ST radiochip understøtter nu også Sigfox-teknologien

Low-power, langtrækkende radiochip fra STMicroelectronics tilbyder udvide IoT-rækkevidden gennem support af Sigfox kommunikationsteknologien (in english).

ST’s new S2-LP transceiver is ideal for networked devices, such as alarm systems, surveillance equipment and smart energy-metering solutions, as well as long-range radio links used to connect devices like remote sensors directly to the Cloud without a local gateway. Other applications include building automation, industrial monitoring and control, and systems for managing lighting, traffic, or parking in smart cities.

The device operates in unlicensed sub-1GHz frequency bands, which are available globally. Ultra-narrowband operation allows highly efficient use of radio spectrum and reliable data exchange up to long distances using low-power signals.

In addition, the transceiver enables connectivity to the Sigfox global network, which is being rolled out worldwide to provide a reliable cost- and energy-efficient communication solution for billions of sensors and smart things.

- Building on our strengths in MEMS sensors, analog and microcontrollers, in 2009 we saw the coming need to support emerging IoT applications with a low-power ISM radio for medium-long-range wireless connections and we developed and introduced our own SPIRIT1 low-power sub-1GHz radio that is currently in many applications available in the market, says Benedetto Vigna, Executive Vice President, General Manager, Analog and MEMS Group, STMicroelectronics.

- Now, in partnership with Sigfox, we are opening a new era in ISM radios for the IoT to extend battery life from months to more than 10 years while preserving the robustness and reliability of the connection and reducing maintenance costs for remote and difficult-to-reach sensors.

Tony Francesca, Vice President of Global Ecosystem Partners at Sigfox adds:
- Our global network, which has been optimized for the lowest device energy consumption and cost, provides an entirely new way of connecting the physical world to the Cloud. ST’s support for Sigfox, integrated in the new S2-LP radio device, will help system designers bring their IoT concepts to life by leveraging the benefits of our fast global infrastructure and ecosystem.

The S2-LP long-range, low-data-rate transceiver is in production now in a 4mm x 4mm QFN24 package.
