Scope of features: as of LCOS version 7.8x
Stand alone operation
In 'Managed' mode, an adjustable setting defines the time- span for which the AP continues Stand- alone operation in the event
the connection to the Controller fails. After this time- span the AP configuration is deleted and the AP resumes operation only
after the connection to the Controller is reestablished. By default this value is set to zero and AP ceases operation as soon as
connection to the Controller is lost. Alternatively, a special time setting allows the AP to function in Stand- alone mode
indefinetly. In Stand- alone mode only Pre- shared Key SSID's are functional.

VLAN and IP contexts
A fixed VLAN can be set for each SSID. The WLAN Controller can independently provide up to 16 separate IP networks, and each
of these can be individually mapped to VLANs and, consequently, to SSIDs (Advanced Routing and Forwarding, ARF). The
Controller can provide, among others, individual DHCP, DNS, routing, firewall and VPN functions for these networks.

Dynamic VLAN assignment
Dynamic VLAN assignment for target user groups based on MAC addresses, BSSID or SSID by means of external RADIUS server.
RADIUS server
Integrated RADIUS server for MAC address list management. Support for RADSEC (Secure RADIUS) for secure communication
with RADIUS servers.
with RADIUS servers.
EAP server
Integrated EAP server for authentication of 802.1x clients via EAP- TLS, EAP- TTLS, PEAP, MSCHAP or MSCHAPv2
RADIUS/EAP proxy
Proxy mode for external RADIUS/EAP servers (forwarding and realm handling)
Redundancy, Controller backup and
load balancing
load balancing
Every managed LANCOM AP can be assigned to a group of alternative WLAN Controllers. A suitable Controller is selected within
this group depending on AP load. This ensures that also in backup state the load of larger installations remains equally
distributed.

Fast roaming
VoWLAN devices require seamless roaming for ensuring optimal speech quality. The Access Points support PMK caching and
Pre- authentication for such demanding applications. WPA2 and WPA2- PSK operate with sub- 85 ms roaming times
(requirements: adequate signal quality, sufficient RF overlap, clients with a low roaming threshold).

Background scanning, rogue- AP and
rogue- client detection
rogue- client detection
Background scanning does not interupt normal AP operation and collects information on the radio channel load (AP acts as a
'Probe' or 'Sensor' by going off- channel). Foreign Access Points and clients is sent to the Rogue AP Detection in LANCOM
WLANmonitor.

WLAN visualization
The management tool LANCOM WLANmonitor (included) acts as a central monitoring program for the WLAN Controller and
visualizes the performance of all WLAN Controllers, Access Points, SSIDs and clients.
