WAN Technicians are experts who resolve problems relating to an
organization’s wide area network (WAN), whether it be onsite or in the
field. They further evaluate existing network systems. Technicians also
supervise the maintenance, installation, and operation of a wide area
network as well as related computer hardware and software.

Technicians must ensure network connectivity in all sizes of buildings.
Technicians further perform the installation of a wide area network’s
hardware and software, for the purpose of creating enterprise-wide data
communication through the means of an intranet.

Technicians or
freelance telecom professionals often work in conjunction with
telecommunication companies to make certain that WAN services meet
organizational requirements, and they also make sure that service
providers can support their organization across all its locations.
