5G is the talk of Las Vegas as CES 2019 again. This year, however, 5G's high-speed wireless networks are actually within eyeshot. Last year, Verizon launched its (sort of) 5G-based home broadband service and AT&T already rolled out 5G service in select markets. More cities will get 5G this year. The technology promises massive speed boosts -- think of downloading a season of Game of Thrones onto your phone in minutes -- as well as the potential for new developments, like streaming augmented reality.

Meanwhile, cable companies, which are stuck with physical connections, don't want to get left out of the 5G excitement. That's even if their G isn't the G that everyone is talking about.
