LARA-R3121 - Size-optimised LTE Cat 1 single-mode module with GNSS receiver

Complete cellular connectivity and positioning solution optimised for IoT

The LARA-R3121 LTE Cat 1 module is a pioneer, as the only module designed from the ground up for IoT applications. At its core is the UBX-R3 chipset, u-blox's own cellular modem with silicon-integrated GPS receiver.

The UBX-R3 platform uniquely provides a wide range of features for secure and robust operation, such as secure boot, transport layer security, embedded FOTA client for secure software updates over the air, jamming and spoofing detection.

Based on u-blox's innovative software-defined modem engine, LARA-R3121 offers advanced 3GPP features, such as Rel. 12 Power Saving Mode for long battery life, Extended Access Barring (EAB) feature for signaling optimization/ congestion control, and QoS enhancement for mission critical applications.

Thanks to the integration of a u-blox 8 GPS receiver directly in the UBX-R3 chipset, LARA-R3 cost-effectively provides highly reliable and accurate positioning data both indoors and outdoors. In addition, LARA-R3121 offers unique hybrid positioning, in which GPS position is enhanced with u-blox CellLocate® location data.


  • Supports 3GPP Rel. 12 Power Saving Mode for long battery life
  • Provides accurate and reliable position data indoors and outdoors
  • Features end‑to‑end trusted domain security
  • Provides signal optimization and congestion control
  • Enables easy migration from other u‑blox module form factors and technologies
