Developed and managed by the new Z-Wave Alliance Technical and Certifications workgroup, within the Z-Wave Alliance, the new Z-Wave Long Range (Z-Wave LR) specification will enable expanded options for the smart home, multi-dwelling units and hospitality use cases.
Engineered to provide significantly extended wireless range and support robust networks, Z-Wave LR extends Z-Wave connectivity beyond the interior boundaries of the home to improve wireless transmission range of peripheral Z-Wave devices such as door locks, garage door sensors, gate access systems, and more, while increasing scalability to over 2000 nodes on a single smart home network.
To ensure complete home or building coverage, or to expand the network into the yard, most Z-Wave installations today leverage Z-Wave repeaters to strengthen and expand coverage. Z-Wave LR eliminates the need for a repeater within the network by increasing the transmission range found in Z-Wave. Increased range unlocks new potential for Z-Wave networks, making it easier than ever before to enroll smart home and IoT devices deployed at the end of the yard or beyond for enhanced functionality.
As the average number of installed smart home devices continues to increase, so too does the strain on the network. To support the upward trend in the number of sensor and IoT devices within homes and MDU environments, Z-Wave LR also increases scalability on a single smart home network to over 2000 nodes – a 10x increase from Z-Wave.
With dynamic power control to optimize operation, Z-Wave LR increases typical sensor use cases on a coin cell battery up to ten years.
