My understanding is they use bluetooth for coarse positioning (e.g. you're within 30 feet) then they use a special chip (ultra-wide band) for the precision location (within a foot or two).
Of course, there's a good bit of magic within all of that to make it work seamlessly.

Sounds to me like it is not a difficult problem except for the fact that they want to make it work with existing smartphones (both iOS and Android).
