The year 2023 is showing some signs of being a watershed for 5G in millimeter wave spectrum, marking the tipping point from early optimism with mainly small-scale deployments, to an era of relatively widespread deployment to relieve capacity constraints and ultimately usher in new applications. The year has begun with a note of optimism as Mexico announced it would make up to 7,750 MHz of mmWave spectrum available to operators for 5G deployments during 2023. This comes as several emerging economies are looking to mmWave to help 5G reduce their historical broadband deficit, even if the improvements are patchy at first. This comes at a time of significant differences between developed mobile economies over their attitude to mmWave, with Japan…
