“5G Is Coming, and It’s Fortified With Fiber: Countless new wireless transmitters will relay all that data to your phone, and many will connect to the internet through endless miles of new fiber-optic cable.”

The next generation of wireless tech, 5G, promises a frictionless future: We’ll be able to do whatever we do on our phones much, much faster, and more devices can come online without slowing down the works. Self-driving cars, smart meters that track electricity usage, and health-monitoring devices may all take a big leap from childhood to adolescence.
5G will happen in the airy realm of radio waves. To get there, big telecoms have to harness underused parts of the spectrum. But there’s another crucial part underlying this system: lowly cable. Huge numbers of new transmitters will be needed to relay all that data to your phone, and many of those transmitters will still connect to the internet through fiber-optic cable—glass as thin as strands of hair carrying pulses of light.
