5G will be a major upgrade to cellular networks. But since this technology requires more cell towers than 4G, it will make location tracking more precise (paywall).
5G signals in the U.S. will have a very short range and won’t easily go through buildings. This means there need to be many more cell towers. The main way that a cellphone tells where you are—as opposed to a website or an app—is, which tower are you talking to. Today’s towers have a radius of about a mile. If the new towers cover a much smaller area, it means that they know much more precisely where you are.
