Silicon Labs, a provider of silicon, software and solutions, announces Z-Wave Long Range (LR) support for existing Z-Wave 700 Series products. With ten-year coin cell battery operation, backward compatibility and the addition of Z-Wave LR features, Silicon Labs Z-Wave 700 Series SoCs and modules extend seamless wireless connectivity beyond the smart home.

The unique benefits of Z-Wave LR make it a perfect fit for Internet of Things (IoT) applications in commercial, multi-dwelling unit (MDU), and hospitality markets. Z-Wave LR is a new specification by the Z-Wave Alliance offering point-to-point wireless connectivity at ranges up to several miles and support for thousands of nodes.

External power amplifier

Z-Wave LR eliminates the need for mesh repeaters, saving time and money for developers and end customers. “The addition of Z-Wave Long Range support is a significant expansion of our Z-Wave 700 Series product offering, bringing Z-Wave beyond the home into IoT markets requiring substantially greater range and penetration,” said Jake Alamat, vice president and general manager of IoT home and consumer products at Silicon Labs.

Z-Wave 700 products will be launched in 2021, further extending range with an increased +20dBm output

Field testing of Z-Wave LR on Silicon Labs Z-Wave 700 Series products demonstrated one-mile point-to-point range (line-of-sight) at +14dBm output power, and new Z-Wave 700 products will be launched in 2021, further extending range with an increased +20dBm output. Several mile range can be achieved with an external power amplifier to meet the maximum Z-Wave LR specification limit of +30dBm.

Optimising power settings

Additionally, the 700 Series supports dynamic output control to optimise power settings and enables up to ten years operation on a coin cell battery. “Silicon Labs’ Z-Wave 700 solutions with Z-Wave Long Range will allow us to provide energy-efficient, scalable IoT connectivity to our smart apartment communities,” said Felicite Moorman, Co-Founder of STRATIS, an IoT platform for connected buildings.

With ease of installation and extended range capabilities, these Z-Wave solutions enable connected products that deliver an excellent experience for installers, staff and residents.” New development kits supporting Z-Wave LR are available for purchase. Software support for Z-Wave Long Range on Z-Wave 700 devices is available via Simplicity Studio 5, Silicon Labs’ free IoT developer environment. Z-Wave Alliance certification for Z-Wave LR devices will be added by end of Q1 2021, with customer products to follow.
