1.3 ZigBee in the Marketplace ZigBee is beginning to be found in many,

many applications.

Application

Home Automation Commercial Building Automation Industrial Plant Monitoring Automatic Metering Initiative Personal Home and Health Care Telecommunications Applications

5

Telecom Application Information Services

These services could advertise specials, services, or sales (at your option) based on the location of your cell phone.

1.4 Hello ZigBee (A First ZigBee Network) The concept of this example is very

simple.

7

So what happens from a ZigBee perspective? The HA OnOffLight Zigbee Coordinator (Z

C) forms the network. The HA OnOffSwitch joins the network. The HA OnOffSwitch finds the light and bi

nds to it. The HA OnOffSwitch can toggle the light

with SW1.

8

Packet sequence number If you look at Seq. No. 5, you’ll see the H

A OnOffSwitch joining the network with an Association Request.

Look at Seq. No. 11 and you’ll see the HA OnOffSwitch sending out the Match Descriptor request. It receives the response on Seq. No. 17, and now knows where the light can be found in the network.

Four frames in this packet The IEEE 802.15.4 (or MAC) frame

responsible for the PAN ID and the per-hop information

The ZigBee network (NWK) frame responsible for multi-hop communication

The ZigBee application (APS) frame responsible for the applications

The ZigBee Cluster Library (ZCL) frame contains specific application commands

12

Abbreviated source code If the HA OnOffSwitch is started first, it will kee

p trying to join until the HA OnOffLight forms the network, then the switch will join it

ZigBee communicate Individual nodes. Group. “Identify” mode.

ZigBee devices remember their settings across resets and power outages.

1.7 ZigBee Architecture

19

ZigBee model PHY layer

Simply translates packets into over-the-air bits and back again MAC layer

Provides the concept of a network, including a PAN ID. Not multi-hop or mesh.

NWK layer Mesh networking. Broadcasting packets . Encrypted.

APS layer The APS layer also filters out duplicate messages that may

have been sent up by the NWK layer. ZDO layer

It provides services to discover other nodes and services in the network.
