NI 9792 WSN Real-Time User Guide and Specifications

Mesh Configuration Example

In this configuration, R

1

 (a router) and R

2

 (a router) both communicate directly with the gateway. 

Measurements taken by both devices can directly reach the gateway without having to hop through 
another node. However, the configuration above does not always mesh in the same way. Figure 15 shows 
another possible configuration for the same network.
