Wide-Area Networks (WANs) span a large geographical area and may be public or private. Local Area Networks (LANs) may be deployed within an enterprise, at home, or in public spaces. The WAN/LAN designation indicates the geographical extent of the network but doesn’t specify network implementation technology.
The public internet is a WAN that most enterprises use to connect to RingCentral unified communication services. Enterprises can also use RingCentral Direct Connect on private Wide-Area Networks to connect an enterprise site or a data center to the RingCentral cloud (Section 3.4
You have a number of options for implementing WANs, including internet, Ethernet Virtual Private Line, MPLS, 4G/5G mobile networks, SDN, and SD-WAN. In principle, each of these technologies can be used to connect to the RingCentral cloud.
Enterprise Local Area Networks have largely standardized on Ethernet and WiFi network technologies.
