The Difference Between LAN, MAN, and WAN is Private

A LAN is a group of devices that are interconnected to allow for communication. A defining characteristic of a LAN is that it’s privately owned. The network devices are generally owned by the same organization using the network. For that reason, LANs typically cover one narrow geographical area: a coffee shop, hospital or college.

A MAN covers a larger area than a LAN but it remains a defined geographical region. Compared to a LAN, a MAN comes with all the drawbacks you’d expect from a larger network, more congestion and lower transmission speed. But the critical difference is that many of the components of a MAN are publicly owned — or at least not owned entirely by the networks operating on them.

A WAN is different from a LAN or MAN in that it’s generally not defined geographically — it’s a huge interconnection of devices and networks, from a number of different places. WANs are almost never privately owned and depend on public infrastructure and systems to maintain connection.
