Up to 26 non- overlapping channels (available channels and further obligations such as automatic DFS dynamic channel 
selection depending on national regulation)

Roaming

Seamless handover between radio cells, IAPP support with optional restriction to an ARF context, IEEE 802.11d  support

WPA2 fast roaming

Pre- authentication and PMK caching for fast roaming

Fast client roaming

With background scanning, moving LANCOM 'client mode' access points pre- authenticate to alternative access points which 
offer a better signal before Roaming fails

VLAN

VLAN ID definable per interface, WLAN SSID, point- to- point connection and routing context (4094 IDs) IEEE 802.1q

Dynamic VLAN assignment

Dynamic VLAN assignment for target user groups based on MAC addresses, BSSID or SSID by means of external RADIUS server.

Q- in- Q tagging

Support of layered 802.1q VLANs (double tagging)

Multi- SSID

Simultaneous use of up to 8 independent WLAN networks per WLAN interface

IGMP snooping

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

Security

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

RADIUS server

Integrated RADIUS server for MAC address list management

EAP server

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

Quality of Service

Prioritization according to Wireless Multimedia Extensions (WME, subset of IEEE 802.11e)

U- APSD/WMM Power Save

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)

Bandwidth limitation

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

Broken link detection

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 station

Background scanning

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

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)

Layer- 3 Tunneling

Layer- 3 Tunneling in conformity with the CAPWAP standard allows the bridging of WLANs per SSID to a separate IP subnet. 
Layer- 2 packets are encapsulated in Layer- 3 tunnels and transported to a LANCOM WLAN controller. By doing this the access 
point is independent of the present infrastructure of the network. Possible applications are roaming without changing the IP 
address and compounding SSIDs without using VLANs.
