Build apps that interact with accessories simply by being in close proximity to an Apple UWB-enabled product. Taking advantage of UWB allows you to create more precise, directionally aware app experiences.
Use the Nearby Interaction accessory protocol and an MFi-certified UWB solution to manufacture accessories that interact with UWB-enabled Apple products.
Chipset vendors who are interested in enabling Apple UWB interoperability with their UWB solutions should become a member of the FiRa Consortium and join the MFi Program to access the necessary technical specifications and resources.
