Apple Introduces iBeacons for Bluetooth LE Location

With iOS7, Apple introduced iBeacons, a Bluetooth Low Energy profile for micro location; support for low-cost iBeacons transmitters that can connect an iPhone to a range of devices over Bluetooth 4.0. The device would let the iPhone activate doors, lights and other things as a person holding it moves by.

This can mean iOS device may be able to use BT 4.0 devices to collect precise location data, i.e., location inside of a building—even though those devices don’t have a GPS system installed.
