Figure 1: OpenMesh dashboardMesh networks are a type of wireless network. As you’ll discover, mesh networking is great for blanketing Wi-Fi in larger areas. They are especially useful in places where the environment changes frequently, such as people and walls moving around in malls, trees and buildings growing around an apartment complex, boats moving around the docks, and trucks coming in and out of stops. Additionally, they are perfect for locations and applications where it’s hard to run network cabling.

Instead of having to run Ethernet cables to each of the access points, mesh networks work wirelessly. Only one mesh node (or more for larger networks) must be grounded and plugged into an Internet connection. Other mesh nodes, acting as repeaters, can be placed throughout a building or outdoor area, only requiring power. When someone surfs the web from a repeater, the traffic hops from node-to-node, making it back to a gateway. The hops can vary depending upon the current signal levels among them all. Hence the common saying about mesh, “self-configuring and healing,” and why they are perfect for busy areas…
