How can Rail Harness a More Powerful Internet?

5G is the next generation of mobile networks, following on from the current 4G technology. It will use a combination of frequency spectrum bands: low-band 600-Megahertz (MHz) spectrum for reliable national coverage, mid-band 3.5 Gigahertz (GHz) spectrum for reliable capacity and consistency, and 28 GHz millimetre wave (mmWave) spectrum for high-performance cases, including hotspots. 5G New Radio (NR) is a new air interface for 5G.
