But whether or not technological and commercial realities will reward that faith remains unclear. As with 5G smartphones, the basic challenge here sits at the intersection of the electromagnetic spectrum and telecom infrastructure economics.

When delivered over millimeter-wave frequencies and their copious amounts of free spectrum, 5G can match the speed and latency of fiber-optic broadband, with downloads of 1 gigabit per second and ping times under 10 milliseconds. But on those frequencies of 24GHz and up, signals struggle to reach more than a thousand feet outdoors.
