How Avnet Silica Enables Secure IoT with eSIM and Ultra-Wideband Precision Tracking

At Embedded World 2025, Electropages caught up with Walter Puhl from Avnet Silica to explore two cutting-edge demos: eSIM-based remote connectivity and ultra-wideband (UWB) location tracking. Walter explains how Avnet Silica’s 5G solutions allow for seamless over-the-air provider switching using eSIM technology — a game-changer for global IoT deployments. No more swapping physical SIM cards or sending engineers into the field. 

The second demo highlights ultra-wideband modules from Qorvo, delivering centimetre-level accuracy in real-time location tracking. From asset monitoring in logistics and manufacturing to high-security applications like automotive access and hospital equipment tracking, UWB is opening new possibilities for precise, low-latency localisation.
