World’s first NB-IoT module certified for use in hazourdous environments enters initial production

Thalwil, Switzerland – March 1, 2018 –  u-blox (SIX:UBXN), a global leader in wireless and positioning modules and chips, announced that its SARA-N2 ( https://www.u-blox.com/en/product/sara-n2-series ) NB-IoT module series is entering initial production. In addition to being certified for use in Europe, Asia and Australia, the module has received ATEX certification for deployment in hazardous environments, expanding the scope of the Internet of Things (IoT) to new industrial applications.

“At u-blox, we’ve been closely involved in the development of NB-IoT since its inception,” says Samuele Falcomer, Product Manager, Product Center Cellular at u-blox. “In 2016, we sent the first pre-standard message over a NB-IoT network and then went on to launch the world’s first NB-IoT module. Now, our u-blox SARA-N2 NB-IoT module series is in production, including the world’s first ATEX-certified NB-IoT module. These successes speak to our firm commitment to driving innovation in this sphere and growing the IoT ecosystem.”

NB-IoT is establishing itself as the technology of choice for many industrial IoT applications including metering and sensor applications. This is driven in part by the technology’s low power requirements, which let end devices run for years – sometimes more than a decade – on a single battery, minimizing the need for maintenance. Additionally, excellent indoor and underground signal penetration and wide-reaching coverage enable IoT applications in otherwise challenging locations such as in cellars, deep underground, or in remote areas.

The SARA-N211 product variant, which targets the European market with support of Bands 8 and 20, is the first NB-IoT module to receive ATEX-certification for use in hazardous and potentially explosive environments often encountered in the oil and gas industries, in chemical plants and in mining applications, further extending the reach of NB-IoT. ATEX pre-certification saves end-device makers time and resources by assuring compliance, while simultaneously speeding up testing and simplifying end device certification. Importantly, it minimizes the risk of last-minute changes to the module to meet ATEX demands.

The u-blox SARA-N2 module is available now.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
