Secure Cloud LTE-M, NB-IoT and EGPRS module with integrated M8 GNSS receiver for multiregional use
- Software‑based configurability within each hardware design
- Guaranteed best coverage with 23dBm output power
- Future‑proof solutions via uFOTA
The SARA‑R4 series modules are ideal for mission‑critical IoT solutions, as they include a unique and immutable root‑of‑trust. This provides the foundation for a trusted set of advanced security functionalities. The scalable, pre‑shared key management system offers best‑in‑class data encryption and decryption, both on‑device as well as from device‑to‑cloud. Utilizing the latest (D)TLS stack and cipher suites with hardware‑based crypto acceleration provides robust, efficient and protected communication.
Customers can future‑proof their solutions by means of the uFOTA client/server firmware updates, which utilizes LWM2M, a light and compact protocol ideal for IoT applications. Customized objects and resources can be created and added to devices that are already commercially in the field via the LWM2M dynamically loaded objects functionality.
The ultra‑compact 16 x 26 mm LGA modules offer the ability to make software‑based configuration decisions for LTE bands, radio interface and system selection preference, as well as Mobile Network Operator within each hardware variant.
With many interface options and an integrated IP stack, the SARA‑R4 modules are targeted to a wide range of data‑centric IoT applications, such as smart metering, smart lighting, telematics, asset tracking, remote monitoring, alarm panels, and connected health. The SARA‑R4 modules target long life, low‑maintenance, cost‑sensitive, lower power consumption, extended battery life applications.
Thanks to the u‑blox nested design principle SARA modules are compatible with other u‑blox product families, enabling easy migration from 2G, 3G and 4G. This maximizes the investments of customers, simplifies logistics, and enables very short time‑to‑market.
