CEVA‘s Hybrid Wireless IP technology provides design engineers with high-precision, low-latency proximity sensing and access control for next-generation products. This hybrid IP offering simplifies the integration of centimetre-level accuracy with secure, real-time connectivity across automotive, industrial, and consumer systems.
At the heart of CEVA’s solution is its ultra-wideband (UWB) IP, which delivers FIRA 3.0-compliant distance measurement with sub-centimetre precision. This enables seamless and secure applications like digital key access, proximity-based locking, and spatial awareness across a wide range of devices. UWB’s strength lies in its accuracy, but CEVA has ensured that it also meets industrial-grade security standards—making it ideal for automotive keyless entry, industrial authentication, and enterprise-grade device locking.
Complementing this, CEVA’s Bluetooth 5.3 IP supports channel sounding for proximity detection without requiring heavy infrastructure or complex processing. This addition allows developers to integrate secure Bluetooth and ultra-wideband ranging using one IP source while optimising for cost and power where UWB is overkill. For example, Bluetooth’s role in CEVA’s demos included screen lock automation based on device distance—showing how the same IP can serve both consumer and enterprise markets.
The real power of CEVA’s Hybrid Wireless IP is in the hybridisation. Combining Bluetooth and UWB allows systems to balance precision and efficiency. Bluetooth handles continuous presence detection with minimal power, while UWB triggers secure unlock or higher-level actions. This two-tier approach to proximity sensing enables more reliable, secure, and battery-conscious experiences.
For design engineers, integrating CEVA’s Hybrid Wireless IP is supported by a rich development ecosystem. Developers gain access to IP cores, software stacks, and hardware abstraction layers that allow them to deploy across mobile, automotive, and IoT hardware targets. Whether you’re aiming for millimetre-accurate positioning or passive proximity detection, CEVA’s platform covers both ends of the spectrum.
CEVA’s Hybrid Wireless IP is a compelling proposition for engineers building access control, localisation, and context-aware embedded devices. With proven demos, FIRA-compliance, and silicon-ready IP, CEVA helps engineers reduce complexity while elevating capability.
