nRF9151 System-in-Package

Low power SiP with integrated LTE-M/NB-IoT and DECT NR+ modem, and GNSS

The nRF9151 sets a new standard for highly integrated and compact System-in-Package (SiP) solutions, specifically designed for cellular IoT and DECT NR+ applications. Leveraging low power LTE technology, advanced processing capabilities, and robust security features, the nRF9151 offers unparalleled performance and versatility, and supports 3GPP release 14 LTE-M/NB-IoT and DECT NR+. The nRF9151 will also add support for Non-Terrestrial Network (NTN) in a future firmware release.

Compared to its predecessor (nRF9161), it boasts a significant footprint reduction of 20% and brings additional support for Power Class 5 20 dBm.

Main Benefits

  • Enhanced Capabilities: The nRF9151 surpasses its predecessor with support for Power Class 5 20 dBm output power, complementing the existing Power Class 3 23 dBm, which provides great design flexibility as it eases the requirements for battery-powered products.
  • Global Connectivity and Power Efficiency: The integrated modem of the nRF9151 enables global connectivity without regional limitations, and include new unique modem features for further power saving and ease of use.
  • Unleashing the Potential of DECT NR+: Harness the capabilities of the DECT NR+ stack with the nRF9151, enabling massive mesh applications that prioritize reliability, secure connections, long range, and scalability.
