You can use the Gigaset USB Adapter 300 in two different ways. Firstly, you can set up
a direct connection to one or more PCs with wireless network adapters. This is called an
ad-hoc network. Secondly, you can establish a connection to an access point, which
gives you access to an existing wired LAN (infrastructure network).
The
SSID (Service Set Identifier) is the name of a wireless network. It must be identical
for all components of this network.
Ad-hoc network
In an ad-hoc network, PCs communicate with each other via wireless connections. An
ad-hoc network is set up by participants as and when required. All the PCs involved must
have a wireless network adapter installed, e.g. a Gigaset USB Adapter 300 or a Gigaset
PC card 300. Ad-hoc networks are used wherever communications networks have to be
set up quickly and without any existing network infrastructure, and where participants
are on the move.
Infrastructure network
In an infrastructure network, connections are set up between participants over one or
more access points. An access point serves as the basis for the wireless network. It con-
trols connections between the connected participants and can also establish links from
the PCs in a wireless network to a wired LAN (Ethernet) or to the Internet.
Roaming
Several access points can be installed to extend the range of a wireless network. Partic-
ipants in the wireless network can move freely between the various access points with-
out losing contact with the network. As soon as there is a risk of losing contact, the PC
automatically looks for another access point with a stronger signal. All access points and
wireless network adapters must have the same SSID. All access points must be con-
nected to the same Ethernet network.
