So it's nothing to do with GPS then? So why is this in the title?

  Agreed, the title is very misleading.

  Perhaps the author thinks "GPS" refers to the general problem of tracking location, rather than a specific system that solves that problem?

  Yes, the title is wrong. Maybe "How smartphones can track you, even when you turn GPS off"? But also, these researchers apparently didn't have access to cell-tower location data. Or at least, it's not mentioned in the article.

  Doubt the author - and most laypeople - understand how GPS works.
