A usual example to understand the concept is cable networks.
Cable TV networks covers a large city as MAN do. But the
difference is MAN is a computer networks whether cable TV
connection connects television.

Technologies used
----------------------

The technologies used to implement MAN are....

1. ATM (Asynchronous Transfer Mode)

2. FDDI

3. SMDS

4. Ethernet based MAN


MAN standard for data communication
-------------------------------------

Distributed Queue Dual Bus (DQDB) is the Metropolitan Area Network standard for data communication. It is specified in the IEEE 802.6 standard.Using DQDB, networks can be up to 30 miles long and operate at speeds of 34 to 155 Mbit/s.
