A wide-area network (WAN) is the technology that connects your offices, data centers, cloud applications, and cloud storage together. It is called a wide-area network because it spans beyond a single building or large campus to include multiple locations spread across a specific geographic area, or even the world. For example, businesses with many international branch offices use a WAN to connect office networks together. The world’s largest WAN is the internet because it is a collection of many international networks that connect to each other.
Advantages Area Coverage
WAN generally covers geographical areas of large proportions (1000kms or more than that). Probably if your business offices are located at different locations, then without an effort all the branches can be communicated through WAN. For this purpose Internet Service Providers (ISPs) can provide leased lines.
Centralized Data
Using WAN means that you can share the data connected to all the devices in the respective network. For an example you can setup head office server and share the data among all the office branches. Hence, there is no need to purchase separate emails, files and backup servers. Instead you can get all the backup and support from the head office server.
Updated Files
From WAN users can get updated files and data from the servers. Companies can work to update files from the servers so that all the connected devices can receive them. That too in a fraction of seconds.
Message Exchange
With the advancement of Internet of Things (IoT) and LAN, a sudden growth of WAN based devices can be seen. From this communication through messages can be done fast with the help of popular applications such as messenger and whatsapp.
Increased Bandwidth
In order for forming a backbone of a respective network, corporate LAN often often uses leased lines. Using leased lines means that there are more bandwidths compared to a standard broadband connection. Ultimately business improvement in productivity can be seen.
Assured Uptime
Another biggest plus of WAN is that they offer guaranteed uptime. WAN providers offer uptime weekly, quarterly or annually. It is a part of the SLA. It doesn’t matter what the industry is the uptime can be assured.
