WLAN Controller

Central Firmware deployment and management of the Access Points. Requires an external web server. Automatic Firmware update on the Access

Points is also possible. The Controller checks every day, depending on the defined policy, for the latest Firmware and compares it with the versions

in the devices. This can also be activated using Cron jobs. If there is a Firmware mismatch, then the Controller downloads the matching Firmware

from the server and updates the corresponding Access Points and Routers.

Firmware deployment

Enables the complete configuration of non-WLAN specific functions such as Redirects, Protocol Filter, ARF etc. Internal storage of up to three script

files (max. 64 kByte) for provisioning access points without a separate HTTP server

Script distribution

The channel deployment can be static or can be automated. Upon activation of the RF Optimization setting, the Access Points search for an optimal

channel in the 2.4 GHz band. The selected channels are sent to the Controller saves these channels on the corresponding Access Points. RF

Optmization can also be activated for individual Access Points. Transmit power setting static between 0 to -20 dB. Alarm notification in case of

Access Point failure by LED, e-mail, SYSLOG and SNMP traps.

RF management and automatic RF

optimization

Definition and grouping of all logical and physical WLAN parameters by means of WLAN configuration profiles. Fully automatic or manual profile

assignment to WLAN Access Points; automatic transfer and configuration verification (policy enforcement).

Configuration management

Support of hierarchical WLAN profile groups. New profiles can be easily created by inheriting parameters from existing profiles.Inheritance of configuration profiles

The AP can be set to 'managed' or 'unmanaged' mode for each radio interface. With LANCOM WLAN routers, the Controller manages the WLAN

part only (split management).

Management operating modes

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.

Stand alone operation

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.

VLAN and IP contexts

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

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.

Redundancy, Controller backup and load

balancing

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).

Fast roaming

802.11e / WME: Automatic VLAN tagging (802.1p) in the Access Points. Mapping to DiffServ attributes in the WLAN Controller if this is deployed

as a layer-3 router

QoS

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.

Background scanning, rogue-AP and

rogue-client detection

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.

WLAN visualization

Static mapping of guest SSIDs in VLANs, access limitations and VLAN routing by means of ARF (Advanced Routing and Forwarding).WLAN guess access accounts

Easy set-up of guest accounts with just a few mouse clicks using the Voucher-Wizard (max. 256 user). The vouchers can be printed over any standard

Printer on the network. The Voucher-Wizard can be customized by uploading an individual logo. Function works without external RADIUS and

Accounting servers. Configuration of time and/or traffic budgets as well as when accounting should start. Support of public certificates and certificate

chains from trust centers for Public Spots. This allows popular browsers to access trustworthy login pages with secure access (HTTPS) without

warnings

Public Spot function

To ensure that load is evenly balanced between multiple Access Points, each one can be set with a maximum number of allowable WLAN clients.WLAN client limiting
