How to Choose the Right RTLS Platform: Moving Beyond Basic Asset Tracking

Real-Time Location Systems (RTLS) have evolved from basic asset visibility tools into core infrastructure for modern healthcare operations. Today, RTLS supports patient flow optimization, staff coordination, asset utilization, and the foundation for Smart Clinics and Smart Hospitals.

At Sentrax, we focus exclusively on Bluetooth Low Energy (BLE)-based RTLS, engineered to deliver reliable, clinical-grade outcomes—without the complexity and cost associated with proprietary positioning technologies.

1. Accuracy: Delivering the Right Precision for Healthcare Workflows

Hospitals and clinics require room-level and near-room-level accuracy to enable high-impact operational and clinical workflows, including:

• Reduced patient wait times through better visibility of patient and asset movement
• Improved room availability awareness to support smoother patient flow and faster room turnover
• Faster staff response times by knowing the real-time location of people, equipment, and critical assets
• Enhanced clinical workflow efficiency by minimizing delays caused by missing equipment or unclear room status

Among widely adopted indoor positioning technologies, BLE Angle of Arrival (AoA), advanced Wi-Fi positioning, and UWB are recognized for their ability to deliver high accuracy.

Sentrax leverages BLE AoA to achieve near-room and sub-meter accuracy, making it highly effective for clinical environments—without introducing non-standard or proprietary radio technologies.

For broader coverage and cost efficiency, BLE RSSI-based positioning is used where room-level or zone-level visibility is sufficient.

2. BLE AoA: High Accuracy Without System Complexity

Some RTLS platforms rely on specialized radio technologies that increase:

• Deployment complexity
• Hardware costs
• Long-term system rigidity

Sentrax’s BLE AoA-based RTLS delivers high accuracy using a widely adopted, standards-based technology. BLE AoA allows healthcare organizations to achieve precise indoor positioning while benefiting from:

• Lower-cost, widely available BLE tags
• Flexible hardware options
• Easier system expansion as needs evolve

The result is high-performance RTLS without vendor lock-in.

3. Purpose-Built BLE RTLS for Healthcare Environments

Achieving consistent room-level accuracy with BLE requires more than hardware—it requires advanced location intelligence software.

Sentrax’s Solix RTLS platform is facilities, where:

• Clinical environments are dynamic and constantly changing
• Equipment, staff, and patient movement must be tracked without disrupting care delivery
• Location accuracy must remain consistent and dependable across departments and floors
• Real-time visibility is required to support smooth workflows and faster decision-making
• This ensures healthcare teams can rely on location data as operational intelligence, not just raw positioning information.

By combining BLE AoA, RSSI intelligence, and healthcare-aware algorithms, Sentrax delivers stable, repeatable positioning outcomes across real-world clinical environments.

4. Lower Cost of Ownership, Better Long-Term Value

Sentrax’s BLE RTLS platform is engineered to deliver high accuracy with long-term cost efficiency, enabling healthcare organizations to scale without financial strain.

Sentrax delivers:

• Cost-effective BLE tags with extended battery life, reducing frequent replacements.
• High-performance Sentrax BLE scanners and gateways designed for continuous, reliable operation in clinical environments.
• Reduced maintenance effort through centralized device management and remote configuration
• Scalable deployments that expand room-by-room or department-by-department—without heavy upfront investment.

By combining efficient BLE tags with purpose-built scanners, gateways, and intelligent software, Sentrax ensures lower total cost of ownership (TCO) while maintaining the accuracy and reliability required for healthcare workflows.

5. Smart Clinics & Smart Hospitals: RTLS as a Digital Foundation

Modern healthcare facilities are moving toward data-driven, automated operations.

Sentrax’s BLE RTLS platform acts as a real-time location data backbone, enabling:

• Workflow automation
• Smart alerts and analytics
• Seamless integration with healthcare and building systems

By relying solely on BLE technology, Sentrax ensures RTLS remains interoperable, scalable, and future-ready.

Final Takeaway: BLE AoA Done Right Delivers Real Clinical Outcomes

RTLS success is not defined by the radio technology alone—it is defined by outcomes, reliability, and scalability.

With Sentrax, healthcare organizations gain:

• Near-room and sub-meter accuracy using BLE AoA
• Scalable room-level visibility using BLE RSSI
• Lower complexity and cost through a BLE-only architecture
• A future-ready platform for Smart Clinics and Smart Hospitals

Sentrax helps healthcare teams move beyond asset tracking and toward intelligent, real-time operational insight—powered entirely by BLE.
