New from u-blox is the LARA-R3121, a module comprising a single-mode LTE Category 1 modem and a GNSS (global navigation satellite system) positioning engine specifically designed for IoT and M2M devices. The versatile device is ideal for IoT applications including smart utility metering, connected health and patient monitoring, smart buildings, security and video surveillance, smart payment and POS systems, as well as wearable devices such as action cameras.
LARA-R3121 is supplied in the small 24 x 26 mm LARA LGA form factor, ideal for compact IoT devices. This standardised package enables straightforward automated manufacturing, and it is pin-compatible with the u-blox LARA-R2 series, which supports multimode LTE Cat 1 with 2G/3G fallback. It is a first landmark in u-blox’s long-term strategy to create modules based on the UBX-R3 LTE modem technology platform, an internally developed, flexible, software-defined modem architecture specifically designed for IoT and M2M.
The new module features FOTA, providing customers with a solution to issue firmware-over-the-air updates. It also benefits from end-to-end security features, such as secure boot, secure transport layer, secure authentication, secure interfaces and APIs. Like other cellular modules from u-blox, it complies with a nested architecture, which allows for easy migration, and future-proof, seamless mechanical scalability across cellular technologies.
As a single-mode, LTE-only device, LARA-R3121 takes advantage of the fact that LTE networks are becoming universally available. Increasingly, products do not require fallback to 3G or 2G, which means that non-essential components can be removed, reducing cost and power consumption. The 10 Mbps downstream and 5 Mbps upstream maximum throughput of LTE Cat 1 provides data rates sufficient for good quality video streaming.
