Campus and Metropolitan Area Networks (MANs) Metropolitan area networks (MANs) are network technologies similar in nature to local area networks (LANs), but with the capability to extend the reach of the LAN across whole cities or metropolitan areas, rather than being limited to, say, 100-200 metres of cabling. MANS have evolved because of the desire companies to extend LANs throughout company office buildings of spread across a campus or a number of different locations in a particular city.
