Section 4 Functional Overview
This section describes how the software furnished with the kit is used to demonstrate a
simple IEEE 802.15.4 network operating with a star topology. The star network is
shown below in Figure-4.1 and consists of a Personal Area Network (PAN) Coordinator
and a number of End Devices (in the case of this kit). The distinguishing feature of a
star network topology is that communication between End Devices is always routed
through the PAN Coordinator. Direct communication between End Devices is never
allowed.

Channel Scan
The process of creating a network begins with the PAN Coordinator. Upon power up,
the PAN Coordinator must select a channel on which to create its network. The PAN
Coordinator does this by broadcasting a Beacon Request message. The PAN Coordi-
nator repeats this broadcast on all channels from 11 to 26 in search of a channel without
a PAN Coordinator. If the channel is in use by another network, that networks PAN
Coordinator will respond with a Beacon. However, if the channel is unoccupied, the
Beacon Request will not be answered. By default, the lowest unoccupied channel of the
scan becomes the channel on which the network will form.
