The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
For example, a mesh network or MANET with nodes on buildings, towers, trucks, and planes could also be considered a WWAN. A WWAN may also be a low-power, low-bit-rate wireless WAN, , intended to carry small packets of information between things, often in the form of battery operated sensors.

A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances. A WAN uses a communications channel that combines many types of media such as telephone lines, cables, and airwaves.
Common types include local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN). Local area networks have the coverage of a small geographic area, such as a school, residence, building, or company. [4] [5] [6] Metropolitan area networks cover a larger area, such as a city or state. Wide area networks provide ...
An example of a WSAN would be a collection of sensors arranged throughout an agricultural facility to monitor soil moisture levels, report the data back to a computer in the main office for analysis and trend modeling, and maybe turn on automatic watering spigots if the level is too low.
If a network is a local area network (LAN) or wide area network (WAN), every LAN or WAN node that participates on the data link layer must have a network address, typically one for each network interface controller it possesses. Examples are computers, a DSL modem with Ethernet interface and wireless access point.
