Glossary & FAQs

AltBeacon: Radius Networks’ proposal for an open and interoperable specification for proximity beacons.

Beacon: any device that transmits a signal (BLE signal) which allows another device to determine its proximity to the beacon (broadcaster). Main function of a beacon = one way broadcast.

Beacon enabled: refers to the capability of a device to ‘listen’  for beacon hardware.

Beacon SDK: SDK means Software Development Kit. The code libraries developers use in their apps in order to scan, get proximity values or broadcast as a beacon.

BLE: Bluetooth Low Energy (BLE) is the power-and application-friendly version of Bluetooth that was built for the Internet of Things (IoT).

Broadcaster: usually a physical beacon device, such as GemTot or others. Although smartphones, tablets or computers could be programmed to broadcast-only.

Broadcaster / Scanner: device that is simultaneously scanning and broadcasting

Eddystone: Open Bluetooth 4.0 protocol from Google. Eddystone is an open protocol; specification is available for everyone.

Eddystone specification:

  • Eddystone-URL:  contains a single field: URL. The size of the field depends on the length of the URL.
  • Eddystone-UID: Eddystone-UID contains an identifier of a beacon.
  • Eddystone-TLM (telemetry packet): Eddystone-TLM packet is designed to be broadcast by the beacon alongside the “data”  (i.e., UID and/or URL) for the purposes of fleet management.

GemTot  App:  this utility app allows owners of GemTot Bluetooth beacons to easily:

  • Configure GemTot Beacons
  • Simulate in-app user experiences based on different proximities to a beacon
  • Demo to clients how beacons work with apps through lockscreen notifications & full screen content
  • Show the relative distance to a beacon

GemTot Beacons: is a USB device that broadcasts signals that can be heard by smart devices nearby. Paired with an app or a Passbook pass, businesses are able to deliver contextually relevant content and information to users at very specific locations.

iBeacon: Apple’s trademark that referee to the protocols, devices, and uses of Bluetooth LE to create user experiences.

IoT: Internet of Things, the network of physical objects embedded with electronics, that enables these objects to collect and exchange data.

Major: specifies a particular beacon within a group.

Minor: groups a related set of beacons.

Physical Web: Google’s discovery service powered by bluetooth low energy beacons.

Physical Web URLs: Smart objects broadcast these URLs that any nearby device can receive

Scanner: any device that can scan for beacons and detect how far they are. Usually thought of as a smartphone, but it can be any computing device with bluetooth.

Telemetry data: Eddystone beacons may transmit data about their own operation to clients. This data is called telemetry and is useful for monitoring the health and operation of a fleet of beacons.

UUID: Universal Unique Identifier – the identifier that distinguishes your beacon from others

WeChat Beacons: the only beacon that can simultaneously broadcast two iBeacon signals alongside an Eddystone signal. Allowing businesses to broadcast simultaneously to both WeChat users, iPhone users, as well as supporting contextual Eddystone attachments, Physical Web URLs and telemetry data.
