Telecommunications Service Providers manage large area networks that can span long distances.  TSPs transports voice and data communications on separate networks. These networks that connect LANs in geographically separated locations are referred to as Wide Area Networks (WANs).

WANs generally connect devices that are separated by a broader geographical area that cannot be served by a LAN.
