LAN vs. WAN — What's the Difference?
By Tayyaba Rehman — Updated on September 21, 2023
LAN (Local Area Network) connects devices within a limited area, like a home or office. WAN (Wide Area Network) spans large geographical areas, connecting cities or countries.

Key Differences
LAN, or Local Area Network, is designed to operate over a small physical area such as an office, building, or a campus. On the flip side, WAN, or Wide Area Network, is built to function over vast regions, potentially linking networks across cities, states, or even continents.
In terms of data transfer speeds, LAN generally offers faster speeds compared to WAN. This is because LAN connections are typically used in more localized settings. In contrast, WAN, encompassing larger distances, often has to negotiate multiple networks and traffic, possibly reducing speed.
A significant distinction lies in ownership. LAN infrastructure is usually owned, set up, and maintained by a single organization, ensuring more control over its operations. In contrast, WAN might involve multiple networks, with parts that might be public or leased from carriers.
LAN setups predominantly utilize Ethernet cables or Wi-Fi to connect devices. On the contrary, WAN uses technologies like MPLS, ATM, or frame relay, and may even employ satellite or undersea cable links to interconnect distant locations.
Regarding costs, setting up and maintaining a LAN is generally more cost-effective, given its limited scope. WAN, covering broader areas, can be more expensive, considering the infrastructure, technology, and service fees from providers.
