Key Characteristics
A Metropolitan Area Network (MAN) is a network that spans a physical area larger than a LAN but smaller than a WAN, typically covering a city or metropolitan area. MANs connect multiple LANs within a metropolitan region and serve as a high-speed backbone for communication between these networks. They often use technologies such as fiber optic cables, microwave transmission, or wireless technologies.
MANs are typically owned and operated by a single entity such as a government, service provider, or large organization. They provide high-speed connectivity for organizations within the metropolitan area and can serve as an intermediate network between LANs and WANs.
Advantages
- Moderate Geographic Coverage: Covers entire metropolitan areas
- High Speed: High-speed connections between locations
- Cost Effective: More cost-effective than WAN for metropolitan coverage
- Reliability: Reliable connectivity within the metropolitan area
- Scalability: Can accommodate growth within the metropolitan area
- Performance: Better performance than WANs for local connections
- Centralized Services: Enables centralized services for the area
Disadvantages
- Cost: Expensive to implement and maintain
- Complexity: Complex to design and manage
- Infrastructure: Requires significant infrastructure investment
- Coverage Limitation: Limited to metropolitan areas
- Maintenance: Requires ongoing maintenance of distributed infrastructure
- Technology Dependent: Dependent on specific technologies and standards
- Competition: May face competition from other network providers
