A mesh network connects multiple devices, or nodes, so they can pass data directly or relay it through other nodes. Unlike a hub-and-spoke network that depends on a central point, a mesh can provide several possible routes between endpoints. Some networks use a full mesh, where every node connects to every other node; others use a partial mesh, with links between selected nodes. Routing can adapt as connections change, allowing traffic to take another path when a link is unavailable. Mesh designs are used in both wired and wireless networks, including systems where devices need to communicate across an area without depending on one central access point. Their coverage and resilience depend on the number and placement of nodes, the strength of their links, and how the network manages traffic.
