What does a router do?
Routers connect LANs at different locations and individual PCs to form a Wide
Area Network (WAN). With the appropriate rights, any computer in this WAN
can access the other computers and services of the complete WAN.
A special feature of the router is to send only the data with the connection of
the networks via WAN connection, that should reach the other network. All
other data is held back in its own network.
Connecting a LAN to the Internet does not differ technically from the coupling
of two LANs. The only difference is that not just a handful of computers, but
the ultimate WAN can be found behind the Internet provider's router.
All routers have at least two connections: one for the LAN and at least one for
WAN connections. In addition to the wireless interface for WLAN the models
in the LANCOM 54 Wireless series each also offer an 10/100 Mbps Ethernet
LAN interface, which can be used as DSLoL connector alternatively or simul-
taneously for WAN and LAN connectivity.
The task of a LANCOM 54 Wireless is to transfer data from the local network
to the target network via a suitable WAN connection. Data is also transferred
from the WAN to the desired recipients in the LAN.
