the iBeacon standard doesn't include specific location information

I know almost nothing about iBeacons, other than reading that iPads can
use them for "micro-location"

they're not just for ipads, but any bluetooth le capable device,
including iphones and many (but not all) android devices.

ibeacons are mainly used to provide location information inside a
building, often used in museums, for self-directed guides or just to
find out more about whatever the visitor is looking at:

Utilizing iBeacon technology to automatically present visitors with
audio, video, and text related to the artworks and building features
nearest to them, Guggenheim Near Me offers a site-specific experience
for visitors as they move through the museum.

they're also used at airports, sports arenas, stores and many other
places.
