WAN Engineers (Wide Area Network) are the Telecom/IT professionals that set up and maintain wide area networks for businesses that need these networks to operate regularly. Besides designing WAN networks, they spend much time analyzing, testing and evaluating networks to make sure that they run properly and that they have the resources necessary for smooth functioning.|
Freelance WAN engineers use their expertise in IT to interconnect network systems. They check WAN performance, capacity, security settings, and approvals. Typically, a WAN has at least two LAN’s and covers big geographical areas. Network flow maintenance is important for WAN engineers.
A degree in computer science, information science, or networking is desirable. Some of the mandatory certificates are CCNA (Cisco Certified Network Associate), CompTIA Network+, Juniper, Microsoft Certified Solutions Expert (MCSE), and Wireshark Certified Network Analyst (WCNA).
