What is Beacon?

Similar to Near Field Communication (NFC), Beacons interact with smartphones when positioned within a certain radius of distance using Bluetooth . It's basically a friendly name for technology " indoor proximity system or "proximity system indoors".

In practice, it allows you to locate objects (or people that carry these objects) much more accurately indoors. Beacons are indoors as the GPS is outdoors.

For deployment on Android, you need to give Bluetooh access to your Android Manifest:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

See here in this article on Building an Android Beacon (Android iBeacon Tutorial Overview) a complete implementation idea.

Google provides a library for deployment using .NET . See more details on Google Proximity Beacon API Client Library for .NET .
