Ultra-wideband (UWB) technology is undergoing one of the most significant transitions since it first appeared in consumer devices. Once known primarily for smartphone-centric “find my” functions, UWB has rapidly evolved into a sophisticated platform for secure access control, real-time location systems (RTLS), object tracking, and even low-power radar sensing on embedded endpoints. Standards such as FiRa 3.0 and Aliro promise broader interoperability across consumer and industrial ecosystems, opening doors to hands-free authentication, robust RTLS deployments, and context-aware automation.

This week’s New Tech Tuesdays breaks down the architectural advancements enabling modern endpoint UWB, traces the engineering milestones behind today’s secure ranging and radar functions, and examines the hardware innovations positioning UWB as a core spatial-sensing technology for next-generation embedded designs.

UWB’s evolution has been shaped by a combination of technological capability, security requirements, and ecosystem momentum. The earliest commercial UWB systems were limited to niche industrial environments and specialized RTLS deployments where accuracy outweighed cost and power constraints. The technology’s leap to mainstream relevance came only after it entered smartphones, establishing a globally installed base and proving its value for device-to-device localization.

Improvements in mixed-signal integration and radio frequency (RF) front-end design paved the way for UWB to serve as a short-range radar. Just as edge-optimized sensor systems have enabled real-time processing in applications like biometrics and industrial monitoring, UWB’s impulse-based signaling proved capable of detecting presence, micro-movement, and even basic vital-sign patterns at extremely low power. These advancements transformed UWB from a ranging technology into a multi-modal sensing platform.

The next several years will be pivotal as UWB expands from smartphones and vehicles into endpoints across homes, factories, and commercial environments.

The FiRa Core 3.0 standard, released with a stronger focus on multi-vendor interaction and secure ranging profiles, is expected to drive widespread adoption of UWB in enterprise access systems and smart buildings.^[1] Meanwhile, Aliro, an open standard developed by the Connectivity Standards Alliance (CSA) for interoperable digital keys, is being positioned to unify mobile, Internet of Things (IoT), and vehicle access experiences under a consistent, secure protocol.^[2]

Together, these standards will allow engineers to design access systems that work across devices and brands, reducing ecosystem fragmentation and enabling cross-industry deployment at scale.

Industrial environments will benefit from UWB endpoints with built-in 3D positioning capabilities, enabling simplified deployments and replacing costly multi-anchor systems. Autonomous mobile robots (AMRs), pallet tracking, and worker safety systems will increasingly rely on UWB for high-precision, low-latency spatial awareness.

Endpoint radar sensing is also emerging as a transformative capability for UWB. Devices with integrated radar processing will enable presence-aware lighting, energy-optimized HVAC control, gesture-responsive human-machine interfaces (HMIs), and health-monitoring functions without requiring cameras or complex computing hardware.

Because UWB radar offers better privacy than camera-based systems and consumes less power than mmWave, it’s emerging as a strong candidate for battery-operated devices and smart consumer products.

Developing endpoint UWB solutions traditionally required designers to combine discrete RF, processing, and security components, which proved challenging for low-power devices. The Qorvo QM35825 UWB low-power system-on-chip (SoC) simplifies this challenge by integrating the RF transceiver, computing subsystem, and security primitives into a single, compact device. Because the device incorporates its own processing subsystem, it can handle time-of-flight (ToF) ranging calculations, radar signal interpretation, and secure authentication logic without relying heavily on external computation resources.

The SoC’s security architecture supports authenticated ranging profiles aligned with FiRa-class applications, offering designers a reliable path toward interoperable, standards-compliant UWB products. Additionally, the device’s low-power design enables always-on sensing, making it well-suited for applications such as occupancy detection, asset tracking, and hands-free device interactions.

UWB is becoming a core technology for spatial computing, secure access, automation, and intelligent sensing at the endpoint level. As standards mature and highly integrated SoCs enter the market, engineers can build devices that combine precise ranging, robust security, and short-range radar in compact, low-power designs.
