Wide Area Network Pros & Cons

Wide Area Network

When it comes to business, there are many important decisions to make. Deciding a network type is crucial. WAN connects various LANs. It helps businesses to share resources and information quickly and easily. This article discusses the pros and cons of a WAN for your company.

What is a Wide Area Network (WAN)?

WANs are the largest computer networks available. WANs connect LANs across buildings, cities, or countries. Businesses use WANs to share resources and information quickly and easily.

WANs are computer networks leased to businesses, schools, governments, or the public by service providers. The customer’s network communication system needs WAN access.

Different links, such as VPNs or lines, wireless networks, cellular networks, or internet access, can be utilised to gain access. Depending on customer needs, WAN technologies can be used to establish these networks.

Other WANs may use switches to create a circuit-switched connection. WANs are crucial for businesses with various locations, but they’re costly to connect up and maintain. Businesses prefer smaller, more manageable LANs or MANs. WANs are best for connecting employees across great distances.

WAN’s Purpose

Wide Area Network (WAN) is a computer network that spans a vast geographical area. WANs connect LANs and MANs (MANs). Businesses use WANs to share resources and information quickly and easily.

WAN Advantages

  1. Optimize.
  2. Communication.
  3. Wide network.
  4. Share information over a vast area.
  5. QME
  6. It supports worldwide business.
  7. Centralized IT infrastructure.
  8. Privacy and security


WAN can connect sites and allow them to share resources. An organisation with many offices can utilise WAN to connect their office PCs so they can share printers and files. Employees wouldn’t have to walk to separate locations to print documents or access files, increasing productivity.


WAN lets sites communicate easily. With WAN, employees can easily communicate emails, make video conversations, and share data. This would help companies with remote workers.

Wide network

WANs cover wide areas. This helps companies with global employees. With WAN, businesses may easily connect employees in different countries.

Share information over a vast area

WAN can also be used to share information over a broad area. Businesses might utilise WAN to share data with customers or partners in different parts of the world.

Instant Message

WAN lets sites quickly exchange communications. This helps companies communicate with global employees. It supports global business and market. WAN lets businesses connect with global customers and partners.

It supports global business

The WAN enables business anywhere, anytime, with anyone. WANs have no geographical limits. This helps businesses with different locations or telecommuters.

Centralized IT infrastructure

WANs centralise IT for businesses. All of the company’s data and applications are centralised. This helps employees share information and files. It also makes it very easier for IT staff to manage and update the network.

Security and privacy increased

WANs boost enterprises’ security and privacy. Unauthorized users can’t access data stored centrally. WANs can be configured to provide just certain users access to specified information. This gives businesses more data access control.

WAN’s disadvantages

  • Slow
  • complex
  • Costly
  • Public network dependent on third party
  • Security needs
  • Breakdown
  • High-powered gadget needed
  • Installing
  • Slow in Speed

A sluggish WAN is one of the greatest disadvantages of employing one. This is because data must pass through numerous network devices.

Complicated and complex

WANs can be complicated and complex to set up. Businesses must buy and configure routers and switches. Businesses need IT staff to manage the network.


A WAN’s costly cost is one of its biggest disadvantages. Businesses need expensive equipment and monthly expenses. Businesses pay for network installation and upkeep.

Public network is third-party dependent

As a public network, WAN is third-party dependent. This means businesses must rely on their provider to maintain the network working. Businesses must wait for their provider to fix network problems.

Security needs

Since WAN is a public network, businesses need data security. This can increase WAN costs.

Problematic maintenance

WAN maintenance is difficult. It can be very difficult to locate & fix network problems. IT staff and employees can become frustrated.

Need high-powered equipment

Businesses need high-performance devices to maximise WANs. Businesses with several locations may find this costly.

Costs of installation

WAN installation costs are another cost. WANs are expensive to set up, especially with leased lines. The cost of installation can inhibit small businesses that can’t afford it. Costs have dropped out dramatically in recent years, and businesses of all sizes now have reasonable solutions.

Which type of business uses a WAN?

No one answer fits everybody. Depends on business demands. Multi-location or telecommuting businesses may prefer a WAN. Businesses who need to share significant volumes of data or have a centralised IT infrastructure may also find a WAN useful. Consult an IT specialist to evaluate which network is appropriate for your business.

How to set up a Wide Area Network?

Several approaches exist to create a WAN. Most use leased lines. Internet service providers rent leased lines to connect two locations. This more expensive option delivers the highest performance and reliability.

A router connects two LANs to create a WAN. Each router must be configured to communicate with the other router using a routing protocol. Once the routers are configured, the two LANs will be able to communicate and share resources.

WAN troubleshooting and maintenance

  • Ensure a solid network infrastructure.
  • Use recognised networking equipment.
  • Stay up to date on security threats and deploy relevant security measures.
  • Prepare for network outages and other issues.
  • Test your network regularly for problems.


Wide Area Networks have pros and cons. It’s important to examine all of these variables before deciding if a WAN is good for your business.

Multiple-location businesses can benefit from a WAN. By knowing the pros and cons of a WAN, you can decide if it’s ideal for your business. Have you decided if a Wide Area Network is best for you? Comment below.
