A Metropolitan Area Network, or MAN , is basically a bigger verson of a LAN and normally uses similar technology. It might cover a group of nearby corporate offices or a city and might be either private or public.
A Metropolitan Area Network often provides efficient connections as it has high-speed transmission capabilities which uses some type of telecommunication components to handle long-distance transmission. One very common example of MAN is the cable television network. Another important Example is the high-speed wireless internet access, which has been standardized as IEEE 802.16
