Introduction
Beacons are small wireless devices that broadcast signals using Bluetooth Low Energy (BLE), or Bluetooth SMART technology. Mobile apps on compatible devices are able to listen for signals from beacons placed in the physical world and then trigger an experience via the app.
Beacon enabled apps are notified when the device enters or exits the range of a beacon, and are also able to monitor the distance from the beacon as it changes, often referred to as 'ranging'.

Bluetooth Low Energy
BLE or Bluetooth Smart is an intelligent and power friendly version of Bluetooth wireless technology and exchanges data over short distances using radio transmissions. The power of BLE is in its ability to work with an app on a smartphone, tablet or any other compatible mobile device.

The Beacon System

The Beacon system from Apple can be broken down into two parts:
• A piece of hardware – the “Beacon”, which constantly broadcasts a Bluetooth Low Energy signal. This transmits a unique identifier (UUID) and two further identifiers; major and minor (unsigned 16 bit integer values), which can be used to identify the beacon.
• Application Programmable Interface (API) - An API to search for beacons with a certain UUID and optionally a specific major and minor value. iBeacon adds the possibility for the developer to subscribe to beacons like you would subscribe to geolocations. This enables the app to get notifications (whether the app is currently running or not) when the user gets within range of a specific beacon.

Importance
• High degree of accuracy
• Low impact on battery life
• Low cost of entry
• No Internet connection required


Security

Some of the most common beacon security myths:
• Beacons are transmitting personal data:
Beacons don’t transmit any personal data. In fact, beacons don’t receive any data at all.
• Beacons are tracking my location:
Beacons can’t track your location. The only thing they can do is let your mobile device know that you’re nearby.

Compatibility
Beacons work with both Android and iOS. They were initially introduced in iOS7 and are compatible with every Android version > 4.3
This puts beacon functionality in 300 million + devices.

Conclusion

Beacons transmit a low energy signal from a device with a radius of 0-50 meters to broadcast static pieces of data within short distances.
In a nutshell, our basic requirements for an operational beacon are:
1. Beacon enabled mobile app
2. Network of deployed beacons
3. Bluetooth switched on and relevant permissions

Without a doubt, the Beacon is a useful convergence device that can be given a shot at, which is for sure a revolution in technology

  3. 3. INTRODUCTION 3 Beacons are small devices that broadcast a Bluetooth Smart radio signal to trigger alerts or messages on consumers phones. Instead of using satellites to triangulate your position in the world as GPS does, beacons transmit a low energy signal from a device with a radius of 0-30 meters to provide unprecedented location services that can accurately measure positioning down to inches.

INTRODUCTION(cont.) 4 Mobile apps on compatible devices are able to listen for signals from beacons placed in the physical world and then trigger an experience via the app. Beacon enabled apps are notified when the device enters or exits the range of a beacon, and are also able to monitor the distance from the beacon as it changes, often referred to as 'ranging'.This is in contrast to GPS, which uses latitude and longitude to define a devices location.

The only role of the beacon is to notify the smartphone of its existence at the physical location. Source: beaconateddystone.org
  9. 9. Bluetooth Low Energy 9 BLE or Bluetooth Smart is an intelligent and power friendly version of Bluetooth wireless technology and exchanges data over short distances using radio transmissions.The power of BLE is in its ability to work with an app on a smartphone, tablet or any other compatible mobile device.The technology itself is simple, secure and featured in billions of devices ranging from mobile phones and computers to medical devices and home entertainment products. It is intended to replace the cables that connect devices, while maintaining high levels of security. It is highly likely that BLE will be one of the key technologies behind the growth of the network of physical objects that can exchange data via the existing Internet infrastructure.
  10. 10. Beacons are small wireless devices that broadcast signals using Bluetooth Low Energy (BLE), or Bluetooth SMART technology. Mobile apps on compatible devices are able to listen for signals from beacons placed in the physical world and then trigger an experience via the app. By experiences we mean things like sending a notification, coupon, video, form, URL or other forms of media that are relevant to a person's exact location. Beacon enabled apps are notified when the device enters or exits the range of a beacon, and are also able to monitor the distance from the beacon as it changes, often referred to as 'ranging'. The range of a beacon varies depending on the manufacturer, hardware settings and physical surroundings, but can typically be configured anywhere from 0 to 30 meters, creating a wide range of use cases.

  14. 14. IMPORTANCE 14  High degree of accuracy: Beacon technology allows a mobile device to understand it's exact position  Low impact on battery life: Bluetooth technology is designed to have very low power consumption, which means that beacon powered apps have minimal impact on the devices battery life.  Low cost of entry: Setting up and taking advantage of a beacon network is relatively low cost when compared to other technologies such as Wi-Fi.  No Internet connection required: Mobile apps can pick up beacon signals without an Internet connection and store data locally on the device.

  16. 16. SECURITY 16 Signals that are broadcast using BLE are considered public, meaning another mobile app can potentially use the signal for their own purposes. But its not true.

In fact, beacons don’t receive any data at all.  Beacons are tracking my location: Beacons can’t track your location.The only thing they can do is let your mobile device know that you’re nearby.
