Technology Standards Comparison

Nivis actively supports the ISA100.11a, WirelessHART and Smart Object wireless mesh network standards with both software and hardware. At present we do not support the Zigbee standard, because we believe the first three are clearly superior.

Any of the three main standards can be used for any application. In general, Nivis finds that WirelessHART is a good choice for applications needing to interact with a preponderance of existing HART and WirelessHART devices. ISA100.11a is a great all-round technology, especially for industrial and process automation applications. Smart Object was developed specifically for the Internet of Things: applications requiring potentially tens of thousands of IPv6-addressable sensing and controlling devices.
