Apple iBeacon Technology Overview

Слайд 1

Apple iBeacon Any BLE enabled device can act as an iBeacon iBeacon is a custom advertising packet for BLE devices that exposes several numbers: UUID, Major and Minor Passive technology – no connection needed Natively supported in iOS 7 Apple WWDC - June 2013

Слайд 2

iBeacon Advertisement Packet Structure iBeacon Preamble 02 # Number of bytes that follow in first AD structure 01 # Flags AD type 06 # Flags value 1A # Number of bytes that follow in second (and last) AD structure FF # Manufacturer specific data AD type 4C 00 # Company identifier code (0x004C == Apple) 02 # Byte 0 of iBeacon advertisement indicator 15 # Byte 1 of iBeacon advertisement indicator

Distance Estimation Estimation based on RSSI TxPower field is used to judge distance Very unreliable Distance estimates change when conditions change (ambient temperature, number of people etc.) Beacon calibration on location is imperative

Слайд 4

Additional Requirements 100ms advertisement rate Calibration must be performed on installation Devices should not be connectable iBeacon is an Apple trademark - self certification available through the MFi programme

Слайд 5

iOS Support iBeacon is supported natively in iOS 7+ as part of CoreLocation iOS devices can both detect iBeacons and act as iBeacons Apps can subscribe to receive background notifications Apps receive notifications even if they are closed and completely shut down iBeacon notifications persist even after device restart

Слайд 6

Android Support No official Android support Very few BLE enabled devices out there No peripheral profile in Android - device can’t act as iBeacon Problems with BLE stack implementation - very unstable, sometimes WiFi and BLE are in conflict 3rd party libraries used to get similar functionality as in iOS - Radius Networks’ open source library available on GitHub

Windows Support
