The WirelessHART network is built up, organized and maintained by the WirelessHART
Gateway and is therefore self-organizing and self-healing. The Gateway also takes care for
connection to different host systems through different industrial protocol bus interfaces.
The WirelessHART Gateway supplies the WirelessHART field devices with the necessary
information for seamless network operation.
