As the link between local Ethernet and a wireless network, LANCOM access points inject mobility and flexibility into company networks. The LANCOM L-54g Wireless is
an access point that offers maximum WLAN performance, security and reliability. As well as supporting the 108 Mbps standard IEEE 802.11g, the LANCOM L-54g Wireless
is also compatible to the widespread IEEE 802.11b standard, so offering maximum flexibility in the office or for network coupling. In combination with the LANCOM Public
Spot Option, the access point is also ideally suitable for setting up wireless Internet access services—hotspots—for example in hotels, restaurants, cafés, airports, railway
stations, universities or at trade fairs.
More security.
LANCOM sets the standards in WLAN security. A comprehensive range of security technologies is supported in wireless LAN including IEEE 802.11i, 802.1X, WPA, WPA2,
WEP64/128/152, access control lists or LEPS (LANCOM Enhanced Passphrase Security), which enables the configuration of an optimized solution, whatever the individual
requirements. For example, Multi SSID allows the definition of up to 8 user groups, each with its own level of security.
More management.
LANCOM developments are focused on performance, security and on management, too. LANCOM's WLAN Controllers offer real benefits to network administrators for the
installation, control and monitoring of access points. Settings for wireless, encryption, or access-control lists can be grouped into device configurations, which are then
executed for multiple access points in one easy move. Access points are commissioned and RF optimization carried out automatically. Changes are transmitted to all of
the devices automatically and subsequently monitored. WLANmonitor visualizes the structures of the WLAN irrespective of physical location and facilitates the central
surveillance of the entire wireless network.
More independence.
Equally forward-looking is the support for the Power-over-Ethernet standard. The alternative of supplying electrical power via the network cable enables access points to
be positioned fully independently of the conventional electricity supply and its power points.
What’s more…
To complete the WLAN portfolio, LANCOM also offers suitable AirLancer client adapters and a large selection of high-end antennas for professional indoor and outdoor
applications.
More reliability for the future.
From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back
to older product generations, updates to the LANCOM Operating System—LCOS—are available several times a year, free of charge and offering major features. LANCOM
offers unbeatable protection of your investment!

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.
The effective distances and transmission rates that can be achieved are depending of the site RF conditions*) Note
