Firmware Over the Air (FOTA) Testing for Connected Vehicles
A global engineering firm needed to guarantee FOTA campaigns would succeed across an OEM's fleet of more than one million connected vehicles. Here's how they validated the FOTA subsystem end to end, without relying on field tests alone.

A walkthrough of how the FOTA subsystem was virtualized, simulated, and validated at fleet scale.
Rolling out FOTA campaigns with no room for failure at fleet scale
The client, a global engineering firm, was rearchitecting a solution for an OEM operating a fleet of more than one million connected vehicles. Four realities made FOTA validation especially demanding.
Massive fleet scale
FOTA campaigns needed to succeed across an OEM's fleet of more than one million connected vehicles.
Full customer-base execution
The challenge was ensuring FOTA campaigns executed successfully across the entire customer base.
Device and software variety
The rollout needed to support many device variants and software layers.
Zero tolerance for failure
A failed FOTA campaign carries significant financial and business risk, so ensuring 100% reliability was critical.
From limited field access to unlimited virtual test scenarios
- −Low or no access to all hardware variants
- −Needed to prepare each variant for different software versions across every layer
- −Created scenarios in the test bench for power cycles and storage conditions
- −Network testing was only possible through field tests
- −Testing at scale was not possible
- −Test repeatability and consistency were below par
- ✓Rapidly created virtual models of the device variants with actual device applications running on them
- ✓Defined unlimited test scenarios by varying device conditions along with network and scale
- ✓Gained access to a comprehensive test bed to rigorously validate the FOTA subsystem
- ✓Achieved faster test cycles and lower cost of quality
