NI 9792 WSN Real-Time User Guide and Specifications

Figure 18.

Network Containing Distance, Example 1

In this case, all nodes have properly meshed, and all nodes can communicate with the gateway. However,
this network could potentially strand end nodes. Figure 19 shows another possible mesh of the same
network.
