WirelessHART is a wireless communication protocol designed for industrial automation and process control. It enables devices, such as sensors and actuators, to communicate wirelessly in challenging environments, providing a reliable and secure way to transmit data. This technology is particularly useful in industries like oil and gas, chemical, and manufacturing. The WirelessHART protocol operates in the 2.4 GHz frequency band and uses a mesh networking approach, allowing devices to relay information to one another. This enhances coverage and reliability, ensuring that data is transmitted even in areas with obstacles or interference.
