• What is Z WAVE??? Z-Wave is an efficient,

lightweight wireless technology designed for residential control applications.

Z wave working

• Makes appliances remote controllable.• Uses common “language” to communicate.• Adopted to almost any electronic device.• All devices can be used in a single event.• Event includes major or minor operations.

Getting started with Z-wave

• can start with a basic kit to control one task.• Depending on usage tasks can be multiplied.• Based on the signal strength, range(distance)

of tasks can be expanded.• A max of 232 devices are supported by a

single network.• Networks can be interconnected.

• Collection of nodal points forms mesh network.• medium for 2-way communication b/w devices.• Each device can send or receive signal from peer devices• Commands travel through mesh nodes.• Two types of nodes. 1) AC supplied. 2) Battery powered.

What is a Mesh Network?

Home Mesh

• The picture depicts a home in which Z-wave technology is implemented.

• Nook and corner is provided with nodes to enable signal transmission every where.

Setting a Z-wave network

• A Main controller is first established.• Devices to be connected are detected.• They are equipped with Z-wave hardware and

software.• Now these devices are paired and added to

the network .• Each device works as per the instructions of

the controller.

What is routing?

• Z-Wave is a routing protocol, which allows commands to be routed from one node to another until the command reaches its end-destination. This feature is very useful to extend range, and is also used to route commands around sources of interference. The result is a very reliable and robust network that can provide full home and yard coverage.

Z wave controllers

• What is Z-Wave’s range? While environmental factors such as home

construction affect the maximum communication lengths between two Z-Wave devices, you can expect around 90 feet indoors, and up to 300 feet outdoors in the open. Because Z-Wave is a “routing” technology, one Z-Wave device can pass the signal along to another until the final destination is reached. This relay system greatly extends overall range of the network.

What is contained in a Z-Wave single chip

• A Z-Wave single chip is a highly integrated mixed-signal system-on-chip. The main blocks are:- Radio transceiver- Microprocessor- 32kB flash memory, containing the Z-Wave protocol and the application- System interfaces, including digital and analogue interfaces to connect external devices such as sensors.- A 3DES engine to ensure confidentiality and authentication (100 series)- Triac controller, to reduce the module cost of dimming applications

• Radio specifications:• Bandwidth: 9,600 bit/s or 40 kbit/s, fully

interoperable• Modulation: BFSK• Range: Approximately 100 feet (or 30 meters)

assuming "open air" conditions, with reduced range indoors depending on building materials, etc.

• Frequency band: The Z-Wave Radio uses the 900 MHz ISM band: 908.42MHz (United States); 868.42MHz (Europe); 919.82MHz (Hong Kong); 921.42MHz (Australia/New Zealand).

How fast does data move over a Z-Wave network?

• The Z-Wave protocol is designed to run at 9600 bits per second. A typical control instruction to switch or dim a light is only a few bytes in length, and so response times are very fast.

• Z-Wave operates on a variety of sub-GigaHertz frequencies throughout the world:

Australia: 921.42 MHzChina: 868.42 MHzCEPT*: 868.42 MHzIndia: 865.22 MHzJapan: 951-956 MHzHong Kong: 919.82 MHzMalaysia: 868.10 MHzNew Zealand: 921.42 MHzSingapore: 868.42 MHzUAE: 868.42 MHzUSA/Canada: 908.42 MHzBrazil: 908.42 MHz

Applications:

Some common applications for Z-Wave include:• Remote home control and management• Energy conservation• Home safety and security systems• Home entertainment
