A Local Area Network (LAN) is not a strategy for deploying a Wide Area Network (WAN). WAN deployment strategies include using the public Internet, private enterprise WANs, or carrier-managed WANs. LANs, by definition, serve local, not wide-area, connectivity. ISA/IEC 62443 standards refer to different strategies for extending network communications over broader geographic regions, but do not classify LAN as a WAN deployment option.
