The WSN-9791 is not recommended for new designs. We recommend that you instead consider the NI 9792 programmable wireless sensor network (WSN) gateway, which adds increased capabilities over the WSN-9791, including the ability to run local LabVIEW Real-Time applications for data processing, communication with other devices, or integration with human machine interfaces, EtherCAT slaves, local sensors, or the enterprise.

The WSN-9791 Ethernet gateway coordinates communication between distributed measurement nodes and the host controller in your NI WSN. The gateway has a 2.4 GHz, IEEE 802.15.4 radio based on ZigBee technology to collect measurement data from the sensor network and a 10/100 Mb/s Ethernet port to provide flexible connectivity to a Windows or LabVIEW Real-Time OS host controller. The NI-WSN software included with the WSN-9791 helps you quickly configure your sensor network and extract, analyze, and present your measurement data using the LabVIEW graphical development environment.

The rugged, 9 VDC to 30 VDC externally powered gateway (power supply not included) offers -30 °C to 70 °C operating temperatures; 50 g shock and 5 g vibration ratings; and a compact, 2U form factor. The external antenna supports an outdoor range up to 300 m with line of sight, and can accommodate 8 end nodes in a star topology or up to 36 nodes in a mesh topology.

Wireless products require certification based on the geographic region of use. Consult the Wireless Product Certifications document linked from the Resources tab to determine which products are certified in your region.
