Building-to-building connection
You can also use local mesh to create point-to-point links over longer distances. in this scenario,
two dual-radio APs create a wireless link between networks in two adjacent buildings. Each AP is
equipped with a directional external antenna attached to radio 1 to provide the wireless link.
Omnidirectional antennas are installed on radio 2 to provide AP capabilities. The two APs are
placed within line of sight.

NOTE: In the above example, all APs must connect to the backbone network via port 1.
Dynamic network
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.
