Roaming

Opportunistic key caching allows fast roaming processes between access points. WLAN installations utilizing a WLAN controller and IEEE 802.1X
authentication cache the access keys of the clients and are transmitted by the WLAN controller to all mananged access points

Opportunistic Key Caching***

Pre-authentication, PMK caching, and opportunistic key caching for fast roaming

WPA2 fast roaming

Up to 30 clients per radio (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 802.1q

VLAN

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 interface

Multi-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

IGMP snooping

IEEE 802.11i / WPA2 with passphrase (WPA2-Personal) or IEEE 802.1X (WPA2-Enterprise) and hardware-accelerated AES, closed network, WEP64,
WEP128, WEP152, user authentication, IEEE 802.1x /EAP, LEPS, WPA1/TKIP

RADIUS server

Integrated EAP server for authentication of IEEE 802.1X clients via EAP-TLS, EAP-TTLS, PEAP, MSCHAP or MSCHAPv2

EAP server

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)

U-APSD/WMM Power Save

Maximum transmit and receive rates and an individual VLAN ID can be assigned to each WLAN client (MAC address)
