving LANCOM 'client mode' access points pre-authenticate to alternative access points which offer a better signal
before Roaming fails
Fast client roaming
VLAN ID definable per interface, WLAN SSID, point-to-point connection and routing context (4094 IDs) IEEE 802.1qVLAN
Dynamic VLAN assignment for target user groups based on MAC addresses, BSSID or SSID by means of external RADIUS server.Dynamic VLAN assignment
Support of layered IEEE 802.1q VLANs (double tagging)Q-in-Q tagging
Simultaneous use of up to 8 independent WLAN networks per WLAN interfaceMulti-SSID
Support for Internet Group Management Protocol (IGMP) in the WLAN bridge for WLAN SSIDs and LAN interfaces for specific switching of multicast
packets (devices with integrated WLAN only). Automated detection of multicast groups. Configurable action for multicast packets without registration.
Configuration of static multicast group members per VLAN ID. Configuration of query simulation for multicast membership per VLAN ID

Prioritization according to Wireless Multimedia Extensions (WME, subset of IEEE 802.11e)Quality of Service
Extension of power saving according to IEEE 802.11e by Unscheduled Automatic Power Save Delivery (equivalent to WMM Power Save). U-APSD
supports the automatic switch of clients to a doze mode. Increasmed battery lifetime for telephone calls over VoWLAN (Voice over WLAN)

If the link of a chosen LAN interface breaks down, a WLAN module can be deactivated to let the associated clients search for a new base stationBroken link detection
Detection of rogue AP's and the channel information for all WLAN channels during normal AP operation. The Background Scan Time Interval defines
the time slots in which an AP or Router searches for a foreign WLAN network in its vicinity. The time interval can be specified in either milliseconds,
seconds, minutes, hours or days
