This module discussed wireless topologies. First, the components of WLANs
were described, such as mobile devices and client adapters, access points and
bridges, and antennas. A WLAN was defined as an extension to a wired network
environment.
The two major topologies covered were WLANs and wireless
bridges. Some variations, which include the wireless repeater and the workgroup
bridge, were also discussed. Additional features such as fault tolerance, load
balancing, and roaming were also mentioned.
Channel setup was also
discussed along with the importance of planning channel usage, with as little
overlap as possible between channels that use the same frequency.
Finally, some examples of different topologies were covered, concluding with
an overview of Cisco AVVID.
