Beacon technology has evolved dramatically since its inception in 2013, growing into a multi-billion-dollar industry that extends far beyond the first retail proximity marketing use cases that drove them.

This article examines the introduction of classic Beacon technology like iBeacon and Eddystone and the evolution to modern Smart Beacon solutions like Blecon, tackling requirements for security, two-way communication, security, time synchronisation and deployment options that address the more complex demands of enterprise IoT applications.

A Brief History of Classic Beacons

The Beacon journey began in 2013 with Apple's introduction of iBeacon, leveraging the advertising features of Bluetooth Low Energy. This protocol brought a new form of physical location awareness to mobile apps through a simple but powerful mechanism: a device broadcasting a Universally Unique Identifier (UUID) that nearby phones could spot and react to.

The early adoption was driven by some initial marketing use cases aimed at enabling new customer experiences:

• Retail stores using beacons to trigger proximity-based marketing
• Shopping malls using beacons to enable indoor location apps
• Museums using beacons to identify exhibits and trigger experiences

Beyond the UUID identifying the application they were associated with, Major and Minor identifiers could be used to represent location, exhibit or other aspects within those custom applications.

In 2015, Google responded with Eddystone, a competing protocol that expanded beacon capabilities beyond Apple's ecosystem. Whilst again the initial focus was on similar marketing applications, Eddystone did introduce multiple data frame types to expand possibilities:

• UID (Unique Identifier): Enabled basic proximity detection
• URL: Broadcast web links accessible without dedicated apps
• TLM (Telemetry): Provided beacon health monitoring
• EID (Ephemeral Identifier): An alternative identifier with security properties

Both iBeacon and Eddystone are still widely used in these application areas, despite them not getting as much visibility since their initial launch years.

Market Evolution and Asset Tracking

Whilst marketing applications may have been the driver to integrate Beacon technology into mobile OS platforms, a killer app for Beacons quickly emerged; asset tracking. 

Rather than Beacons being attached in fixed locations to trigger apps, they were quickly attached to moving assets; with mobile devices and dedicated hardware gateways used to spot and track their location. 

In the consumer space, this would be readily recognised in solutions like Tile and more recently AirTags and the Apple Find My network, helping consumers locate objects like keys or suitcases. 

However, in industry, asset tracking using Beacons has exploded. The Beacon market has grown significantly, reaching an estimated valuation of $3 billion in 2023 and is now projected to expand to $3.82 billion in 2024, with long-term forecasts predicting $16.05 billion by 2030 (). 

While these Classic Beacon technologies have triggered the development of a range of applications, they all share a significant limitation: they are broadcast-only devices. These beacons "shout" their location into the void, relying on nearby devices to listen and hear them; they cannot confirm if messages are received or facilitate any form of two-way interaction or security.

So whilst early beacon technologies laid the groundwork, limitations from their heritage as a marketing tool have meant enterprise use cases have rapidly pushed beyond their capabilities.

Why Industry Demands More

The demands of commercial and industrial applications have evolved far beyond what Classic Beacons can offer. Modern enterprises require security and reliability in beacon deployments, and devices must ensure messages are not just broadcast but also received and acknowledged by cloud servers.

This confirmation mechanism serves to maintain data integrity across the system and can help ensure no gaps or errors in data. Furthermore, the reliability requirement extends beyond simple message delivery to encompass the entire 2-way data flow from beacon to backend systems.

Flexibility is another essential requirement. Modern IoT systems need the capability to push updates or configure devices remotely. Over-the-air firmware updates, for example, eliminate the need for physical intervention, saving both time and resources. This kind of adaptability is crucial for managing large-scale deployments or responding quickly to changing operational needs.

Finally, security has become a non-negotiable priority. Robust encryption and secure communication channels are vital to prevent unauthorised access or tampering, especially in industries handling sensitive data or critical operations. Without these safeguards, the risk of data breaches or operational disruptions becomes significantly higher.

This market maturation of requirements mirrors the technological progression from Classic Beacons to Smart Beacons; devices with the capabilities for secure 2-way communication and flexible deployment. As industries have discovered new applications and use cases, they've demanded more sophisticated capabilities beyond simple proximity detection. 

The market valuation demonstrates not just the technology's widespread adoption, but also its crucial role in modern business operations. This shift from marketing technology to mission-critical infrastructure has driven the development of more advanced beacon solutions capable of meeting enterprise-grade requirements.

As these enterprise requirements have become clear, a new generation of beacon technology has emerged to address them.

Enter Blecon

Blecon represents the next generation of Smart Beacon technology, addressing the limitations of iBeacon and Eddystone for modern use cases and requirements. Here’s how Blecon transforms Beacon capabilities:

Two-Way Communication

Unlike classic Beacons, which only broadcast, Blecon enables bidirectional communication. For example:

• A Blecon-enabled smart beacon can confirm that its message was received by the cloud server, ensuring reliable data transmission.
• Businesses can push firmware updates or reconfigure devices remotely, eliminating the need for costly on-site interventions.

Enhanced Security

Like classic beacons, Blecon requires no pairing. However, it incorporates robust encryption and authentication protocols to secure data transmissions. This makes Blecon ideal for industries where data integrity and privacy are paramount.

Time-Based Insights

Unlike iBeacon and Eddystone, Blecon supports timestamping and synchronisation, enabling more advanced use cases. For instance:

• Supply Chain Monitoring: Knowing when a temperature-sensitive product, such as food or vaccines, deviates from the correct range allows businesses to determine precisely where and when spoilage occurred, or if the product is still safe to use.
• Operational Efficiency: Time data can be used to measure equipment uptime and downtime, enabling predictive maintenance.

Scalability

Blecon’s cloud-enabled architecture allows seamless deployment and management of devices, ensuring that applications can grow without sacrificing reliability or performance.

iBeacon Vs Eddystone Vs Blecon

When comparing beacon technologies, several key features stand out that highlight the evolution from classic to smart beacons:

Identity & Location

All three technologies excel at core beacon functionality - providing identity and location services. However, their approaches differ:

• iBeacon uses a proprietary UUID system with Major/Minor values for precise location hierarchies, ideal for large-scale retail deployments
• Eddystone offers flexible UID frames and URL broadcasting for cross-platform compatibility
• Blecon devices all automatically create a globally unique ID and associated security materials, enabling attestation of devices and encryption of communication, and full global location and identification

Time Synchronisation

Time awareness marks a significant advancement in beacon technology:

• Traditional beacons (iBeacon and Eddystone) lack time synchronisation, limiting their ability to provide temporal context
• Blecon's time-aware architecture enables precise event logging, tracking and temporal analytics, crucial for supply chain monitoring and operational efficiency

Communication Capabilities

The evolution of communication protocols shows the technological leap:

• iBeacon offers basic one-way broadcasting
• Eddystone introduced multiple frame types (UID, URL, TLM, EID) for enhanced broadcast options.
• Blecon changes the equation with true two-way communication, enabling confirmed message delivery, remote configuration and OTA updates.

Security Framework

Security features highlight the generational gap:

• iBeacon's basic broadcasting lacks built-in security measures
• Eddystone introduced the EID frame, a rarely implemented privacy feature
• Blecon implements end-to-end encryption and secure authentication protocols - even the mobile handsets and hotspots need not be trusted

This comprehensive comparison reveals how Blecon addresses the limitations of classic beacons while maintaining their ease of use - all without pairing.

Conclusion 

The beacon technology landscape has transformed from simple proximity-based devices into sophisticated IoT infrastructure. With market valuations expected to grow to $16.05 billion by 2030, the demand for advanced solutions like Blecon highlights the increasing importance of scalability, security, and reliability.
