Wide Area Network - a long-distance communications network that covers a wide geographic area, such as a state or country. The telephone companies and cellular carriers use WANs to service large regional areas or the entire nation. Large enterprises have their own private WANs to link remote offices, or they use the Internet for connectivity. Of course, the Internet is the world's largest WAN.
