iBeacons works on BLE (Bluetooth Low Energy) technology launched by Apple with iOS7. Any device that broadcast the same frame to other devices on the network is called Beacon. iBeacon app development is developing many engagement options that are transforming the event industry. The technology used in the apps renders countless opportunities to upgrade the user experience. If the attendees did not register prior, or if the sponsors or the attendees did not meet prior, or whatever shortcomings come up at any event, venue, exhibition or any gathering; with iBeacon, all gaps can be filled to provide an event full of engagement and synchronicity.
