17.2 WirelessHART Radio Communication Standard
An exciting development in industrial instrumentation is the WirelessHART radio communication standard, specifically designed for field instrument use (e.g. transmitters, valve positioners) as opposed to general data communication. The IEC (International Electrotechnical Commission) has codified the WirelessHART standard as IEC 62591. 17.2.1 Introduction to WirelessHART WirelessHART is a subset of the HART industrial instrument communication standard as of version…

17.1 Basic Components Common to all Radio Systems
“Radio” systems use electromagnetic fields to communicate information over long distances through open space. This section explores some of the basic components common to all radio systems, as well as the mathematical analyses necessary to predict the performance of radio communication. 17.1.1 Antennas A radio wave is a form of electromagnetic radiation, comprised of oscillating electric and magnetic…
