From manufacturing plants to animal tracking, accurate and reliable location data is transforming industries worldwide. Pozyx is a Belgian company specializing in ultra-wideband (UWB) and Bluetooth real-time location systems (RTLS). It delivers precise positioning solutions that are trusted by leading manufacturers and logistics operators. At the time of writing, Pozyx has over 150,000 active trackers in the field, powering real-time location data for thousands of assets across industries. To operate at this scale, battery life, industrial robustness, and development efficiency are critical, and STMicroelectronics components play an important role in achieving these goals.
Tags and Anchors: The Building Blocks of RTLS
In a Pozyx RTLS deployment, tags are small, battery-powered devices attached to assets, equipment, people, or even animals. They communicate with fixed anchors, which are strategically placed in the environment to calculate positions with centimeter-level accuracy. Together, they form the backbone of the Pozyx positioning system. These two device types have very different requirements. Tags must be compact and energy efficient, while anchors must deliver high performance and reliability to handle multiple communication protocols such UWB and BLE in real-time.
Ultra-Low Power Tags
Pozyx RTLS tags are designed to be lightweight, unobtrusive, and extremely energy efficient. Whether tracking equipment in a factory, pallets in a warehouse, or animals in the field, battery life is a top priority, especially when managing tens of thousands of deployed devices. The ultra-low-power accelerometers from ST, for example, consume only around 1 µA while active, allowing Pozyx to monitor motion continuously without significantly impacting battery life. This enables smart positioning logic: the tag can detect when an asset starts moving and automatically increase its update rate, while remaining in deep sleep when stationary. Combined with the STM32L0 series microcontroller, optimized for ultra-low energy consumption, Pozyx tags achieve multi-year battery lifetimes without compromising on accuracy or sensor integration.
High-Performance Anchors
While tags prioritize efficiency, anchors are designed for performance. Anchors handle UWB and BLE signal processing, precise timing synchronization, and communication between multiple tags to deliver centimeter-level accuracy at scale. Pozyx anchors leverage STM32F4 series microcontrollers to provide the necessary processing power for real-time ranging calculations, ensuring stable and reliable performance even in industrial environments. Combined with robust ST power management components, the anchors are built to withstand challenging conditions on the factory floor.
Another critical factor for Pozyx and its integration partners in industry and agriculture is long-term availability of components. Anchors are often deployed as part of larger integrated systems that need to remain operational for many years. By choosing ST components with long product lifecycles, Pozyx ensures that partners can reliably source the same parts well into the future, avoiding costly redesigns and ensuring hardware stability across deployments.
