Z-Wave Alliance Announces Release of ZWLR Specification for Europe

BEAVERTON, Ore. –The Z-Wave Alliance, a standards development organization for smart home and Z-Wave technology, has announced that the specification for Z-Wave Long Range (ZWLR) for the European market has been completed and will be made available to member companies soon.

“From the moment we announced ZWLR for the North American market, the Alliance has been hard at work to make the spec available to our valued members in Europe,” said Avi Rosenthal, chairman of the board, Z-Wave Alliance. “With the specification complete, the Alliance will soon announce ZWLR certification program details and once released, ZWLR will be available to European Z-Wave Alliance members for product development.”   

Z-Wave AllianceZ-Wave said that ZWLR has been meticulously designed as a communication protocol for applications where high-performance, increased scale, low power, increased device security, range, and device interoperability are all vital. With the specification now complete, Z-Wave Alliance members operating within Europe will soon be able to capitalize on the features and benefits of ZWLR.

While the network topologies are different, Z-Wave supports both a mesh network and a star network operating within the same frequency range. Existing Z-Wave mesh and new ZWLR nodes can co-exist on the same network, enabling a wide variety and combination of Z-Wave devices capable of achieving the highest performance feature set of any wireless protocol combination.

ZWLR devices operate on a star network topology which features the gateway/hub at a central point and then establishes a direct, point-to-point connection to end devices. The direct communication path established by the star network topology provides a substantial decrease in latency between the gateway/hub and end point devices.

The Z-Wave mesh and ZWLR have been designed to co-exist and complement each other according to the Alliance. By operating on a star network, ZWLR enables direct gateway-hub-to-device connection across increased distances, whereas mesh traditionally permits signal to hop from node to node until the intended destination is met. With ZWLR, simplified routing enables commands to go through faster and potential failures within the network are highlighted quickly as well. With Z-Wave, manufacturers have access to the “self-healing” properties of mesh networks and the direct communication benefits of a star network.

Additionally by increasing the addressing space to 12-bit, ZWLR is capable of supporting up to 4,000 nodes on a single network. Compared to Z-Wave (232 nodes), this represents a 20x increase in network node availability. Another improvement to ZWLR offers end point devices battery life of up to 10 years off a single coin-cell battery by leveraging dynamic power control. This feature enables ZWLR devices to automatically adjust and optimize the radio output power of every transmission.
