- More than 30 million devices worldwide use the HART communication protocol.
- WirelessHART is a radio communications protocol that adds wireless capabilities to the HART protocol while maintaining compatibility with existing HART devices, commands, and tools.
- WirelessHART utilizes a time synchronized, self-organizing, and self-healing mesh architecture.
- WirelessHART supports operation in the 2.4 GHz ISM (license free) band using IEEE 802.15.4 standard radios.
- In a WirelessHART network, every participating device simultaneously works as a signal source and a data repeater.
- Through the routing of the individual signals across the entire network, a wide network structure becomes possible.
- Data repeaters (routers) can be strategically placed to expand the network reach throughout the facility or field application.
There are three main elements in any WirelessHART network:
- Wireless field devices connect to plant equipment.
- Gateways enable communication between these devices and hosted applications.
- A network manager, typically integrated into the Gateway, is responsible for configuring the network and managing communication and message routing.
