The Gigaset USB Adapter 300
The Gigaset USB Adapter 300 is a WLAN network adapter, which is connected to your PC
via USB (Universal Serial Bus). Gigaset data products make it very easy for you to set up
a local wireless network without having to lay any cables (WLAN = Wireless Local Area
Network).
You can use your Gigaset USB Adapter 300 to connect your PC to a wireless router, e.g.
a Gigaset SE366 WLAN, so that you can access the Internet (infrastructure mode).
You can also connect your PC to other PCs that are equipped with wireless network
adapters (ad-hoc mode).
Since the PCs communicate with each other over radio waves, it does not matter
where they are located, as long as they are within range of the wireless network.
Mobile PCs such as notebooks can link up to the WLAN from various positions without
any difficulty. This enables you to use all the files and printers on the network. The
Gigaset USB Adapter 300 operates in compliance with the IEEE 802.11n transmission
standard (draft, see note below) and is downwards compatible with the previous
IEEE 802.11g and IEEE 802.11b standards. For network security, wireless transmission
can be encrypted using the WPA standard or 64/128-bit WEP.
This user guide instructs you on how to set up a WLAN and gives you important infor-
mation on installation and configuration of your Gigaset USB Adapter 300.
Wireless LAN basics
This section describes some of the basic principles of wireless LANs to show how the
Gigaset USB Adapter 300 functions when you set up a wireless network.
Local Area Network (LAN)
A LAN is a network that exists in a limited area. By a network we mean two or more PCs
that are connected to each other and share files and peripheral devices, e.g. printers.
The Gigaset USB Adapter 300 allows you to communicate with other PCs without having
to lay any network cables. You can therefore also take your PC to another location
without losing the link to the network or the Internet.
Note:
Transmission standard IEEE 802.11n is still pending approval, which is likely to
be granted in the second half of 2008. Your Gigaset USB Adapter 300 is ready to com-
ply with the new transmission standard. You might have to update the software for
your device (page 45).
