IoT and connectivity engineering

Secure OTA updates

Over-the-air updates are the only practical way to fix vulnerabilities in devices already in the field. We design update mechanisms with signed images, verification on the device and safe rollback after a failed install.

Security architecture and the CRA support-period requirement are covered in cybersecurity & CRA and secure boot and OTA.

Low-power design

• Sleep modes and wake-up sources designed with the hardware team
• Radio duty cycles and data batching matched to the battery budget
• Current measurements on real hardware, not estimates only

Case

Maritime

Reliable sensor data from vessels with intermittent connectivity

Problem

Sensor data on board had to reach shore-side systems even when the vessel's link was unavailable for long periods.

What we did

Acquisition firmware with local buffering and a store-and-forward transmission layer.

Result

Data collected continuously and delivered when connectivity returned.

Maritime

Monitoring on-board infrastructure to plan maintenance before failures

Problem

Failures of on-board equipment were discovered only after they affected operations.

What we did

Health-data collection on board and analysis that flags degrading components.

Result

Maintenance can be planned from data instead of reacting to failures.

Critical infrastructure

Remote reading and control of water pumps

Problem

Pump stations had to be checked and adjusted on site.

What we did

Integration of pump controllers with remote reading and control over industrial protocols.

Result

Operators read status and control pumps remotely.
