WirelessHART

WirelessHART is a wireless sensor networking technology based on the Highway Addressable Remote Transducer Protocol (HART). WirelessHART targets sensors and actuators, rotating equipment such as kiln dryers, environmental health and safety applications such as safety showers, condition monitoring, and flexible manufacturing in which a portion of the plant can be reconfigured for specific products. The protocol operates in the 2.4 GHz ISM band using the IEEE 802.15.4 standard radios with a QPSK modulation. The data rate can reach 250 kb/s. Communications scheduled based on Time Division Multiple Access and employ a channel hopping scheme for added system data bandwidth and robustness. The topology of the network can be mesh, star, combined star and mesh. About the security, this uses the industry standard 128-bit AES encryption and a data integrity and device authentication.
