u-blox has announced the SARA R5 series of LTE M and NB-IoT modules for low power wide area (LPWA) IoT applications. The module, built on the UBX R5 cellular chipset and the M8 GNSS receiver chip, is the company’s most advanced, secure and highly integrated cellular product to date,
The secure element is compliant with EAL5+ High common criteria certification, which makes the module well suited to protect sensitive assets and communications. It also features a lightweight and low-power pre-shared key (PSK) management system that is tailored to the needs of IoT applications, along with a comprehensive set of security features.
With mobile network operators announcing their plans to roll out 5G networks, 5G readiness is becoming a key factor in selecting cellular communication modules. LTE M and NB-IoT are forward compatible with 5G networks and, by implementing key LTE M and NB IoT features from 3GPP Release 14, SARA R5 offers customers a smooth transition towards 5G via software upgrades to already deployed devices.
SARA R5 comes in two product variants. Featuring a built-in M8 GNSS receiver, the R511M targets mobile applications in the automotive, fleet management, tracking and telematics sectors. The GNSS receiver’s chip-down design includes a dedicated GNSS antenna interface and can run in parallel with the cellular connection.
The second product variant, SARA R510M, is optimised to deliver the lowest achievable power consumption, drawing less than 1 µA of current in power save mode, making it ideal for metering, smart city, connected health, security and surveillance, remote monitoring and other battery powered applications.
