Z-Wave Long Range 1600 Metres 4000 Nodes.
Z-Wave Long Range 1600 Metres – Z-Wave Long-Range extends Z-Wave connectivity beyond buildings and is designed to push Z-Wave device uptake into verticals such as light commercial, hospitality, multi-dwelling units, rural applications and more.
Z-Wave Long Range is an extra 100kbps DSSS OQPSK modulation addition to the existing Z-Wave protocol. The modulation is treated as a 4th channel – allowing gateways to add LR nodes to the existing Z-Wave channel scanning. Z-Wave LR is only available for the US market presently, but the Z-Wave Technical Workgroup is evaluating and testing to ensure compliance to support Europe and APAC regions.
For installers the most exciting benefit of Z-Wave LR is the big increase in transmission range in ideal conditions. The specification supports a maximum output power of 30dBm which can be leveraged to bolster range capabilities and support future transmission distance up to 3000 metres.
Z-Wave Long Range 1600 Metres
In the first implementation of Z-Wave LR – from Silicon Labs through the 700 Series platform – a proven transmission distance of 1600 metres direct line of sight is delivered at an output of +14dBm. Prior to Z-Wave LR, multiple signal repeaters would need to be installed within a network to achieve transmission distance beyond the boundaries of the home. Z-Wave LR eliminates the need for these repeaters.
Z-Wave LR also increases scalability on a single smart home network up to 4000 nodes. Compared to Z-Wave (232 nodes), this represents a serious 20x increase in network node availability. Larger network support enables the addition of potentially thousands of Z-Wave devices on a single network, which is pretty awesome if you ever need it.
Z-Wave LR offers up to 10-year battery life on a single coin-cell type battery by leveraging dynamic power control. This new feature enables the Z-Wave Long Range device to automatically adjust and optimize the radio output power at every transmission. This 10-year battery life allows devices to be installed in out of the way places, though button batteries have risks and environmental costs.
Z-Wave LR devices operate on a star network topology which features the gateway/hub at a central point and then establishes a direct connection to devices.
