Wide area networks, or WANs, cover a wider geographical distance than local area networks and allow for a more intricate network. However, they are more expensive and difficult to use than LANs. WANs also have the potential to be slower than LANs.
Unlike a LAN, a WAN connection can span a great distance, such as from city to city or even country to country. For example, WANs are used in technologies such as cell towers and satellites. People at home can set up their own LAN, but a WAN requires a professional installation, resulting in a higher cost to the consumer.
