iBeacons is a new core Location feature iOS 7 that allows your iPhone or iPad with a Bluetooth 4.0 chip (also known as Bluetooth Low Energy, or BLE) in it to know where it is in relation to other BLE devices. iBeacons allows devices to talk to each other, relating their location in real time without the need for Wi-Fi or GPS. Apple introduced iBeacon as part of iOS 7 , though it mentioned the feature only in a single keynote slide and didn’t go into detail at all. But this hasn’t stopped companies from taking advantage and launching products and services that make use of iBeacon.
