The combination of Metirionic’s Advanced Ranging Stack (MARS) and Nordic’s nRF54L15 facilitates innovative solutions for distance ranging and location tracking.
NUREMBERG, Germany, March 10, 2025 — Metirionic GmbH, a leading innovator in wireless ranging and positioning technologies, is excited to announce the launch of its Bluetooth® Channel Sounding Evaluation Kit for the Nordic nRF54L15 (DMK-54L) at Embedded World 2025. This integrated platform enables secure, high-precision distance measurements and real-time location services (RTLS) within the Bluetooth ecosystem.
This platform provides innovative product developers with access to an ultra-low-power, cost-effective multiprotocol radio that features an integrated MCU, 1.5 MB of NVM, and 256 KB of RAM. It also includes an advanced, high-performing distance ranging solution that mitigates multipath effects, delivering real-time distance estimation with accuracy up to 10cm. This solution, Metirionic’s Advanced Ranging Stack (MARS), 
surpasses traditional Phase-Based Ranging (PBR) and Round-Trip Time (RTT) methods, unlocking the full potential of Bluetooth Channel Sounding. Metirionic also offers engineering services to customize MARS to specific customer requirements.
“Metirionic’s MARS and the nRF54L15 offer an excellent solution for customers seeking both flexibility and performance in Bluetooth Channel Sounding,” stated Paal Kastnes, Nordic Technical Product Manager. “The nRF54L15 is tailored for next-generation Bluetooth LE products, providing high-performance communication and secure fine-ranging to drive the advancement of IoT applications.”
MARS, a sophisticated low-power signal processing software layer, operates seamlessly on Nordic’s nRF54L15 embedded MCU, an external MCU or processor, or a host PC. It ensures precise, reliable, and real-time ranging and location accuracy for applications in industrial settings, IoT, RTLS, logistics, and secure access. Metirionic’s decade-long pioneering efforts have ensured that MARS is designed to meet the evolving demands of modern industries, whether it’s optimizing asset tracking in warehouses, enabling precise keyless entry, or ensuring accurate navigation for automated guided vehicles.
While useful, RTT is highly susceptible to multipath interference, leading to significant outliers that reduce accuracy. PBR improves upon RTT but faces challenges in reflective environments. MARS offers a superior alternative by utilizing the complete Channel Impulse Response (CIR) for highly accurate and reliable distance estimation, while minimizing hardware resources and power consumption. MARS supports large-scale deployments and is designed to adapt to future Bluetooth developments, ensuring both scalability and longevity.
“Our integration with nRF54L15 represents a crucial step in making advanced Bluetooth ranging technology more accessible,” commented Dr. Attila Römer, Managing Director of Metirionic. “With the new evaluation kit and our engineering services, we empower developers to fully utilize Bluetooth Channel Sounding, enabling applications requiring precise distance estimation and robust RTLS performance.”
The DMK-54L Evaluation Kit allows developers to explore MARS capabilities in real-world scenarios, enabling precise distance measurements and system performance evaluations across diverse environments. It unlocks the potential of Channel Sounding in their products and serves as a powerful tool for testing, validating, and enabling high-accuracy ranging applications. The DMK-54L is currently available for purchase via email at , and a product brief highlighting key performance benchmarks is available for download .
