Columbia University's Steve Bellovin sat down with The Wall Street Journal to discuss the potential privacy issues related to 5G networks. Since 5G signals in the U.S. will have a shorter range, Bellovin said, more cell towers will need to be erected. Bellovin believes this gives companies the ability to collect more precise location data, and since 5G cannot go through walls, the computer science professor said towers will be placed inside buildings for even more accurate location information. "We need much clearer regulation of what carriers can do with location data," Bellovin said. (Registration may be required to access this story.)
