3.4.2 Viewing Network Formation

The following sequence of figures shows how network formation appears on the NCD

window.

First, the ZigBee protocol coordinator sends a beacon request.

FIGURE 3-20: NCD BEACON REQUEST

Since there are no nodes on this channel, no beacons are received, and the ZigBee

protocol coordinator forms a network.

Next, a ZigBee protocol router tries to find a network to join. It also emits a beacon

request, which looks just like Figure 3-20, since the beacon request contains no source

address information. Now, the ZigBee protocol coordinator responds with a beacon.
