A wide area network, also known as a WAN, is a large network of connections that is accessible over a particular area. WANs are used by businesses for reasons including communication, data transmission, and overall better information sharing. But why exactly does YOUR business need a wide area network?
What Is a Wide Area Network?
Wide area networks are a form of intercommunication networks that help your business stay connected both locally and across the globe. WANs are the largest and most efficient series of computer networks that are currently available commercially.
These networks are often established by Internet service providers that then commission their WANs to other businesses. Customers can use the network to relay and store data or communicate with other users, no matter their location. As long as they have access to the established WAN.
What Is the Purpose of a WAN Connection?
WAN connections make it more convenient for businesses to connect across longer distances. This way businesses aren’t restricted to working collaboratively in one geographic area. Many businesses can benefit from having access to resources and communication they otherwise wouldn’t have without a WAN.
As organizations grow and become international, WANs allow them to communicate between branches, share information, and stay connected. When employees travel for work, WANs make it easier to access information during their time away. WANs also help businesses share information with customers and other business collaborators. Everyone involved in your business will benefit from being plugged into a WAN connection.
Difference Between Wide Area Network and Local Area Network
The distinction between a Wide Area Network (WAN) and a Local Area Network lies in their scope and scale. A Local Area Network encompasses a confined geographical area. Such as within a single building or campus, connecting devices like computers, printers, and servers.
Local Area Networks (LANs) offer high data transfer rates and low latency, ideal for supporting tasks within a limited area. In contrast, a Wide Area Network spans larger distances, connecting multiple LANs across cities, countries, or even continents. WANs use router and leased lines to facilitate data transmission over extended areas. But they typically exhibit higher latency due to the larger distances involved.
While LANs excel in local resource sharing and quick communication, WANs are designed to enable seamless connectivity among geographically dispersed locations, supporting tasks that demand broader access and collaboration.
The Different Types of Wide Area Network
There are several different types of WANs, each with its own advantages and disadvantages. Private WANs are owned and operated by a single organization, which gives them more control over the network. However, they can be more expensive to set up and maintain.
Public WANs are shared by multiple organizations, which can save money. However, they may not be as secure as private WANs. Virtual private networks (VPNs) are a type of private WAN that uses the public internet to create a secure connection. This can be a good option for businesses that need to connect remote offices or employees.
Here are some of the most common types of WANs:
Circuit-switched WANs: These WANs use dedicated links between each location, which provides guaranteed bandwidth and reliability. However, they can be expensive, especially for long distances.
Packet-switched WANs: These WANs use shared links between locations, which can be more cost-effective than circuit-switched WANs. However, they may not provide the same level of reliability or bandwidth.
Leased lines: These are dedicated lines that are leased from a telecommunications provider. They offer guaranteed bandwidth and reliability, but they can be expensive.
Metro Ethernet: This is a type of packet-switched WAN that uses Ethernet technology. It is a cost-effective option for connecting locations within a metropolitan area.
Internet Protocol (IP) VPNs: These VPNs use the public internet to create a secure connection between two or more locations. They are a cost-effective option for businesses that need to connect remote offices or employees.
The best type of WAN for your business will depend on your specific needs and requirements. Consider factors such as your budget, your bandwidth requirements, and your security needs when making your decision.
