Metropolitan area networks, usually abbreviated MAN, are networks that span a metropolitan area that consist of two or more networked computers. These networks can be private or public. They can be used to network two or more LANs together. Large university campuses may have these types of networks, particularly if they have several satellite locations.
Metropolitan networks are not cellular networks, as those types of network carry standardized information packets. To fall under 802 standards, a network has to allow different sizes of information packets to be sent across the network. Therefore, a mobile cellular connection to a LAN does not create network that would be considered a MAN, but a computer that is located far away from the parent LAN but uses technology that allows different sizes of information packets to be sent would be considered to be part of a MAN network.
