What is Metropolitan Area Network

MAN stands for metropolitan area network. As the name suggests a MAN usually have a range of a particular city. They typically use wireless (Wi-Fi or WiMAX) infrastructure or Optical fiber links to interconnect their LAN sites or single computers. In other words it is Local Area Network which is the size of a city.

Technologies that are used to deploy MAN networks in a city or a large area are Asynchronus Transfer Mode (ATM), Fiber Dirtibuted Dtata Interface (FDDI), and Switched Multi Data-megabit Services (SMDS). Metro Etherent is a MAN based on Ethernet which is rapidly replacing the older technologies which are still being used in some areas. MAN can link two LANs which done not by cabbling long distance areas but rathter using wireless alternatives like microwave, radio, or infra-red laser links. Most of the modern companies which deploy MANs for either commercial or private puse, rent or lease circuits from common carriers due to the fact that laying long stretches of cable can be expensive
