u-blox's global LPWA cellular modules gain security and positioning features

The new u-blox SARA-R4 series offers best-in-class security as well as
integrated u-blox GNSS technology.

Thalwil, Switzerland - February 24, 2020 - u-blox (SIX:UBXN; OTC:UBLXF), a
global provider of leading positioning and wireless communication
technologies, has 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 new SARA-R422 product series offers superior security protection,
industrial output power to grant best coverage even in weak signal
conditions, and everywhere location using state-of-the-art u-blox GNSS
technology", says Rado Sustersic, Senior Product Manager, Product Center
Cellular at u‑blox. "These represent valuable functionalities tailored
specifically to the LPWA IoT market."

The SARA-R4 series is ideal for a wide range of 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.

Best-in-class foundation and end-to-end security:
Security features include a unique and immutable root of trust (RoT) for
each device, as well as access to a scalable pre-shared key (PSK) management
system. This provides the foundation for a trusted set of advanced security
functionalities to enable data encryption and decryption, both on-device as
well as from-device-to-cloud. The choice of PSK based security, rather than
the more complex and computationally intensive public key infrastructure
(PKI) approach, strikes the right balance between implementation costs and
level of security protection for many IoT applications.

Guaranteed best coverage with 23 dBm output power:
All SARA-R422 modules provide 23 dBm output power, allowing the end device
to properly operate in all network conditions. This means no issues at cell
edges, no coverage issues in weak signal conditions, and, even more
importantly, no unwanted re-transmission that shortens battery life by
increasing transmit time and overall system power consumption.

Everywhere location via integrated u-blox technology:
The SARA-R422M8S is pre-integrated with the u-blox M8 GNSS (global
navigation satellite system) receiver and a separate GNSS antenna interface.
This uniquely provides highly reliable, accurate 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(R) service,
ensuring that location data is always available everywhere.

"Furthermore," says Rado Sustersic, "the series is designed for long working
lifetimes in the field, through the inclusion of support for LWM2M, a
lightweight machine-to-machine communications protocol ideal for IoT
applications with the possibility of updating the firmware of modules
already in the field over the air via the uFOTA (Firmware Over The Air)
client/server firmware service provided by u-blox".

The u-blox SARA-R4 series will be presented at the upcoming Embedded World
Nuremberg, Germany (February 25-27, 2020; Hall 3/Stand 3-139).
