Z WAVE

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.

What is Z-Waves 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.

www.ppttopics.com

Z-Wave operates on a variety of sub-GigaHertz frequencies throughout the world: Australia: 921.42 MHz China: 868.42 MHz CEPT*: 868.42 MHz India: 865.22 MHz Japan: 951-956 MHz Hong Kong: 919.82 MHz Malaysia: 868.10 MHz New Zealand: 921.42 MHz Singapore: 868.42 MHz UAE: 868.42 MHz USA/Canada: 908.42 MHz Brazil: 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
