Overview
(802.11i) encryption standard and allow employees to access company resources such as
the intranet.
You can configure up to three VAPs, in addition to the primary WLAN. For information
on configuring VAPs, see Configuring VAPs on page 294.
Wireless Distribution System Links
The UTM-1 appliance enables you to extend the primary WLAN's coverage area, by
creating a Wireless Distribution System (WDS). A WDS is a system of access points that
communicate with each other wirelessly via WDS links, without any need for a wired
backbone. For example, if your business has expanded across two buildings, and a single
access point no longer provides sufficient coverage, you can add another access point that
acts as a repeater. If it is impractical or costly to run wires between the access points, you
can connect them by configuring a WDS that includes both access points.
WDS is usually used together with bridge mode to connect the networks behind the access
points. For example, if you have two network segments, each of which is served by a
different access point, you can bridge the two network segments over WDS links. The
network segments will communicate with each other wirelessly via their access points and
act as a single network. For information on bridge mode, see Using Bridges on page 221.
WDS links are considered a type of VLAN (see Configuring VLANs on page 179).
Therefore, they can have separate security policies, IP network segments, and Traffic
Shaper settings.
