Wireless Sensor Network Ethernet Gateway

NI WSN-9791

◾ ◾

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.

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.

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

while acquiring measurement data.

With this flexibility, you can create simple, stand-alone wireless monitoring

The 9 to 30 VDC externally powered gateway offers -30 to 70 °C operating

The gateway, routers, and end nodes work together to form a mesh network.
