u-blox SARA R410M 83B dual-mode cellular module for IIoT

u‑blox has announced certification of its dual-mode SARA‑R410M‑83B module for Australia on Telstra’s LTE‑M and NB-IoT cellular network. The module will suit a broad spectrum of IoT applications such as smart metering, telematics, asset and vehicle tracking, security systems and connected health. With frequency bands 3, 5, 8, 20, 28, conformance to RED and certification for NCC, it can also be used in Europe and Taiwan.

Recently introduced NB-IoT features have been tested and approved by Telstra. Release Assistance Indicator gives the application the option to terminate the connection as soon as the uplink message is sent.

The ability to release the network connection quickly and reduce power consumption is useful for those requiring extended battery life, particularly in remote areas. u-blox’s customised implementation of embedded secure MQTT protocol enables quick development of secure data transmission to AWS and MS Azure cloud platforms. The immutable root of trust and lightweight key exchange make the modules suitable for mission‑critical IoT solutions, providing the foundation for a trusted set of advanced security functionalities.

The scalable, pre-shared key management system offers good data encryption and decryption, on-device as well as from-device-to-cloud. Utilising the latest (D)TLS stack and cipher suites with hardware-based crypto acceleration provides robust, efficient and protected communication.

Users can futureproof their solutions by means of uFOTA (firmware over the air) client/server firmware updates using LWM2M, a light and compact protocol for IoT applications. uFOTA is a complete end-to-end u-blox service for remotely updating deployed modules to future firmware releases, with additional security provided between module and server via pre-shared secure keys. With manufacturing in ISO/TS 16949-certified production sites in Europe and an extended operating temperature range of -40 to +85° C, it is suitable for secure long life industrial applications.
