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.
iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013. 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.
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
The majority of beacon location devices rely on Bluetooth low energy (BLE) technology. Compared to 'classic' Bluetooth technology, BLE consumes less power, has a lower range, and transmits less data. BLE is designed for periodic transfers of very small amounts of data.
The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies. This article gives an overview of the core protocols and those adopted protocols that are widely used.
Nearby Messages is the API that can be used off of this protocol to receive data that is stored within beacons. Differing from iBeacon, Google beacons use not only Bluetooth but also WiFi and near ultrasonic sounds to communicate between devices.
A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. It resides on top of the Bluetooth Core Specification and (optionally) additional protocols.
Zigbee is an IEEE 802.15.4 -based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
Bluetooth is defined as a layer protocol architecture consisting of core protocols, cable replacement protocols, telephony control protocols, and adopted protocols. Mandatory protocols for all Bluetooth stacks are LMP, L2CAP and SDP.
The Facebook Bluetooth Beacon is a hardware beacon released by Facebook in 2015. The beacon uses a bluetooth connection to communicate with the Facebook app on the user's smartphone, informing it of the phone's location. The technology allows location-specific advertising to be pushed to the user's Facebook feed.
