SARA-N2 - Power-optimised NB-IoT (LTE Cat NB1) modules

The u-blox SARA-N2 is an NB-IoT modem in a compact LGA package, offering low standby and operational power consumption, with extended coverage.

The SARA-N2 series NB-IoT modules feature extremely low power consumption in both idle and connected modes of cellular operation. They are available in a small LGA form factor and have been designed explicitly with the needs of battery powered applications that need to communicate for long periods of time in challenging radio propagation conditions.

The modules support a comprehensive set of communication protocols with minimal signaling overhead to preserve power consumption. The feature set makes these modules ideally suited for applications where longevity of operation and reachability in poor propagation conditions are mission critical. Smart water metering, smart gas metering, smart sensors for remote monitoring and nomadic asset tracking are perfect examples of applications where these modules could be used.

The SARA-N2 series modules target high volume, cost sensitive applications, and provide "bit pipe" communication functionalities while minimizing the customer's total cost of ownership. The modules offer easy migration from u-blox GSM (SARA-G3 series), UMTS (SARA-U2 series), as well as LTE Cat 1 (LARA-R2 series) modules. The temperature range of -40 to +85 ° C guarantees operation in harsh environments and in very compact designs. The modules are for global use and will be certified and approved by the main regulatory bodies

Key features:

  • Ultra low power consumption delivering 10+ years battery life
  • Excellent extended range in buildings, underground (MCL 164 dB)
  • Extended temperature range of -40 to +85º C and ISO/TS16949 manufacturing
  • Easy migration between u‑blox 2G, 3G, and 4G modules
  • Very small SARA LGA form factor for easy manufacturing
