What is an iBeacon and Bluetooth LE (BLE)?
iBeacon are small, low power computers comprised of a CPU, battery, flash memory and Bluetooth LE. They have long battery life – most Beacons available have an advertised battery life of 12-24 months – making it easy to install them anywhere (no plugs needed) and easy to maintain. The broadcast range can be set between a few inches and 50+ meters. An iBeacon is too small to hold data itself – so it reaches out to the cloud or other servers to pull content down to push out to the device.
