By understanding the key differences between WANs and WWANs, organizations can make informed decisions about which technology to use for their specific needs.
What Is A Wide Area Network (WAN)?
A Wide Area Network (WAN) is a type of network that connects devices and locations over a large geographical area, such as cities, states, or countries. It is typically used to connect multiple local area networks (LANs) or metropolitan area networks (MANs) together, allowing them to communicate with each other and share resources.
WANs can be used for a variety of purposes, including connecting remote offices, providing internet access, and supporting telecommuting. They can be implemented using a variety of technologies, including leased lines, Frame Relay, ATM, and MPLS. WANs can be either private, meaning they are owned and operated by a single organization, or public, meaning they are provided by a third-party company.
What Is A Wireless Wide Area Network (WWAN)?
A Wireless Wide Area Network (WWAN) is a type of network that connects devices over a large geographical area, similar to a WAN, but uses wireless communication technologies. WWANs use cellular networks, such as 2G, 3G, 4G, or 5G, to provide connectivity between devices. They are often used to provide internet access, communicate with remote devices, and support mobile devices.
WWANs are commonly used by mobile network operators to provide mobile phone and internet services. They are also used by organizations to provide connectivity for remote workers, vehicles, and IoT devices. WWANs can be implemented using a variety of technologies, including cellular networks, satellite communications, and wireless broadband.
What Are The Key Differences Between WAN And WWAN?
The key differences between WAN and WWAN are the type of technology used, the geographical coverage, and the mobility support. WANs typically use wired technologies, such as fiber optics or copper cables, while WWANs use wireless technologies, such as cellular networks or satellite communications.
