Extensive Guide to Bluetooth Low Energy (BLE) Beacons

Contents

What are beacons and why should I care?

Beacons are devices that broadcast signals at a certain interval. In other words, Beacons allow applications to understand their location on a hyper-local scale and sends signals to users based on their specific geographic location. It’s kind of like GPS for indoors that powers all kinds of possible uses. These uses of beacons in the real world are extremely diverse and endless. They essentially bridge the online and offline world while gathering invaluable data. That’s why they’ve found applications in industries ranging from retail and logistics to airports and museums.

While every industry can benefit from proximity and location technologies, beacons play especially essential role in healthcare. Hospitals and clinics are high-stakes environments where staff, patients, and equipment are in constant motion, and where delays, inefficiencies, or lack of visibility can directly impact patient outcomes and operational costs.

Beacons address these challenges by:

  • Providing real-time visibility into the location and status of critical medical assets.
  • Improving patient safety and flow through monitoring and navigation support.
  • Enhancing staff efficiency by reducing wasted time searching for equipment or colleagues.
  • Supporting regulatory compliance around hygiene, medication storage, and reporting.

What are Bluetooth Low Energy (Bluetooth LE) Beacons and why are they special?

Bluetooth LE beacons are, as the name suggests, beacons that use Bluetooth Low Energy technology. Just how much of an impact does this have?

  • Cost: the technology enables 60-80% cheaper cost of operation than competing standards

  • Power Consumption: 50-99% less power used means the average beacon can last up to 2 years (or even 5 years with our beacons)

  • Application: Bluetooth LE technology is perfect for beacons since applications only require minimal periodic transfers of data. As Bluetooth LE can be found almost everywhere, beacons, too, can function…well, almost everywhere!

How do Bluetooth Beacons Work?

At their core, Bluetooth beacons are simple transmitters. They do not collect or store data on their own—they only broadcast a small radio signal at set intervals using Bluetooth Low Energy (BLE).
Here’s how the process works at the healthcare example:

1. Beacon Transmission

  • A beacon constantly sends out a small packet of information.
  • This packet can contain an ID number, a URL, or sensor data (like temperature).

2. Signal Detection

  • A smartphone, wearable, gateway, or IoT hub within range “hears” the signal.
  • The receiving device does not just know that a beacon is nearby, but also how near it is, based on signal strength

3. Data Interpretation

The receiving system (hospital app, RTLS platform, or cloud service) interprets the signal.
For example:

  • A staff badge beacon tells the system which nurse is in which room.
  • An asset tracking beacon shows where an infusion pump is located.
  • A sensor-enabled beacon confirms that a medication fridge is within the required temperature range.

4. Action & Analytics

  • Once detected, the signal triggers workflows or is logged for analytics.

Examples in healthcare:

  • Instant location updates when equipment moves.
  • Alerts if a patient wanders outside a safe zone.
  • Compliance reports showing hand hygiene or storage temperature history.

Bluetooth Beacon Technology – Eddystone and iBeacon, Which One To Choose?

Beacons all use Bluetooth Low Energy (BLE) to transmit signals, but the format of those signals depends on the protocol. The two most widely used protocols are iBeacon (Apple) and Eddystone (Google). Both can be implemented in hospitals, and both can support healthcare use cases like asset tracking beacons and patient safety solutions. The key difference lies in features, complexity, and regulatory alignment.

iBeacon

iBeacon transmits a UUID, a Major, and a Minor value (16, 4 and 4 digits respectively). One quick reminder: beacons do not do the tracking. iBeacon requires an app to receive, process and/or track the beacon. Works with iOS and Android, but native to iOS (works better with iOS). This makes it easy to align with HIPAA/GDPR, as long as hospital IT systems handle data securely on the backend. In healthcare it works best for straightforward use cases such as staff badges, patient check-ins, or simple location-based triggers.

Eddystone

Eddystone can send 3 different frame-types: Eddystone-UID, Eddystone-URL, or Eddystone-TLM.

  • Eddystone-UID is essentially identical to that of the iBeacon.
  • Eddystone-URL tells a smartphone or device to open an URL. Does not require developers app to be installed, only the latest Chrome application.
  • Eddystone-TLM sends data from sensors, for example, tracking temperature so you can control the temperature in a warehouse.

Cross-platform, meaning it works well with not only iOS and Android, but any processor that supports Bluetooth beacons. Like iBeacon, Eddystone broadcasts non-sensitive signals. The regulatory focus is on how hospitals store and use the data collected, not on the beacon transmission itself. For hospitals it is particularly powerful for compliance-related use cases, such as monitoring medication fridges, blood banks, or lab environments where temperature control must be documented.

What does all that mean?

Too many technical terms? Don’t worry. If none of that makes sense or is of interest to you, I will simply sum it up:

iBeacon is simple to implement, has more documentation, but less features.

Eddystone has more features and sends more information than iBeacon, but it is more complicated to integrate.

Bluetooth LE Beacon Use Cases in Healthcare

Let’s face it, hearing about beacon specifications can be a bit dry sometimes; you want to see some real world examples and how you can benefit as well. 

In the early days, Bluetooth beacons were most visible in retail, events, and tourism, where they powered marketing campaigns, indoor navigation, and customer engagement. These “traditional” use cases focused on helping consumers interact with brands.

But the true potential of beacons lies far beyond marketing. Over the last few years, organizations have discovered that BLE beacon technology is far more powerful as a tool for data, visibility, and process optimization. Today, asset tracking and real-time location systems (RTLS) are leading the way, creating efficiency and safety in industries where every second counts especially in healthcare.

Hospitals are complex ecosystems with patients, staff, and equipment constantly on the move. Unlike retail or tourism, inefficiencies in healthcare don’t just cost money, they can affect patient outcomes, staff well-being, and regulatory compliance. That’s why BLE beacon asset tracking and workflow automation are now becoming essential infrastructure for modern hospitals, even if patients themselves never see or notice the technology.

1. Asset Tracking and Equipment Management

Every hospital leader knows the frustration: you invest heavily in medical equipment, yet staff still spend far too much time looking for it. A nurse on a busy shift might walk the entire floor searching for a wheelchair. A doctor preparing for a procedure may be delayed because a vital monitor can’t be located. The irony is that the equipment usually exists somewhere in the building – it’s just not where it’s needed. This wastes time, drives up costs, and puts patient care at risk.

This is exactly the problem that a Real-Time Location System (RTLS) powered by BLE beacon asset tracking solves. Here’s how it works in practice:

  • Each device—whether it’s an infusion pump, defibrillator, ventilator, or wheelchair—is tagged with a small asset tracking beacon.
  • These beacons send out a Bluetooth Low Energy (BLE) signal every few seconds.
  • Receivers placed throughout the hospital pick up those signals and send them to a central RTLS platform.
  • The system calculates the location of each beacon and displays it on a digital map of the facility, refreshing every few seconds.

For hospital staff, this means that equipment is no longer “lost.” A nurse can pull up the system on a workstation or mobile device and instantly see where the nearest available pump or wheelchair is. Biomedical teams can quickly find devices that are due for maintenance. Administrators can spot trends in under-utilization and redeploy resources where they’re needed most.

The value for hospitals is significant:

  • Time back to caregivers: Nurses and doctors spend less time hunting for equipment and more time with patients.
  • Better use of capital: When you know exactly what you own and how often it’s used, you buy fewer unnecessary backups and rentals.
  • Improved patient safety: Life-saving devices can be found immediately in emergencies.
  • Automated compliance: Maintenance records and equipment usage logs are generated automatically, supporting audits and inspections without extra administrative work.

2. Patient Safety and Flow Optimization

In hospitals, safeguarding patients and ensuring a seamless flow through their care journey are top priorities but they’re often challenged by patient wandering, room mix-ups, or delays between departments. Even simple inefficiencies can erode patient trust and raise safety risks.

Kontakt.io’s AI-powered RTLS BLE tags for healthcare transforms this dynamic by providing real-time visibility, seamless navigation, and operational intelligence – without disrupting the care environment.

3. Staff Efficiency and Safety

Healthcare professionals face escalating pressure. From overwhelming workloads, rising incidents of workplace aggression, and emotional strain that impacts morale and retention. For hospital leaders, ensuring caregiver safety is not just a regulatory obligation but a strategic imperative.

At Kontakt.io we created uniquely crafted BLE beacons that help to ensure staff safety and optimize their productivity. 

  • Peace of mind for caregivers: Nurses and staff wear lightweight smart badges with a discreet duress button. One tap calls for help and transmits their exact location, ensuring they’re never alone in a crisis.
  • Faster response to emergencies: Real-time location data guides responders directly to the staff member, indoors or outdoors. Security teams waste no time searching and can de-escalate situations quickly.
  • A safer, more supportive workplace: Visible protection builds trust and confidence, reducing stress and lowering burnout. Staff know their safety is a priority, which helps improve retention.
  • Smarter workforce management: Location insights show how staff move across departments, revealing inefficiencies and heavy workloads. Leaders can rebalance tasks and ensure better coverage where it’s needed.
  • Lower costs from avoided incidents:  Preventing injuries, claims, and lost workdays generates significant savings. Analytics highlight high-risk areas so issues can be fixed before they become costly problems.

4. Indoor Navigation and Wayfinding

Hospitals are often sprawling, complex environments that can overwhelm patients and visitors. Missed appointments and delays are more than just an inconvenience—they reduce operational efficiency, lower patient satisfaction, and cost hospitals revenue. Clear wayfinding is critical to ensuring people get where they need to be, on time, with less stress.

  • Fewer missed appointments: BLE-powered navigation apps guide patients and families from the entrance directly to the right floor, wing, or room—keeping schedules on track.
  • Less stress, better experience: Turn-by-turn wayfinding removes the frustration of getting lost in large hospitals, making patients feel more confident and comfortable during their visit.
  • Staff time saved: By helping visitors navigate independently, staff spend less time giving directions and more time focusing on patient care.

5. Hygiene and Compliance Monitoring

Preventing infections is one of the most pressing challenges for hospitals. Manual observation and reporting are unreliable, resource-intensive, and often fail to capture the full picture. A single missed step in hand hygiene can have serious consequences impacting patient safety, regulatory compliance, and even the hospital’s reputation.

Kontakt.io’s Hospital Hand Hygiene solution empowers caregivers to actively engage in infection prevention while giving leadership the tools to track, manage, and improve compliance.

  • Safer patients, fewer infections: Smart Badges automatically trigger hand hygiene reminders when staff enter or leave patient rooms, ensuring protocols are followed. By reinforcing good habits in real time, hospitals reduce hospital-acquired infections and protect patient safety.
  • Stronger compliance with less effort: Every hygiene event is logged automatically. Compliance data can be viewed by hospital, department, or even individual staff members, and audit-ready reports for the Joint Commission are generated with a single click, removing manual work while lowering regulatory risks.
  • Faster response to outbreaks: Badge-level RTLS data enables contact tracing in seconds. If an infectious disease is detected, hospitals can identify exposure paths immediately, contain risks, and prevent costly escalation.
  • Engaged staff and reliable resources: Compliance rates can be gamified to encourage positive behavior and foster accountability across teams. At the same time, the system monitors dispenser status and alerts staff when soap or gel dispensers are empty or malfunctioning—ensuring resources are always ready to use.

Main Considerations

If you’ve read/skimmed this far, you must be interested. So what else should you consider before going into the proof of concept stage?

Deployment

If you’re deploying a large amount of beacons, you must have the right set of tools and communication. There are things you absolutely must understand and some decisions you absolutely must make beforehand:

How are the beacons configured? How are they labeled for deployment? Are they continuously updated as the business purposes for the beacon changes? If you’re in need of some expert tips, feel free to check these out.

Fleet Management and Coverage

It seems a little unnecessary, but management will need to be considered during deployment. If you don’t understand how your fleet with function into the future, you’re probably going to get burned. One must routinely check on: missing/stolen beacons, the indicators regarding battery life, and categorization of the beacons.

The coverage or range of beacons vary largely depending on the environment. Fixtures, walls or even other signals may disrupt the coverage. It’s hard to estimate what the spread in beacons are, but we’d love to try.

Beacon Security

Beacons are now emerging as a gateway to complicated financial interactions, so now there are incentives for someone to gain access to your beacons. The Eddystone communication protocol is already secure, but iBeacon is vulnerable to piggybacking, cloning, hijacking and cracking.

Lucky for our users, all our beacons have Kontakt.io Secure, worlds only suite that protects you against all the security threats.

Of course, just because your beacons are secure doesn’t mean you shouldn’t worry about understanding how it works. I highly recommend reading up on how beacons work and why security matters. Beacon hardware is incredibly simple. That’s why security is of the utmost importance.

How to Choose Right BLE Beacon Solution Provider 

Not all beacon solutions are created equal. For hospitals, selecting the right partner goes far beyond hardware. It’s about finding a provider that delivers measurable outcomes, compliance, and long-term reliability. When evaluating options, consider these key factors:

  • Proven healthcare expertise: Hospitals operate under unique pressures from regulatory, clinical, and operational. Choose a provider with a clear track record in healthcare deployments, not just generic IoT projects. A healthcare-focused partner understands patient safety, staff workflows, and compliance requirements.
  • Scalability and ease of deployment: A solution should grow with your needs. Look for cloud-native platforms that can scale from a single ward to multi-site hospital networks, with rapid deployment that doesn’t disrupt daily operations.
  • Regulatory compliance and security: HIPAA and GDPR compliance are non-negotiable. Providers should offer secure data transmission, encryption, and audit-ready reporting. Built-in safeguards, like Kontakt.io Secure, protect against hijacking or cloning.
  • Integration with hospital systems: The solution should connect seamlessly with existing infrastructure—EHR/EMR systems, nurse call platforms, facility management software, and analytics dashboards. Open APIs and standards-based architecture are essential.
  • Data-driven insights, not just location: Beyond “dots on a map,” a true partner delivers analytics that drive action—utilization rates, staff workload distribution, patient flow trends, and compliance reports that inform executive decision-making.
  • Support and partnership: Look for providers who act as long-term partners, offering training, support, and continuous innovation. Hospitals need solutions that evolve with changing care models and regulations.
