– Ultra-low power RivieraWaves™ UWB platform IP targets mobile, automotive, consumer and IoT applications, lowering the entry barriers for companies to include UWB in their chip designs
– Industry-first combined IP offering of Bluetooth and UWB technologies is ideal for new use cases in emerging high-volume applications
CEVA, Inc., the leading licensor of wireless connectivity and smart sensing technologies, unveiled RivieraWaves™ UWB, an extremely power-efficient ultra-wideband (UWB) turnkey MAC and PHY platform intellectual property (IP) compliant with the IEEE 802.15.4z standard and in accordance with the FiRa consortium specifications. The RivieraWaves UWB platform IP delivers secure, centimeter-level accuracy and robust location information through Time-of-Flight (ToF) ranging and Angle-of-Arrival (AoA) processing. Extending CEVA’s market leading wireless connectivity IP portfolio for IoT devices, the new RivieraWaves UWB platform IP is ideal for a broad range of ultra-low power applications and products such as tags for pinpoint asset finding, secure digital key functionality for door locks, real-time location services (RTLS) and payment systems.

UWB is experiencing explosive growth fueled by its recent adoption in leading smartphone brands, with ABI Research forecasting annual shipments of nearly 1 billion devices by 2025. Aimed at lowering the entry barrier and accelerating time-to-market for semiconductor and IoT companies looking to develop UWB-enabled devices, the RivieraWaves UWB platform IP consists of a power-optimized hardware PHY along with a flexible, low latency hardware and software MAC layer. The MAC layer software can be implemented on the CEVA-BX1 DSP when deployed in combination with other connectivity workloads or modes such as direction finding, localization or radar, or as a standalone UWB MAC on commercial Arm and RISC-V MCUs. A flexible radio interface enables the RivieraWaves UWB platform IP to be deployed with customers’ own RF technology or with CEVA partners’ RF IP. Furthermore, RivieraWaves UWB platform IP is designed for ultra-low power use-cases, offering best-in-class performance and cost-efficiency, particularly when combined with RivieraWaves Bluetooth IP. This unique combined IP offering is an industry-first and addresses emerging applications and use cases that leverage both standards.
Ange Aznar, Vice President and General Manager of the Wireless IoT Business Unit at CEVA, commented: “Demand for UWB technology is at an all-time high, driven by emerging use cases in smartphones, accessories and other consumer and IoT devices. Our new RivieraWaves UWB platform IP addresses this burgeoning market by offering a licensable solution that lowers the entry barrier for companies looking to leverage this technology in their chip designs. As the only company capable of providing a combined UWB and Bluetooth licensable product, we have extended our industry-leadership position as the world’s foremost developer and licensor of wireless connectivity IP.”
