How it works
A distribution server provides a signed update package; the device downloads it, verifies authenticity and integrity, installs it (often in an A/B scheme or with a backup) and, on failure, reverts to the previous version. The process integrates with fleet management and telemetry.
Problem solved
Deployed devices still need bug fixes, security patches and new features, yet physically servicing a mass fleet is impractical and costly.
