Nuremberg, Germany — Metirionic, a specialist in wireless positioning technologies, has unveiled what it calls a “transformative leap” in spatial awareness at this year’s Embedded World conference. The company demonstrated the first commercial implementation of high-precision distance and angle estimation using Bluetooth Channel Sounding—a capability previously confined to research labs. The breakthrough, achieved through its Metirionic Advanced Ranging Stack (MARS), enables simultaneous measurement of both range and bearing from a single Bluetooth procedure, marking a shift from basic proximity detection to full spatial context awareness.
The technology leverages quad-antenna arrays and advanced signal processing to isolate the direct RF path between devices while suppressing multipath interference—a persistent challenge in indoor environments. By analyzing Channel Impulse Response (CIR) data, MARS converts raw Bluetooth Phase and Channel Transfer (PCT) measurements into actionable positioning intelligence. This precision, the company claims, achieves sub-meter accuracy in real-world conditions, a threshold critical for applications demanding both security and reliability.
Metirionic’s demonstration at Embedded World featured four distinct use cases showcasing the versatility of its stack across hardware platforms. The most technically ambitious was a live distance-and-angle estimation demo using Nordic Semiconductor’s nRF54L15 chipset on an Ezurio module. The system employed a quad-antenna initiator paired with a dual-antenna reflector, with real-time spatial data visualized through Metirionic’s evaluation software. “This isn’t just about knowing *how far* someone is,” said Attila Romer, Managing Director of Metirionic. “It’s about understanding *where* they are in three-dimensional space—whether that’s which side of a door they’re on or how they’re moving through a room.”
Security applications dominated the demonstrations. A live secure access alarm system, built with Synaptics’ Veros WiFi/BT combo chipset and Astra IoT platform, highlighted the technology’s potential for smart homes. The initiator—an alarm panel equipped with MARS—processed signals locally to determine whether an approaching smartphone user should disarm the system, eliminating the need for manual input. “The decision-making happens at the edge,” Romer explained. “There’s no cloud dependency, no latency, and no vulnerability to spoofing attacks.”
Commercial readiness was emphasized through partnerships with hardware providers. Ezurio’s newly available nRF54L15 dual-antenna development kits, supported by Metirionic’s software stack, offer a 2x performance boost over single-antenna designs. The company also collaborated with Bauer Products to showcase a Bluetooth Channel Sounding door lock, developed with embedded software support from onceLabs. The lock, on display at Nordic Semiconductor’s and Zephyr’s exhibits, uses MARS to authenticate users based on spatial positioning rather than traditional credentials.
Protocol validation was another focus. Metirionic announced a partnership with Ellisys to demonstrate how the Bluetooth Vanguard analysis system captures raw PCT data, which is then transformed into precise positioning metrics. This integration is designed to accelerate product development for manufacturers by providing a lab-based validation pipeline. “We’re not just selling algorithms,” Romer said. “We’re providing the entire ecosystem—from chipset to application layer—that turns Channel Sounding from a theoretical capability into a deployable solution.”
The company’s approach to commercialization centers on three pillars: advanced positioning algorithms, evaluation software, and engineering services. By partnering with silicon suppliers (Nordic Semiconductor, Synaptics), module providers (Ezurio, Minew, Raytac, Fanstel), and antenna specialists, Metirionic positions itself as a one-stop solution for Bluetooth 6.x products requiring spatial awareness. The technology’s immediate applications span industrial asset tracking, smart building automation, and high-security access systems, where traditional Bluetooth LE solutions fall short.

At Embedded World, Metirionic’s booth in Hall 4, Stand 4-580, hosted interactive demonstrations alongside partner exhibits. Visitors could experience the technology firsthand, with technical experts available to discuss integration challenges and use cases. The company also emphasized its role in standardizing Bluetooth Channel Sounding, noting that its MARS stack is compatible with the Bluetooth SIG’s latest specifications while addressing real-world deployment hurdles.
While Metirionic’s announcement signals a major step forward for wireless positioning, industry observers note that widespread adoption will depend on hardware standardization and developer familiarity with Channel Sounding. The company’s focus on edge processing and local decision-making aligns with broader trends in IoT security, where minimizing cloud reliance is increasingly prioritized. For now, the technology remains at the demonstration stage, with commercial products expected to enter the market in phases over the next 12–18 months.
