Review Step 2c: Characteristics & Trade-offs – Wi-Fi (cont.)

Wi-Fi

One distinct advantage of Wi-Fi is that it combines low per-device cost, no cost for spectrum utilization, modular technologies and hardware, and a mature ecosystem with many vendors. As a result, the topographical network designs of deployments are very large, as they can leverage access points meshed together through point-to-point and point-to-multipoint links. Below are just a few common design for Wi-Fi network deployment that incorporate multiple access points.

Other network typology definitions, such as from the EU, include: Tree (all traffic aggregated upwards in hierarchically); Ring (each node connected to two other nodes) Meshed (each node connected to several nodes for redundancy); and, Star (each node connects to a central node)
