RN91xx automotive-grade 5G Rel15 module

The RN91xx module delivers global coverage for 5G Rel15. It supports SA/NSA network architectures and provides C-V2X (modem) and DSDA features.

RN91xx supports 5G sub-6 bands, LTE-FDD, LTE-TDD, WCDMA and 2G, covering worldwide networks with 3 regional variants (NA, EU, and CHN-JP), with optional support for C-V2X (PC5) and DSDA functions.

RN91xx provides a smart solution which enables automotive OEMs and Tier 1 suppliers to build a Linux-based connectivity and telematics control unit using a single module. Delivering up to 2.4Gbps download throughput, it comes with a dedicated application processor running an open-source Linux based platform (Legato).

It includes an MF-GNSS receiver, a C-V2X modem, security features and reduces system complexity with its established automotive-grade certifications, quality processes, and tolerance to extreme operating environments and temperatures.
