A Bluetooth beacon is a tiny wireless device based on Bluetooth technology. While installed inside buildings, it transmits a permanent radio signal that can be received by smartphones, points of access, or gateways. Bluetooth beacons are installed in stores, museums, industrial enterprises, and other rooms for collecting data on movement, delivering information, and relevant advertisements to users. They differ in low energy consumption and can transmit data to a distance of 40-60 m.

For the first time, radio beacons were presented by Apple at the Worldwide Developers Conference (WWDC) in 2013. One year later about 50 out of a hundred biggest retail chains in the USA started using them in their stores and in the following years, Bluetooth beacons became popular in other countries of the world. At present they are considered a communicative bridge connecting the physical and digital world.

Constructive peculiarities of the BLE beacon

The autonomous Bluetooth beacon consists of a plastic case with the following components inside:

  • Tiny ARM computer.
  • Bluetooth Smart communication module.
  • Power battery.

The ARM central processor is equipped with a small antenna that ensures the transmission of electromagnetic waves of a certain frequency and length.

Working principles of beacons

The working principles of beacons are based on transmitting radio signals that can be received by a special BLE gateway. After installing, the Bluetooth beacon starts sending signals with the specified interval. When the mobile device with the pre-installed application or turned-on Bluetooth/Wi-Fi gets into the range of the beacon, it recognizes these signals and starts performing certain tasks (sending push notifications or contextual advertisements to users).


Indoor navigation

Using beacons navigation helps companies to improve the quality of the services rendered to clients. Visitors are provided with indoor navigation with the possibility of building interactive maps in real-time. Using the mobile application, the person can create routes to the points of interest and quickly find the necessary places inside the building with high Bluetooth beacon location accuracy. Thus, Bluetooth Low Energy beacons in stores can make it possible to search for the required goods and, while visiting exhibitions and museums, quickly get to the exhibits of interest. Such an approach significantly improves the user experience of clients and provides companies with direct channels of communication with visitors.

Location tracking

Exact positioning is an actual solution for a large enterprise. Bluetooth location beacons perform tracking function successfully and help to define quickly the location of a person or an asset. The technology can help to:

  • Track the movement of people, equipment, transport.
  • Detect the misuse of working time.
  • Timely react to emergencies.
  • Control and redirect the flows of people.

Tracking assets and employees

Bluetooth beacons play an important role in ensuring safety in the enterprise. They can be installed on the equipment or built in the employees’ wearable devices, which allows tracking their movement. Thanks to the implementation of Bluetooth proximity beacons, the usage of the positioning system becomes an effective solution in preventing emergencies and avoiding the embezzlement of company property. Moreover, the devices help to control the staff performance. They can fix the time of attending the place, lateness, the absence at working places. The technology makes it possible to build interactive maps with access zones and perform tracking unauthorized access to such places.

Attendance analytics

The Bluetooth low energy beacon technology offers infinite opportunities for analyzing the attendance of stores, hospitals, administrative buildings, and other institutions. They help to build heat maps, develop visitor flow maps, and define the fact and frequency of the enterprise attendance. Thanks to the obtained information, marketers can better understand visitors’ behavior and personalize the offers for specific clients.

Social and marketing interaction

While using the beacons location technology, users can be provided with attractive and relevant content. Devices can easily define the location of users, allow evaluating their behavior, and further deliver the information, according to the conducted analysis, to the users’ smartphones. Clients will get targeted push-notifications that can contain the following:

  • Greetings.
  • Notifications on current sales and special offers.
  • Useful information on goods or services.
  • Advertising proposals.

The given approach increases user loyalty makes the company more attractive for clients and encourages them to come back.

Tracking flows of people for ensuring safety at the time of Covid-19

In the face of the pandemic, BLE beacons help the company management to undertake effective measures on preventing the spread of Covid-19 among the staff and visitors. Some vital tasks can be solved using the Bluetooth beacon tracking technology, including:

  • Keeping social distancing – beacons send signals on the crowding of people in rooms or the necessity to increase the distance between users, which helps to react timely to the situation.
  • Tracking contacts – positioning makes it possible to detect the number of contacts of some definite person and also estimate the duration of interactions.
  • Tracking vital signs – after implementing into bracelets or individual tags on clothes, they can measure the body temperature, the pulse rate, and other parameters.

Advantages and disadvantages of BLE beacons

One of the main advantages of these devices is their affordable cost and simple mounting. The installation of the beacon doesn’t take much time. They can be mounted on stationary and moving objects. The beacon is a transmitter that is attached to the surface and can be easily adjusted for work. Due to its low cost and low energy consumption, the device can be used for solving complicated technical tasks. The Bluetooth beacon is compatible with most mobile devices, which allows users to select the most optimal gateway.

Moreover, beacons ensure many benefits for marketers. They provide specialists with a new channel of interaction with clients and guarantee the following things:

  • High level of clicks. As the statistics show, the CTR indicators of the marketing campaigns with beacons are much higher than in other advertising types. Thus, while using beacons, the click-through rate is 80% more than the similar rate in media ads.
  • Possibilities for Internet retargeting. Thanks to beacon navigation systems, it is possible to communicate with clients even when they have left stores. If buyers were looking through the advertisements inside the store, marketers can later retarget them via Google Ads or Facebook.
  • Returns on investment. Beacons are considered an economical way of interacting with customers, which allows reducing the costs of implementing the marketing strategy. According to the research, while using beacons, retailers can increase their profit on average by 9%, having the return on investment at about 175%. For small businesses, the ROI can reach 365%.
  • Detailed analytics. The beacon-based positioning systems can monitor the behavior of visitors and get a detailed analysis of their actions for further optimization of the company’s operations. The technology allows understanding customers’ preferences, evaluating their buying habits, and creating personalized advertising campaigns for increasing profits.

Alongside the advantages, Bluetooth beacons have some minuses. For example, they can’t work independently. The device is a part of the general system and its functioning depends on the compatible equipment. Its performance can be restricted by the quality of the Internet connection. If it’s unstable or poor, the smartphone can’t effectively receive radio signals from the beacons and execute the set actions.
