One of the easiest ways to determine which type of network you need is to explore your business set up. A small office or business will typically only need a LAN. The local network will ensure that different files can be transferred through your office leading to a connected business environment. If you have a larger business or multiple branches, that’s when you’re going to need a WAN. This means that you will be able to connect to those branches or different business offices on a unified system. So, while LANs are used for homes, businesses, and schools, WANs provide more widespread connections. LANs will also usually be privately owned whereas WANs will often be run by a third party like a telecom provider. They can also operate on a public network.
Speeds. Generally, it will be easier to boost speed levels and reach higher speeds in a LAN network compared to a WAN. This will depend on the hardware and cables used but because you can connect devices physically, it can be incredibly rapid. LAN devices can also be connected to the same router or switch which again does mean faster connections.
In contrast, WAN speeds can be impacted by various issues. You need to think about the equipment you are using but it will also depend on the equipment used in the network itself. You won’t typically have any control over this and WANs will be slower due to the distance data will have to travel. Technology is changing all the time and high-quality copper cables are used to speed up WAN connections.
