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.
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 ...
Compared to devices based on Global Positioning System (GPS), beacons provide more accurate location information and can be used for indoor location. Various types of beacons exist, which can be classified based on their type of Beacon protocol, power source and location technology.
Bluetooth Low Energy beacon; E. Emergency locator beacon; Emergency position-indicating radiobeacon; G. ... Wi-Fi positioning system
Bluetooth based beacons periodically send out a data packet and this could be used by software to identify the beacon location. This is typically used by indoor navigation and positioning applications.
Navizon, Inc. is a provider of location-based services and products. Navizon was an early developer of technology that makes it possible to determine the geographic position of a mobile device using as reference the location of cell phone towers and Wi-Fi-based wireless access points instead of GPS.
Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]
