CEVA 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 (Find My), 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 by Apple in the Find My asset tracking service, the launch of the Apple AirTags, and the announcement by Google and many smartphone brands that they will soon be introducing similar options for Android devices.
Aimed at lowering the entry barrier and accelerating time-to-market for semiconductor and brands 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 the manufacturer’s own RF technology or with CEVA partners’ RF IP. Furthermore, the 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 to design products that leverage both standards.
"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,” says Ange Aznar, Vice President and General Manager of the Wireless IoT Business Unit at CEVA.
Solution from CEVA are available as a standalone UWB IP or in combination with RivieraWaves Bluetooth platform IP. CEVA’s RivieraWaves UWB platform IP is part of the wider Location Solutions portfolio of CEVA, spanning Wi-Fi (for Access Point scanning), Bluetooth (for AoA/AoD and HADM location), Dragonfly-GNSS (for GNSS snapshot positioning for Cellular-IoT/LPWA), VSLAM (for camera based localization), and MotionEngine Scout (for IMU based dead reckoning).
RivieraWaves UWB is available for licensing now.
