FiRa Core Certification program 4.0 – A flexible path to interoperability

FiRa’s Core Certification Program is modular, which allows devices to select specific features individually for certification. FiRa’s Core Certification Program 4.0 release adds UL-TDoA and the full scope for Aliro UWB features to the certification program.

“FiRa’s Core 4.0 release underscores our commitment to advancing interoperability in FiRa technology,” said SK Yong, the board chair of the FiRa Consortium. “By expanding certification coverage to include UL-TDoA and Aliro UWB features, we’re ensuring that products across the ecosystem can interoperate seamlessly and deliver consistent performance.”

The Core Certification Program 4.0 assures interoperability of FiRa-enabled devices, driving adoption and innovation across industries. Its rollout covering PHY, MAC, Link Layers and Interoperability testing further solidifies FiRa’s position within the IoT ecosystem.

FiRa Core 4.0 Specifications and Certification Program are available to FiRa Consortium members; non-members can purchase specifications. For more information about becoming a FiRa member, visit: https://www.firaconsortium.org/membership.
