In the realm of networking, a Wide Area Network (WAN) connects geographically dispersed local area networks (LANs). While routers form the backbone of this connectivity, they often require specialized hardware to physically interface with various WAN services. This is the primary function of a WAN module. A WAN module is a removable interface card that plugs into a slot on a router or a network switch, providing the necessary physical ports and processing power to connect to external networks. Instead of being built-in, this modular approach offers significant flexibility, allowing network administrators to customize their equipment based on specific needs without replacing the entire router chassis.
