Wireless LAN
Conguring access points at remote sites
It is even possible to manage access points in remote networks with a central controller. The practical
significance of this becomes clear when rolling-out new a WLAN infrastructure. The new access points merely
have to be connected to an external network with IP access. Configuration is carried out centrally via the
controller. This means that WLANs can be rolled-out or upgraded without having trained technicians on site.
Central administration of WLAN routers at home ofces
LANCOM WLAN routers at remote locations, such as home offices, can be centrally managed and monitored
by a LANCOM WLAN controller. The radio module within WLAN routers with VPN can also be configured
and managed from a central controller thanks to LANCOM's "split management". Instead of expert technical
personnel having to travel to remote locations, company security policies are being strictly observed across all
sites.
LANCOM WLAN controllers can automatically configure access points both locally and remotely. The
controller's management software can also detect rogue access points and optionally sends an alert to the
administrator. WLAN routers at remote sites can be securely managed: If the connection to the controller fails,
the local WLAN automatically switches to stand-alone operation.
Smart WLAN controllers provide flexible concepts for a variety of requirements: Performance and operational
reliability. These assets can be maximized by breaking-out the payload from the access point directly into the
network. At the same time WLAN management data is forwarded to the central controller. An SSID that is
dedicated to providing Internet access via WLAN for guests can be securely separated from the network even
where VLAN structures are not in use.
Conguring heterogeneous networks
In most cases WLAN environments rely on a mixture of standards and have clients that need support in various
different WLAN standards in the 2.4 and 5 GHz frequency bands. Frequently employed in these environments
are dual-radio access points such as the LANCOM L-322agn dual Wireless. Each of the two WLAN modules can
be individually configured.
