metropolitan area network (MAN) is a large computer network that usually spans a city or a large campus. A MAN Network is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities.
The purpose of MAN (Metropolitan Area Network) is to provide the link to the internet in the long run. MAN Network provides Internet connectivity for LANs in a metropolitan region, and connect them to wider area networks like the Internet. ” It can also be used in cable television.
How Does a Metropolitan Area Network Work?

Metropolitan Area Network is larger than LAN and smaller than WAN. It is generally applied to connect geographically dispersed LANs. Therefore the goal of MAN is to develop a communication link between two independent LAN nodes.
The router is another device for facilitating the network connection. A router helps the data packets to identify the path to be taken. Hence, in other words, it keeps an eye on the data transfer. MAN (Metropolitan Area Network) is usually operated over an area of up to 5 to 50kms.
