802.11a/g Router Applications
A C C E S S I N G T H E I N T E R N E T
The most common use of the 802.11a/g Router is to provide shared Internet access to allow everyone
on your LAN to surf the web and send/receive emails or files. The 802.11a/g Router can automatically
acquire a public IP address when connecting to the Internet. In turn, it will automatically assign IP
addresses to PCs (requesting DHCP client devices) on your LAN - you don’t have to apply for and
assign IP addresses to PCs on your network.

If you want special servers to be accessible to remote users across the Internet (e.g., an e-mail server, an
FTP server, or a web server), you can configure the 802.11a/g Router to
proxy the service using its
(public) IP address. It means a remote user can access the server by using the 802.11a/g Router’s IP
address. Upon receiving a request, the 802.11a/g Router will re-direct the request to the actual server
on your local network.

Additionally, the Wireless Router can also be configured as an Access Point, and acts as the central
point of your local wireless network supporting a data rate of up to 54 Mbps. It allows client devices on
your wireless network to access the Internet, to communicate with other wireless devices on your
wireless network, or to communicate with devices on your wired LAN network.
Since 802.11g is based on the same 2.4GHz radio band as the 802.11b technology, the 802.11a/g
Router can inter-operate with existing 11Mbps 802.11b devices. Therefore you can protect your
existing investment in 802.11b client cards, and migrate to the high-speed 802.11g standard as your
needs grow.
