A beacon is a small device that uses Bluetooth Low Energy (BLE) to send signals to nearby devices. These signals can trigger actions like sending notifications or providing location-based information. In this article, we will explore what a beacon is, how beacons work, and their many uses.
What are BLE Beacons?
Bluetooth beacons are small, battery-powered devices that transmit signals via Bluetooth Low Energy (BLE). At regular intervals, these beacons emit data packets, triggering specific actions on nearby Bluetooth-enabled devices. By bridging the physical and digital worlds, they enable devices to recognize and interact with their surroundings using Bluetooth low-energy beacons.
The primary function of a Bluetooth beacon is to transmit a unique identifier that provides contextual information to nearby devices. This identifier can be used to deliver personalized experiences, such as sending promotions to a shopper’s smartphone when they enter a store or guiding a visitor through a museum exhibit.
Bluetooth beacons enable user experiences by facilitating seamless interactions between mobile devices and the physical world. As technology evolves, these applications are expanding, offering fresh opportunities for businesses and consumers.
Evolution of Bluetooth Beacon Technology
The journey of Bluetooth beacon technology began with the development of Bluetooth itself in 1989 by Dr. Nils Rydebeck and Dr. Johan Ullman. However, the real turning point came in 2010 with the release of Bluetooth Low Energy (BLE). BLE provided a power-efficient communication method, laying the foundation for modern beacon technology.
Apple’s introduction of the iBeacon protocol in 2013 marked a significant milestone, spurring widespread adoption of Bluetooth beacons. Google followed with the Eddystone protocol in 2015, expanding options for developers. By 2014, over half of the top 100 US retailers experimented with beacon technology, highlighting its rapid growth and potential.
The development of standards like iBeacon and Eddystone ensured interoperability and broadened the scope of beacon applications. These advancements, along with the creation of the Physical Web, have significantly bridged the gap between physical and digital interactions. The introduction of the Eddystone-EID standard in 2016 further enhanced beacon capabilities with features like encrypted identifiers.
How Bluetooth Beacons Work
Bluetooth beacons continuously emit Bluetooth signals containing a unique identifier, which can trigger predefined actions on nearby devices. These signals are broadcasted using radio waves, typically at regular intervals, and consist of short packets of data that nearby devices can pick up. Operating in the 2.400–2.4835 GHz ISM band, these beacons ensure low power consumption while maintaining effective communication.
When a Bluetooth beacon transmits a signal, it sends out a radio signal composed of letters and numbers. This signal can be received by any compatible device within range, allowing it to perform specific actions based on the data received to transmit data. The beacons function as one-way transmitters, broadcasting their identifier to any listening device.
To understand how Bluetooth beacons function, one must consider their signal transmission, components, and battery life. Each aspect significantly influences the beacons’ overall effectiveness.
Signal Transmission and Range
Bluetooth beacons operate within a radio frequency range of 2.400 to 2.4835 GHz, part of the ISM band. The transmission of signals relies on minimal obstructions, as physical objects can significantly impact signal strength and reliability. The typical operating range of Bluetooth beacons varies from 2 to 80 meters, although most beacons have a reliable transmission distance of up to 30 meters.
Beacons can be configured for beacon signal strength and transmission intervals to achieve desired coverage. Although the theoretical maximum range is under 100 meters, practical limitations like obstacles and interference typically reduce this distance. Proper placement and configuration are crucial for effective communication and coverage.
Components of a Bluetooth Beacon
The internal components of a Bluetooth beacon typically include a microprocessor, a radio, and a battery. These elements work together to transmit signals efficiently and cost-effectively. Additionally, many beacons come equipped with sensors such as accelerometers to enhance their functionality.
The simplicity of these components makes Bluetooth beacons easy to maintain and deploy in various settings.
Battery Life and Maintenance
A major advantage of Bluetooth Low Energy technology is its long battery life. Due to their energy-efficient design, BLE beacons can operate for years on a single battery. They usually use small lithium chip batteries or connect to power sources like USB plugs. BLE technology’s low power consumption, using only 1-20% of the power required by full Bluetooth, further extends battery life.
However, the range and frequency of signal transmissions affect battery consumption. Higher signal strength and more frequent transmissions can deplete the battery faster. Regular maintenance, including battery replacement, ensures continuous operation.
Despite these challenges, the long operational duration and low maintenance requirements make BLE beacons a practical choice for many applications.
Key Features of Bluetooth Beacons
Bluetooth beacons are characterized by their low power consumption, compact size, and ease of deployment. These features enable beacons to operate for extended periods, with some models lasting several years on a single battery. These devices’ compact and lightweight design makes them easy to install in diverse environments, from retail stores to industrial sites.
Another significant feature is their ability to transmit signals over a typical 2 to 30-meter range without requiring an internet connection. This makes them ideal for applications where continuous connectivity might not be feasible. As standalone broadcasters, Bluetooth beacons can effectively bridge the gap between physical locations and digital interactions.
Benefits of Using BLE Beacons
BLE beacons offer numerous benefits, making them a cost-effective solution for businesses. These low-cost devices enable companies to deliver personalized experiences without substantial investments.

They also outperform RFID beacons in terms of operational range.
While Wi-Fi beacons offer high location accuracy and extended range, they consume significantly more power and are more costly to deploy. LoRa beacons, capable of long-range communication up to 15 km, operate at a lower data rate, making them less suitable for high-speed data transmission.
BLE beacons strike a balance by offering a decent range, low power consumption, and cost-effective deployment.
Challenges and Limitations of BLE Beacons
Despite their benefits, BLE beacons face certain challenges and limitations. Signal interference from other devices operating on the same frequency can affect detection accuracy. Environmental factors such as thick walls or severe weather can also compromise the reliability of beacon signals.
Battery life is another consideration, as higher signal strength and frequent transmissions can lead to quicker battery depletion. Additionally, BLE beacons cannot determine the direction of users and may struggle to track moving devices accurately. Addressing these limitations requires careful planning and deployment to ensure optimal performance.
