RDK-B (Reference Design Kit for Broadband) devices run complex software stacks. Networking, media, security, device management. All built from open-source components that get integrated into a single firmware image. Each component might pass its own unit tests, but the full stack introduces interactions that individual testing doesn't catch. A Wi-Fi driver update might affect WAN failover behaviour. A security patch might change how TR-069 provisioning works. These cross-component issues are where the real bugs live, and they only show up when you test the system as a whole.
We validate RDK-B builds end-to-end. Functional testing across WAN, LAN, Wi-Fi, and management interfaces. Performance testing under realistic traffic loads with multiple streams, mixed protocols, and concurrent clients. Compliance testing against the operator acceptance criteria that your cable or broadband partner actually uses for deployment approval.
We also test firmware upgrade and rollback procedures, factory reset behaviour, and long-duration stability (soak testing) because the problems that show up after 72 hours of runtime are the ones that cause truck rolls. If you're shipping a broadband gateway, set-top box, or any RDK-B powered device, we make sure it works the way your operator expects. Not just the way your spec says it should.
