The term "wide area" refers to a geographically large region or space. In computer networking, wide area networks (WANs) are used to connect multiple local area networks (LANs) that are separated by long distances such as cities, states or even countries. Wide areas can also refer to the coverage of services and systems that span across a broad geographic location, for example, wireless communication services that provide coverage over large metropolitan areas or entire nations. In summary, "wide area" refers to something that covers a significant expanse or territory.
