Away from the excitement about the long-awaited outcome of the 600 MHz band, there is actually far more disruptive potential in higher frequency spectrum, from the newly opened 3.5 GHz band to the emerging options in millimeter wave airwaves. Operators, whether established MNOs or would-be challengers, know they will need dense networks to support the capacity and ubiquitous coverage required for many key emerging applications like connected vehicles or smart cities. That means high capacity bands above 2 GHz will increasingly have more value than the former ‘beachfront’ airwaves below 1 GHz. But the rules for the higher bands are unclear, and may put swords in the hands of disruptors to far greater effect than the 600 MHz auction. Cable/WiFi…
