![]() The Z-Wave uses a source-routed mesh network which consist of the one primary node – often referred to as the controller or hub in Home Automation, and many other secondary nodes referred to as sensors. The longer wavelength and lower frequency of the Z-Wave allow it to easily penetrate objects and walls, thereby establishing a more reliable and faster communication topology between the connected Z-Wave devices. However, since it operates in the low-frequency region, Z-Wave offers superior performance. Due to band constraints in different geographies, Z-Wave is a region specific protocol, which means it has different legally permissible frequencies in different regions. Unlike the ZigBee protocol that works at 2.4GHz wireless frequency, Z-Wave operates at in 900 Mhz frequency bands. It’s currently being used by more than 300 plus manufacturers and thousands of devices, making it one of the most popular communication protocol after ZigBee. Used in a variety of smart home applications like lighting, security, entertainment and others, it’s one of the upcoming new communication standards in the world of Internet-of-Things (IoT). Z-Wave technology is the new wireless communication protocol for home automation devices.
