What are the application of Zigbee?
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need …
What is Zigbee technology example?
Zigbee Technology is based on IEEE 802.15. 4 Standard and the Zigbee devices operate in the unlicensed 2.4 GHz ISM Band (ISM – Industrial, Scientific and Medical). For example, the 868 MHz band supports a data transfer rate of 20 kbps while the more common 2.4 GHz band supports data rates up to 250 kbps.
Which management task is defined by Zigbee device object?
ZigBee device object (ZDO): A ZigBee device object performs control and management of application objects. The ZDO performs the overall device management tasks: Determines the type of device in a network (for example, end device, router, or coordinator) Initializes the APS, network layer, and security service provider.
What is the main advantage of using Zigbee?
Advantages of Zigbee networks : Zigbee has a flexible network structure. It has very long battery life. Zigbee has a mesh network topology with low cost, multi hope data transmission and is power effective. It is less complex than Bluetooth.
What is Zigbee technology discuss in detail about Zigbee architecture and its application areas?
Zigbee architecture is a combination of 6 layers. The Application layer is present at the user level. The Application Interface Layer, Security Layer, and Network Layer are the Zigbee Alliance and they are used to store data and they use the stack. Medium Access control and the Physical layer are the IEEE 802.15.
What is Zigbee topology?
Zigbee network topology can be divided into three types. There are star topology, tree topology and peer-to-peer or mesh topology. Each topology will have different affect on how the messages are routed and which devices connect to which devices. Star topology consist of a coordinator and few end devices.
What is ZigBee architecture?
Architecture of Zigbee: The Application layer is present at the user level. The Application Interface Layer, Security Layer, and Network Layer are the Zigbee Alliance and they are used to store data and they use the stack. Medium Access control and the Physical layer are the IEEE 802.15.
How does ZigBee technology work?
Zigbee works by the coordinator, situated at the root of the Zigbee network, sending a message to a router which then passes the message on to an end device with instructions to perform a specific task. It is a wireless technology standard that is well suited for short-range wireless communications.
What can you do with ZigBee technology?
With Zigbee Technology Applications, you can control your essential home appliances. Zigbee Technology Applications lets you control and manage your house lighting from anywhere. For example, you can switch off the light in the living room right from inside of your bed room.
What types of Zigbee applications doesappbuilder support?
AppBuilder currently supports six Zigbee application profiles: • Zigbee 3.0 • Home Automation (HA) • Smart Energy (SE, formerly AMI or Automated Meter-reading Infrastructure) • Commercial Building Automation (CBA) • Zigbee Light Link (ZLL) • Health Care (HC) Clusters Each Zigbee cluster defines an application-level protocol.
Why can’t we use ZigBee in urban areas?
Because anything that might block a physical object from traveling could also block an RF. Technology can help decode some obstructed signals, but movement can still interfere. Street lighting and electric meters in urban areas can do well with mesh network, and thus work for ZigBee applications (and other mesh technologies).
What is the Zigbee application framework (ZCL)?
The Zigbee application framework (also known as the ZCL application framework) is a body of embedded C code that can be configured by the AppBuilder tool to implement any Zigbee Cluster Library (ZCL) application. The application framework is located in the app/frame- work directory.
