LTE Cat 1 module for IoT cellular wireless links

September 23, 2016 // By Graham Prophet
Developed from the ground up by Swiss company u-blox, the UBX-R3 platform delivers IoT cellular connectivity. The platform is at the heart of the first Cat 1 LTE module, LARA-R3, marking the first milestone in a long-term strategy to establish leading LTE modem technology designed specifically for both the IoT and for M2M communication.

The LARA-R3 module series is positioned as the only cellular product in the market to feature a combination of a Cat 1 LTE modem and GNSS technology, all developed by a single supplier.


The LARA-R3 product series is a single-mode LTE Cat 1 module based on the UBX-R3 LTE modem technology platform. It complements u-blox’s existing multimode LTE Cat 1 portfolio, which consists of the LARA-R2 and TOBY-R2 module series. LARA-R3 also provides positioning information based on an on-board GNSS receiver. It is built for long-term availability, with full component traceability. The software-defined modem architecture in the UBX-R3 modem platform offers specific features for IoT, such as power minimization, signalling optimization and load and throughput control, all compatible with latest standards releases. System complexity has been adapted for LTE-only support and the device can be modified to meet specific customer requirements.


The new platform can support end-to-end security features (secure firmware boot, secure transport layer, secure interfaces, secure APIs) that are tightly integrated within the LARA-R3 module.
