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.
