Lower latency could help 5G deliver mobile networks that let us do entirely new things, not just modestly improve what we're already doing now. Possibilities include multiplayer mobile gaming, factory robots, self-driving cars and other tasks demanding quick response -- all areas where today's 4G networks struggle or can't manage at all.

"Latency is really going to open up new real-time experiences we've never had before," said AT&T Chief Technology Officer Andre Feutsch.
