Fading in reflective and heavily shadowed industrial environments with large arrays

Sara Willhammar, Liesbet Van der Perre, Fredrik Tufvesson

One of the use cases for 5G systems and beyond is ultra-reliability low-latency communication (URLLC). An enabling technology for URLLC is massive multiple-input multiple-output (M…
