u-blox, a global provider of leading positioning and wireless communication technologies, has announced the SARA-N3, a multi-band NB-IoT module that supports a preliminary set of 3GPP Release 14 features (LTE Cat NB2). The SARA-N3 is available in two variants: one dedicated to China and another that can operate across multiple bands on any NB-IoT network globally.

The u-blox firmware-over-the-air (uFOTA) client/server solution with Lightweight M2M (LwM2M) allows SARA-N3 to be remotely provisioned with additional features. LwM2M is a more lightweight solution as compared to OMA-DM and thereby ideal for providing critical firmware updates to IoT devices. In this way, SARA-N3 can ultimately become 5G compliant. SARA-N3 also supports the creation of dynamic LwM2M objects, giving customers high levels of feature customization through the ability of scripting their own configurable objects.

With its feature-rich capabilities, the SARA-N3 enables the development of one device across multiple regions for a wide variety of IoT/IIoT applications such as metering, smart city smart city systems, smart homes and industrial trackers,

says Samuele Falcomer, Senior Product Manager, Product Center Cellular at u-blox.

For customers currently using other methods to send IoT/IIoT data, such as legacy cellular technology, it is simple to upgrade to SARA-N3 through u-blox nested design and the new features introduced. The product is future-proof, as it can receive further firmware upgrades over the air.

The SARA-N3 provides a comprehensive set of features and protocols that NB-IoT-based applications will benefit from, including TCP, HTTPS, CoAP, DTLS and MQTT. With its ultra-low power consumption profile and the ability to configure voltage domains, the module is optimized to operate on a single cell primary battery for 10+ years, eliminating the need for frequent maintenance visits. Other features include a ‘last gasp’ function that lets the module send one last message should the power fail unexpectedly and protection against software attacks by detecting potential jamming signals.

u-blox manufactures according to ISO/TS16949 professional grade specifications. This approach incorporates 100% automated x-ray and optical inspections, 100% outgoing test and product traceability. Together with failure analysis and product qualification criteria ensures that highly reliable products designed for long-term operation are created.
