Bluetooth beacons are hardware transmitters — a class of Bluetooth Low Energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones , tablets and other devices to perform actions when in close proximity to a beacon.
Smartphone detecting an iBeacon transmitter. iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013. [1] Various vendors have since made iBeacon-compatible hardware transmitters – typically called beacons – a class of Bluetooth Low Energy (BLE) devices that broadcast their identifier to nearby portable electronic devices.
Most beacons use bluetooth technology to communicate with other devices and retrieve the location information. Apart from bluetooth technology however, several other location technologies exist. Apart from bluetooth technology however, several other location technologies exist.
Key finders with BLE beacon technology primarily aid in locating personal items. The beacon attached to an item like keys emits signals that, when in range, are detected by a smartphone app, indicating the item's location. BLE beacons transmit signals that are detected by a compatible device, enabling the device to determine the beacon's location.
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart [1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) [2] aimed at novel applications in the healthcare, fitness, beacons, [3] security, and home entertainment industries.

A large variety of techniques and devices are used to provide indoor positioning ranging from reconfigured devices already deployed such as smartphones, WiFi and Bluetooth antennas, digital cameras, and clocks; to purpose built installations with relays and beacons strategically placed throughout a defined space. Lights, radio waves, magnetic ...

Importantly, beacons do not generally accept connections from other devices, meaning that the beacon itself cannot record what devices are in its vicinity. In many cases, the simplicity of the beacon frame means that an app (for example Google Chrome ) is required in order to interpret the beacon's signal.
