What is MAN Network? Advantages and Uses of MAN Network

The MAN network is often misunderstood and confused with other types of networks. If you are looking to learn about urban networks or the MAN network, this article will clarify everything you need to know.

I. What is a MAN Network?

A Metropolitan Area Network (MAN) is a network that spans a large geographical area, such as a big city, town, or any large area with multiple buildings. Essentially, a MAN connects several Local Area Networks (LANs) through cables or other transmission mediums.

The main goal of a MAN is to provide businesses with a variety of services over the same data transmission line, including voice, video, and image. Additionally, deploying applications on a MAN network is simple and fast.

A MAN network is owned by a group of individuals or a network provider that sells services to users, unlike a LAN network. It is smaller than a Wide Area Network (WAN) but larger than a LAN. The maximum distance between two nodes in a MAN network is 100 km.

Structure and Construction of a MAN Network

A MAN consists of several LANs combined together. Additionally, the MAN network can be managed by multiple organizations rather than just one.

Most MAN systems use fiber optics to connect to LANs. Due to its superior advantages in both transmission distance and data transfer speed, fiber optics is the most popular choice. Businesses can use fiber optic connections provided by local Internet Service Providers (ISPs).

Advantages

• Supports bidirectional data transmission simultaneously, with a wide coverage area, typically covering a block of a city or an entire city.

• Installing a MAN allows users to share internet access, enabling multiple users to access high-speed internet.

• MAN can provide high-speed connections over a wide area, ranging up to hundreds of Mb/s and can scale up to 1Gb/s for:

  • E-commerce development

  • Information exchange

  • Government administration management

  • Directing and controlling services

  • Public administrative services

• Higher security compared to LAN networks, with MAN data being relatively safe.

• Maximizes traffic over bandwidth in telecom and IT infrastructure, diversifying services, and enhancing the ability to provide services, resulting in significant profits for service providers.

• Capable of integrating with many networks of different organizations, not just one.

• By integrating new telecom and IT infrastructure on top of existing infrastructure, MAN networks are more flexible when implementing new services.

• Compared to WAN networks, the cost of deploying and building a MAN system is lower because it requires fewer resources.

Limitations

• Compared to LAN networks, setting up a MAN is more costly.

• Building a MAN system requires a significant amount of time and effort and must be performed by skilled technicians.

• Since a MAN consists of multiple LANs, network management is more complex and intricate.

• Bandwidth is generally at an average level.

III. Target Users and Applications of MAN

Businesses and organizations with multiple branches or departments connected together are the primary users of the MAN model.

MAN networks are designed to meet the increasing demand for data exchange between internal and external networks. Today, MAN networks are widely used, for example:

• Connecting to various access networks such as LAN/WLAN, CATV, xDSL, 2G/3G, etc., and with core networks.

• Used in digital cable television broadcasting.

• LAN networks are applied in government agencies, school campuses, airports, hospitals (communication between doctors, laboratories, research), public libraries, etc.

Companies, governments, and individuals all benefit greatly from these projects. Our IT industry has entered a new era with the advent of the MAN system.
