The Ceva-Waves UWB platform includes hardware IP for an optimized UWB MAC and PHY meeting 802.15.4 HRP, FiRa 3.0, and the Car Connectivity Consortium Digital Key 3.0 (CCC DK3.0) requirements. The platform includes advanced Wi-Fi interference suppression.

A comprehensive suite of CPU-agnostic software stacks that support FiRa 3.0 MAC, CCC DK3.0 MAC, and radar for implementing applications such as automotive digital keys and in-cabin child-presence detection (CPD), general power-saving presence detection in laptops, TVs and smart buildings, asset tracking tags, real-time location services (RTLS), and tap-free payment.

With proven MAC and PHY hardware IP and a wide range of application software, the Ceva-Waves UWB platform provides a fast, reliable route to FiRa and CCC UWB functionality in an SoC, separately or in conjunction with Ceva-Waves Bluetooth. In the latter configuration, operation of the two platforms can be orchestrated to minimize power consumption over long operating periods. The platform complies with major standards such as FiRa 2.0 and CCC DK 3.0. An optimized hardware and software architecture assures precise and robust location and radar data sufficient to detect human respiration remotely even in the presence of complex multipath environments and strong Wi-Fi signals.
