iBeacon, the evolving technology that harnesses the advantage of Bluetooth Low Energy (BLE) to provide location based mobile application services to iOS powered devices, iPhone, iPad, iPad mini and iPod Touch. A beacon is a Bluetooth transmitter which can be placed anywhere remotely.
Applications installed on an iOS device will look out for this signal and will receive or send information. iBeacon however is in its developmental stages. The real-world application and possibilities are still being tested. Indoor shopping and deal alerts are expected to be the two areas in which the iBeacon concept could work out well.
