1-1 Introduction
The WLAN 802.11a/b/g device allows you to access Wireless Local Area Networks (WLANs),
share a local printer and files with others in your network, access the Internet, and roam about the
office—wirelessly. This wireless Local Area Network solution is designed for both large and small
businesses, and it is scalable so that you can add users and new network features as your
networking needs grow.
The WLAN 802.11a/b/g device is a dual band WLAN device that allows for access to both
2.4Ghz and 5Ghz WLAN technologies. The WLAN 802.11a/b/g device will operate with at a
maximum data rate of 11Mbps with 802.11b (2.4Ghz), 54Mbps with 802.11g (2.4Ghz) wireless
networks and a maximum data rate of 54Mbps with 802.11a (5Ghz) wireless networks. The
WLAN 802.11a/b/g device will automatically detect and seamlessly roam between both 802.11b
(2.4Ghz), 802.11g (2.4Ghz) and 802.11a (5Ghz) wireless networks
1-2 Using a Wireless Local Area Network
A wireless LAN provides the same functionality of a wired network, but it eliminates the need to
install networking cables and other networking equipment. Not only is a wireless LAN easier to
deploy, but it also allows for mobility through “roaming.” For example the WLAN 802.11a/b/g
device can roam from a conference room to an office without being disconnected from the network.
