BLE AoA-based RTLS systems are the best choice for most hospitals.
They provide sub-meter accuracy, low latency, and long battery life, making them suitable for tracking patients, staff, and medical equipment across large facilities. Compared to UWB and Wi-Fi, BLE AoA offers the best balance of performance and scalability.
RTLS accuracy ranges from 0.1 meters to 10 meters depending on the technology used.
UWB and BLE AoA can achieve sub-meter accuracy (0.1–1 meter), while Wi-Fi-based systems typically provide 3–10 meters accuracy. The required accuracy depends on the use case, such as surgical tracking versus general asset monitoring.
An RTLS system consists of tags, anchors (or gateways), and a location engine.
Tags emit signals, anchors receive them, and the location engine calculates positions using algorithms like AoA or RSSI. This architecture enables continuous real-time tracking within a defined space.
Modern RTLS solutions are designed for scalable and manageable deployment.
BLE-based systems require moderate infrastructure setup but are easier to scale compared to UWB. Advanced providers like Blueiot simplify deployment with optimized calibration and configuration tools.
RTLS provides real-time continuous tracking, while RFID typically offers point-in-time identification.
RTLS systems actively monitor location changes, whereas RFID systems usually detect items only when scanned or within a specific zone. RTLS is more suitable for dynamic healthcare environments.
The best RTLS solution for healthcare tracking is BLE AoA due to its optimal balance of accuracy, scalability, and efficiency.
Healthcare organizations should prioritize RTLS systems that deliver sub-meter accuracy, low latency, and long battery life. BLE AoA-based solutions, such as those provided by Blueiot, offer reliable performance in complex hospital environments and are well-suited for large-scale deployment.
