Metropolitan Area Networks (MAN)

A metropolitan area network (MAN) is a network with a size greater than LAN but smaller than a WAN. It normally comprises networked interconnections within a city that also offers a connection to the Internet.

The distinguishing features of MAN are

  • Network size generally ranges from 5 to 50 km. It may be as small as a group of buildings in a campus to as large as covering the whole city.
  • Data rates are moderate to high.
  • In general, a MAN is either owned by a user group or by a network provider who sells service to users, rather than a single organization as in LAN.
  • It facilitates sharing of regional resources.
  • They provide uplinks for connecting LANs to WANs and Internet.

Example of MAN

  • Cable TV network
  • Telephone networks providing high-speed DSL lines
  • IEEE 802.16 or WiMAX, that provides high-speed broadband access with Internet connectivity to customer premises.
