A single beacon can transmit one, two or all three frametypes. The three frametypes are: Beacon protocol - Google's Eddystone. URL: a URL (i.e. a website link) is transmitted to the device, eliminating the need for an installed Mobile App. UID (similar to Apple's UUID): a 16 digit string of characters, which can identify the individual beacon.
One use of beacons is as a "key finder" where a beacon is attached to, for example, a keyring and a smartphone app can be used to track the last time the device came in range. Another similar use is to track pets, objects (e.g. baggage) or people. The precision and range of BLE doesn't match GPS, but beacons are significantly less expensive.
Non-directional beacons in North America are classified by power output: "low" power rating is less than 50 watts; "medium" from 50 W to 2,000 W; and "high" at more than 2,000 W. [3] There are four types of non-directional beacons in the aeronautical navigation service: [4] En route NDBs, used to mark airways; Approach NDBs; Localizer beacons
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.

An amateur radio propagation beacon is a radio beacon, whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and ...
