Industrial Wireless Networks

Industrial wireless networks (IWNs) are a key enabler of many aspects of advanced manufacturing. IWNs promise lower installation costs compared with wired alternatives, increased operational flexibility, improved factory visibility, and enhanced mobility. Wireless networks are not dissimilar to wired networks with the key exception being the transmission medium. Wired networks typically operate over copper wires, coaxial cable, or fiber optic cable depending on the network type. Wireless networks operate without wires or cables using the electromagnetic propagation. As such, wireless networks operate within a shared medium that is publicly accessible. A listing of wireless technologies is listed below:

Home and Office
This includes standards-based communications system typically found in the office environment but may be useful for the factory. Includes IEEE 802.11 variants and Wi-Fi compliant devices. Bluetooth also falls into this category.

Instrumentation
Includes systems specifically designed for factory operation. IEEE 802.15.4 standards such as International Society of Automation (ISA) 100.11a, WirelessHART (IEC 62591:2016), IEC 62601, and ZigBee fall into this category. High-performance standards built on IEEE 802.11 include the Wireless Networks for Industrial Automation - Factory Automation (WIA-FA) IEC 62948. Many exceptional proprietary options exist as well.

Wide Area Sensing
Some applications require the ability to transmit over long distances with minimal power to conserve battery life for sensing and control over wide geographical distances. Examples include LoRaWAN and Sigfox as well as modes of 4G and 5G cellular radio standards.

Other commercial
This category includes systems such as satellite, cellular, directional microwave data links, optical (visible light), and land-mobile radio. This category includes technologies supporting video and voice communication.
