WAN Characteristics

WANs possess several key characteristics worth noting. Firstly, they cover extensive geographic regions, often spanning entire cities, states, or countries, facilitating long-distance communication. WANs can operate in a public capacity, leveraging the internet for connectivity, or as private networks, like MPLS-based systems, ensuring controlled access and enhanced security. 

These networks offer variable speeds, from traditional T1/E1 lines to high-speed fiber-optic connections, tailored to diverse business needs. Due to their vast geographical reach and diverse technologies, WANs can be complex to manage and configure effectively. It's important to acknowledge that implementing WANs can be a substantial investment, encompassing equipment, dedicated lines, and ongoing maintenance costs.
