NB-IoT Module is Ready for 3GPP Release 14 and 5G

U‑blox 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. That means it is well suited 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. That enables users to do feature customization by scripting their own configurable objects.

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.
