Backhaul
Backhaul is like the behind-the-scenes highway system for telecommunications networks. It's the part that connects local networks (like cell towers or internet service points) back to the main network center. Think of it as the middle part of a three-part chain: local connection to customers, backhaul connection in the middle, and the core network. Just like a delivery service needs roads to connect local warehouses to the main distribution center, telecom companies need backhaul to carry voice calls, internet data, and mobile signals between local areas and their main network. This can be done through different methods like fiber optic cables, microwave transmission, or satellite connections.
