The quest for ubiquitous 5G coverage has encountered formidable challenges, especially with millimeter-wave technology, which offers the tantalizing promise of blistering speeds and expansive network capacity. However, the practical rollout has been beset by low signal-to-noise ratios and link blockage—hindrances primarily due to the high-frequency signal’s vulnerability to obstruction. But there’s a new cause for optimism; Tokyo’s renowned technology research
