Wireless HART: ‘If it sounds too good to be true, …’

Speaker: Kevin Heylen & Daan Roks

Company/ Institute: Coso Softec

Event: 1st work meeting

Date: 27 May 2009


Wireless sensor networks (WSN) have been around for some time now. Mesh topology, energy awareness, robustness and reliability are key factors in a successful implementation of a sensor network. The aim of the Wireless HART standard is to combine the functionality of the industrial HART communication protocol with the advantages of a WSN for use in the conservative world of industrial automation. Wireless HART is part of the HART 7.1 standard, and focuses on a reliable, energy aware, secure and robust wireless application of the sensor network. It’s based on the TSMP protocol designed by Dust Networks.
This presentation will explain the characteristics of the Wireless HART protocol and the physical, media access and routing techniques used. We will discuss the advantages, but also the drawbacks, of Wireless HART together with the current status of the standard and implementations.
