Location information in a protocol only makes sense if it is associated
with some identifier. Thus, I don't think that general discussion about
the location of a cellphone vs. a person is sufficiently precise. It
makes sense to say "identifier X in protocol Y has location property Z,
where Y can be a location-specific protocol or a protocol whose primary
purpose is something other than conveying location. It's users who then
make associations with people, buses, taxis or other objects. We don't
have intrinsic identifiers for these objects, certainly not a single
one.
