Roles and the Associations of Wireless Devices
Access Point Role
Access point is the most common role, as it is typically deployed as a LAN device. In the access point
role the router accepts associations from wireless clients and non-root devices, such as a non-root bridge.
If the access point provides its clients a connection to a wired network through a wired connection it is
said to be a
root access point . A device in root mode accepts associations with non-root devices, such as
a non-root bridge.
Figure 1 shows a typical scenario where an access point connects wireless clients to wireless and wired
networks.

Bridge Role
Wireless bridges provide higher data rates and superior throughput for data-intensive and line of sight
applications. High-speed links between the wireless bridges deliver throughput that is many times faster
than the E1/T1 lines for a fraction of the cost. In this way, wireless bridges eliminate the need for
expensive leased lines and fiber-optic cables.
The wireless bridge can link LANs either through the wired interface or through the wireless interface.
Wireless bridges can be configured for point-to-point and point-to-multipoint applications.
