Beacons : What They Are ? How
They work ? Why They are
Important ?

What are Beacons ?
• Beacons are small piece of hardware devices
that can emit and receive BLE signals.

Bluetooth Technology ?
• Radio
• Software Stack

Bluetooth LE : What is it ?
A Specification With
A New Radio, New Software stack & New Profile
Architecture
• Used to create Bluetooth LE chipsets - e.g.
contact chipsets
• Chipsets are embedded in the devices

Bluetooth Classic Vs Bluetooth LE

Bluetooth X Y Y X X
BLE X X X X Y

Bluetooth Classic Vs Bluetooth LE

Currently Supported by devices :
GOOGLE Nexus 4,5,7,10
GPS Cameras
Security Equipments Laptops

90% of devices will be BLE enabled
by 2018

Beacons/BLE : How They Work ?
• BLE enabled devices or Beacons can transmits
small packets of data.
• This wakes up a “listener/receiver” to let it
know that it’s there.
• Which then lets you calculate the proximity to
the Beacon and show relevant information to
visitors.

Why are Beacons important ?
Advantage to Developers
Before BLE After BLE
An app would need to be running
in the foreground or background
to communicate with a BLE
device.
An app can be launched into
background if a specific BLE
device is recognized.

Beacons & GPS
• Beacons can be thought as an extension of
location technology.
• It’s lot like GPS but uses a lot less battery.
• GPS does not work well once you go inside
but Bluetooth LE works.

Beacons & GPS
GPS is a Location Technology
Bluetooth LE is a Proximity Technology.

Why Proximity Matters ?
We can now deliver the content and
experiences to users based on precise
proximity to things in physical world

Customer Passes By a Retail
Store

Customer Receives Notifications and
Offers

Indoor Navigation : Showing the
Route

Presence Detection via Proximity

Case Study : Retail Business
• Greet Customers when they arrive.
• Send special offers and coupons at specific
locations on store.
• Offer personal pricing.
• Implementing proximity driven ad-screen.

Real-Time
Analytics & Statistics

Statistics & Analytics : Retail Business
• Aggregate and analyze behavior and traces of
the customers.
• Analyze interests and shopping decisions of
your customers -‐ in your shop but even off
location.
• Be able to take action on customers behavior
and feedbacks.

Statistics & Analytics : Retail Business
• Increase in-store visitor experience.
• Optimize Target Online Marketing.
• Have meaningful dashboards at your
fingertips
• Run cross-dataset analysis, do peer
comparisons, and generate actionable report

Android Beacons
Supported on Android API >= 4.2
• All android devices above 4.2 have BLE enabled in
itselves.
• They can act as a Receiver/Listener and can wake up
once supported application receives a signal
• Android Devices having version > 4.4 i.e. Android-L
devices can also act as a BLE Transmitter

Practical Use Case
Luggage Tracker

Use Case : Luggage Tracker
1. Implement a broadcast receiver to catch
broadcasts for turning bluetooth on and off.
2. Start a service when bluetooth turns on.
3. Stop service when bluetooth turns off
4. Register a listener to listen for nearby beacon
devices

Implementing Broadcast Receiver
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if
(BluetoothAdapter.ACTION_STATE_CHANGED.equals(intent.getAction())) {
int state =
intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, -1);
Intent i;
switch (state) {
case BluetoothAdapter.STATE_OFF:
if (MyBeaconService.isStarted) {
i = new Intent(context,
MyBeaconIntentService.class);
i.putExtra("StartBeaconService",
false);
context.stopService(i);
}
Log.i(TAG, "Bluetooth State : OFF");
break;
case BluetoothAdapter.STATE_ON:
Log.i(TAG, "Bluetooth State : ON");
if (!MyBeaconService.isStarted) {
i = new Intent(context,
MyBeaconIntentService.class);
i.putExtra("StartBeaconService",
true);
context.startService(i);
}

Registering Ranging Listener in
Service’s onCreate() method
@Override
public void onCreate() {
super.onCreate();
beaconManager.setMonitoringListener(new
BeaconManager.MonitoringListener() {
@Override
public void onExitedRegion(Region arg0) {
Util.postNotification(getBaseContext(),
"Alert Luggage Tracker",
notificationManager, 1,
AllDemosActivity.class);
}
@Override
public void onEnteredRegion(Region arg0, List<Beacon>
arg1) {
}});
}

Connecting to BeaconManager’s Service
in Service’s onStartCommand()
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
beaconManager.connect(new
BeaconManager.ServiceReadyCallback() {
@Override
public void onServiceReady() {
try {
beaconManager.startMonitoring(BEACONS);
} catch (RemoteException e) {
Log.e(TAG, "Cannot start
ranging", e);
} catch (Exception e) {
e.printStackTrace();
}
}
});
return START_NOT_STICKY;
}

Technical pitfalls of Beacons ?
• Bluetooth must be turned on.
• Your app must be installed on users devices.
• You can't trigger mobile beacon or iBeacon to trigger
installation of an app.
• Location services must be enabled for the specific
application.
• To download real data we must have an app connected
via internet connection.
