6.1 Introduction to the ZigBee Protocol
The ZigBee PRO specification was ratified in April, 2007, and covers high-level commu-
nication protocols for small, low-power digital modems based on the IEEE 802.15.4 stan-
dard for wireless personal area networks (WPANs). The XBee RF module used by the
BL4S100 and the BL4S150 operates in the 2.4 GHz industrial, scientific, and medical
(ISM) radio band in most jurisdictions worldwide.
The ZigBee protocol is ideal for embedded-system applications that are characterized by
low data rates and low power consumption. A network of devices using the ZigBee proto-
col works via a self-organizing mesh network that can be used for industrial control,
embedded sensors, data collection, home security, and building automation. The power
consumption of the individual device could be met for a year or longer using the originally
installed battery.
A ZigBee device can be set up in one of three ways.
• As a coordinator: The coordinator serves as the root of the network tree. Each network
• As a router. Routers pass data from other devices.
• As an end device. End devices contain just enough functionality to talk to their parent
BL4S100 User’s Manual
can only have one coordinator. The coordinator stores information about the network
and provides the repository for security keys. The coordinator starts a ZigBee network
and then acts as a router once that network is started.
node (either the coordinator or a router), and cannot relay data from other devices.
Chapter 6 discusses using the ZigBee features on the BL4S100
and the BL4S150 models. This networking feature is not avail-
able on other BL4S100 models.
