Overview
The NI WSN-9791 Ethernet gateway coordinates communication between
distributed NI WSN-32xx measurement nodes and a host controller in your NI
wireless sensor network (WSN). The gateway uses a 2.4 GHz, IEEE 802.15.4
radio to gather measurement data from the sensor network and a 10/100 Mbits/s
Ethernet port to provide flexible connectivity to a Windows PC or NI LabVIEW
Real-Time PAC, as seen in Figure 1.
With this flexibility, you can create simple, stand-alone wireless monitoring
networks or completely integrated wired and wireless measurement solutions
that feature access to the full breadth of NI hardware and software platforms.
LabVIEW integration with NI WSNs delivers a common development
environment for your applications as well as rapid application development,
easy network configuration, remote data access, and the ability to program and
customize measurement node behavior.
The 9 to 30 VDC externally powered gateway offers -30 to 70 °C operating
temperatures, 50 g shock ratings, and a compact, 2U form factor. Up to
36 measurement nodes can communicate with a single gateway, and you can
configure the Ethernet settings of the gateway for DHCP, static, and link-local
IP address configurations.
Wireless Networking
The NI WSN system is built on a low-power, reliable IEEE 802.15.4 network.
The Ethernet gateway coordinates the wireless network, performing functions
such as device authentication, message buffering, and network topology
administration.
The gateway, routers, and end nodes work together to form a mesh network.
Measurement nodes can operate as routers or end nodes, providing the flexibility
to extend the range of your sensor network. When nodes are configured as
routers, they can repeat messages from end nodes and extend network range

host controllers.
