Wireless is unleashing the next wave of industry transformation due to its inherent flexibility, scaleability, and efficiency for improvement of distributed sensing and control systems. Proprietary wireless transmitters have existed in plants for many years but always focused on point-to-point cable-replacement applications. Now wireless networking is being realised in industrial process control since WirelessHART™, designed by the leading suppliers of instrumentation for the process control industry, has been recently approved. WirelessHART, the only approved standard, enables standards-based wireless networking for process automation, allowing confident and broad implementation of reliable, secure wireless technology. WirelessHART enables pervasive connectivity among sensors and actuators, with a field-proven reliability greater than 99% and a secure self-organising network. As a highly engineered solution, WirelessHART supports the full range of control and monitoring solutions, allowing process owners and operators to start using the growing set of wireless applications today and scale up as a plant-wide range of traditional and advanced functions are developed and offered by the variety of global instrumentation suppliers.
