Wireless Local Network (Wlan) - Siemens Gigaset SX541 WLAN dsl Manual

Wireless Local Network (WLAN)

In a wireless local network (WLAN), PCs are linked without wires. The PCs have to be
equipped with a wireless network adapter (WLAN adapter) for this purpose, such as a
Gigaset PC Card or a USB Adapter.
We generally differentiate between two types of wireless network.
u
Infrastructure mode
u
Ad-hoc mode
Infrastructure mode
Infrastructure mode connects wireless and wired networks with one another. In addi-
tion to the mobile stations, infrastructure mode needs an access point such as the
Gigaset SX541 WLAN dsl. The stations in the network always communicate via this
access point in infrastructure mode. Each station that wants to be part of the wireless
network must first register with the access point before it can exchange data.
The access point establishes the connection between the mobile stations of a wireless
network and a wired LAN (Ethernet) or the Internet. In this case, this is described as the
device's router functionality. The router sends data packets that are not addressed to sta-
tions within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SX541 WLAN dsl to connect
u
wirelessly networked PCs to the Internet and
u
wirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration of the Gigaset SX541 WLAN dsl. This
configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network set up without an access point or router. The
mobile network components that communicate with each other directly and without
wire connections form the network "ad-hoc", i.e. as and when required. All the stations
in the network have the same rights. Ad-hoc networks are used wherever communica-
tions networks have to be set up quickly and without any existing network infrastructure
and where the participants are on the move.
