Understanding WDS

The following sections describe WDS and the Cisco wireless mobile interface card (WMIC) can be
configured as a WDS server even when it is configured as an access point. When configured as an access
point, the WMIC can use a WDS server and can act as a WDS authenticator (client).
When you configure an access point to provide WDS, other access points (such as your WMIC, if it is
configured as an access point) on your wireless LAN use the WDS access point to provide fast, secure
roaming for client devices and to participate in radio management.
Fast, secure roaming provides rapid reauthentication when a client device roams from one access point
to another, preventing delays in voice and other time-sensitive applications.
Access points participating in radio management forward information about the radio environment (such
as possible rogue access points and client associations and disassociations) to the WDS access point. The
WDS access point aggregates the information and forwards it to a wireless LAN solution engine (WLSE)
device on your network.
