Day 1 of Works With got off to a fast start today with the launch of Z-Wave Long Range (LR), which extends wireless range by 4 times, and brings the Z-Wave technology beyond the home. The new specification not only improves wireless range for products such as door locks, garage door sensors, gate access solutions, security sensors and other applications, but also increases scalability to more than 2,000 nodes on a single wireless network.
Coverage, Scalability, and Battery Life
The Z-Wave Long Range specification is just the first development planned within the new Z-Wave Alliance Standards Development Organization and it brings big improvements to the features IoT developers care about most – more coverage, extended scaleability, and longer battery life. One of the big advantages of subGHz today is that it is already longer range than 2.4GHz due to better peneration; now Z-Wave Long Range further extends this benefit by increasing the range with 4X (using the Silicon Labs Z-Wave 700 platform), removing the need for mesh/repeaters, thus saving on the system cost. Z-Wave Long Range also increases scalability on a single smart home network to over 2000 nodes – a 10x increase – and a big step in supporting the massive growth in adoption. Finally, dynamic power control optimizes operation of devices so Z-Wave Long Range enables sensor lifetimes up to ten years on a coin cell battery.
Security and Compatibility
The Z-Wave Long Range specification will be managed and certified under the Z-Wave Plus V2 certification program, which currently mandates the inclusion of the enhanced S2 security framework as well as SmartStart, a setup feature that enables true plug and play for the consumer smart home. As with all certified Z-Wave devices, Z-Wave Long Range devices can be installed within any Z-Wave network and features interoperability and backwards compatibility with any previously installed Z-Wave device.
What’s Next for Z-Wave Long Range?
There are currently three alpha customers testing the standard, and we’re looking forward to pushing this specification as far as possible. Want to learn more?
