5G promises exceedingly fast download speeds and low latency, or lagginess, connecting to a data network. Beyond cell phone use, industries as wide-ranging as city planning, manufacturing and medicine will all be able to tap into 5G's enormous bandwidth to let machines almost instantly communicate with each other. Even getting off on the wrong foot, 5G's ascendancy as the 4G's eventual replacement is a fact, not a fad.

As wonderful as the 5G future sounds, the first stirrings of our 5G present was confusing, frustrating and disappointing as the lightning-fast speeds on some benchmarking tests failed to translate into real gains when downloading large app and video files. Verizon's first and right now only 5G phone, the Moto Z3 with 5G Moto Mod, also appeared unable to lock onto and maintain a 5G connection, flickering often to a 4G icon. And when the battery on the Moto Mod I was using completely drained, my 5G cut out too, without me even realizing it.
