A mesh network is a type of networking technology that enables devices to connect and communicate directly with each other without relying on a centralized control system. In a mesh network, each device (or node) acts as a relay, passing data to other nodes, which enhances the network's reliability and extends coverage. This decentralized structure is particularly useful in environments with challenging conditions, such as large areas or rural settings, where traditional networks may fail. Mesh networks often improve resilience and can dynamically adapt to changes in the network.
