5G is coming. Tech companies show they’re ready

This week at CES, the annual tech convention in Las Vegas was filled with demos highlighting the potential of next generation of internet speed.

5G could make the process of loading websites, downloading songs and streaming movies at least 10 times faster than 4G. It’s not expected to start replacing 4G in the United States until 2020, but companies such as Verizon, Sprint and AT&T — CNN’s parent company — aim to launch 5G smartphones this year.
