Mesh networking is a type of network topology where each device, or node, connects directly to multiple other nodes. This creates a web-like structure that allows data to be transmitted efficiently across the network. If one node fails or experiences issues, the data can still find alternative paths to reach its destination, enhancing reliability and coverage. In a mesh network, devices can communicate with each other without relying on a central router. This decentralized approach is particularly useful in large areas or challenging environments, such as rural locations or buildings with thick walls, where traditional networks may struggle to provide consistent connectivity.
