Navigine - Using BLE for Indoor Navigation and Positioning

For many years the GPS has been considered the best solution for object location. However, it has limited possibilities especially while moving inside premises, so in the modern world, it is being substituted by Bluetooth. At present Bluetooth Low Energy (BLE) is probably one of the most convenient technological solutions for indoor positioning which allows developing effective navigation systems.

 

How the system works

Indoor positioning Bluetooth is carried out using special beacons that are installed on objects and send signals at regular intervals. Due to their tiny size, they are widely used in a wide variety of geolocation solutions.

Navigation with iBeacon is carried out through a mobile application. The smartphone receives Bluetooth signals from beacons inside the location and sends certain information to users, such as location data, directions to desired places, advertisements, push notifications.

For project realization, two technologies can be applied:

  • iBeacon – an in-building positioning system that allows exchanging data between BLE devices and beacons. The technology was developed in 2013 and since then it has been actively used.
  • Eddystone – a new standard of beacon work from Google. It is an extended version of BLE and makes use of the key ability of beacons to transmit a unique identification code at short distances using Bluetooth signals.

 

Pros and cons

The indoor positioning system using Bluetooth has a wide range of benefits for developing projects. With its help, it’s quite easy to orient in big buildings, quickly find the needed objects, perform analytics of visits and movements inside the premises.

The main advantages of the technology are the following:

  • Possibility to build the infrastructure based on available and inexpensive equipment.
  • Simple system management without any specific expertise and skills.
  • Energy efficiency.
  • Optimization of interaction between system users and clients.
  • Locating objects with an accuracy of several meters.
  • Easy-to-install beacons.

Alongside with advantages, Bluetooth indoor positioning system has some disadvantages, such as its relatively small working distance (on average, up to 30 m), the necessity to use applications for clients’ solutions, employment of additional equipment.

 

Spheres of application

The Bluetooth navigation system has found successful application in many spheres. The most common ones are:

  • Healthcare. Thanks to this system, patients can easily orient in big medical institutions, find the necessary rooms, get information on doctor’s appointments.
  • Industry. The system allows optimizing production processes and monitoring the company’s assets. Any object that has to be followed is equipped with a small label with a beacon. The object's location and its performance can be displayed in the web interface at any time.
  • Warehouses. BLE beacons can be placed on important and expensive things. When the beacon leaves the defined zone, the alarm signal is activated or the system gets a security notification.
  • Transport. Beacons ensure convenient navigation for airline or railway passengers inside transport hubs. Using the Android and iOS applications, passengers can find the necessary routes or important objects, such as ATMs, recreation rooms, and ticket offices.
