What hardware requirements for WAN?

The hardware requirements for a Wide Area Network (WAN) typically include routers, switches, and firewalls that support WAN protocols and manage data traffic efficiently. Routers must have sufficient processing power and memory to handle high-speed data transfers and multiple connections. Additionally, WAN links may require specific modems or interfaces, depending on the transmission medium (fiber, satellite, etc.). Lastly, network monitoring tools and possibly load balancers may be necessary to ensure performance and reliability.
