Field wireless networks

摘要

Industrial wireless devices and networks are used for measurement and control applications in areas of process plants where it is too difficult or too expensive to hardwire sensors, transmitters, and final control elements. They are also used for temporary applications, such as in research and development and pilot plants. Although most consumer wireless networks are used for convenience, industrial field wireless networks must be much more reliable, and cannot interfere with other wireless applications in the plant. These networks, and their accompanying wireless devices, must also be simple for existing plant personnel to support. Finally, industrial wireless networks and devices must easily integrate with existing wired devices and networks, and the entire wireless system must be flexible and scalable.
