u-blox extended its SARA-R4 family of LTE-M / NB-IoT and EGPRS cellular modules to include variants with the hardware and software features necessary to enable end-to-end security features and services for Internet of Things (IoT) data, devices, and ecosystems.

The series focus on mission-critical IoT solutions such as connected healthcare, industrial monitoring, point of sale and vending terminals, tracking and telematics devices, as well as smart lighting solutions and building automation.

Security features include root of trust (RoT) for each device, as well as access to a scalable pre-shared key (PSK) management system. The choice of PSK based security, rather than public key infrastructure (PKI) approach, was chosen to create a balance between implementation costs and level of security protection for many IoT applications.

The SARA-R422 modules provide 23 dBm output power.

Additionally, SARA-R422M8S is pre-integrated with the u-blox M8 GNSS (global navigation satellite system) receiver and a separate GNSS antenna interface. This allows for positioning data simultaneously with LTE communications. The module also supports hybrid positioning strategies, in which positioning data provided by satellite constellations is enhanced with data from the u-blox CellLocate service.
