|Z-Wave®, the international standard for home automation is implemented in around 1500 different products from various vendors. The Z-Wave® label ensures that all these products work together and form the world largest eco system of wireless home network controls.|
|Z-Wave® uses different frequencies in different parts of the world. While North America is using the ISM Frequency band of 908 MHz, all European Countries, the Middle East, Africa and most of the Asian countries including Peoples Republic of China use the so called SRD (Short Range Device) Band with the frequency of 868.42 MHz.|
|All Z-Wave® devices need to be certified by the Z-Wave Alliance to ensure interoperability. This goes beyond the use of the same frequency and includes a wide range of requirements to make sure that products from different vendors can really work together in one single home network.|
How does Z-Wave work?
|All communication is encrypted and confirmed by the receiver. Every device can forward message on behalf of other nodes (mesh network). Z-Wave is using the designated frequency in a standardized way. This standard is issued by th ITU T under the number G.9959.|
|Can be used both for mains powered and for battery powered devices. Devices like temperature sensors, motion sensors, humidity sensors, shock sensors, door sensor, remote controls and wall controllers are mostly battery powered. Other devices for shutter control, light control, heating and gateways are main powered by being connected to power cable.|
|Z-Wave uses 868,42 Mhz frequency band dedicated to home control. Using sub 1 GHz frequency avaoiding the heavily congested 2.4 GHz and 5 GHz bands where WLAN and ZIGBEE are positioned.|
Why is Z-Wave special?
|Z-Wave is adopted by more than 350 vendors worldwide. Companies all over the world are members of the Z-Wave Alliance. By using the Z-Wave standard you have the benefit to choose from different local or foreign companies to build your own Z-Wave network.|
|Z-Wave devices from different vendors and different applications work together in one wireless network. Z-Wave certification allows devices from different producers and vendors to interoperate with each other.|
