Dynamic networks

In this scenario, a controller is deployed with several APs to provide wireless coverage of a

large area. Instead of using a backbone LAN, wireless links are used to interconnect all APs.

AP 1 is the

master

. It provides the connection to the wired network and a wireless link to the

other APs. The other APs automatically established their links to the master based on a

balance between SNR (signal to noise ratio) and hops, to provide the most efficient network

topology.

If a node becomes unavailable, the links dynamically adjust to find the optimum path to the

master.
