GAO’s Cloud-based Smart Patient Tracking System
GAO’s Cloud-based Smart Patient Tracking System enhances hospital automation, clinical oversight, and real-time patient visibility using advanced IoT wireless technologies such as BLE, RFID, Wi-Fi HaLow, UWB, LoRaWAN, Zigbee, NB-IoT, Cellular IoT, and GPS-IoT. This cloud-supported platform creates a unified digital patient-locator ecosystem that helps healthcare facilities manage patient flow, monitor movement, strengthen safety protocols, and streamline staff coordination. The cloud provides resilience, high-availability compute clusters, elasticity for large hospitals, and secure multi-site data synchronization.
Patient-worn tags, wristbands, room-level sensors, care-unit gateways, and mobile clinical stations communicate with GAO’s cloud microservices to deliver continuous location telemetry, alert conditions, workflow logs, and safety indicators. With headquarters in New York City and Toronto and four decades of R&D excellence, GAO delivers reliable, enterprise-grade tracking solutions trusted by hospitals, government health agencies, research centers, and emergency care providers across the U.S., Canada, and internationally.
Cloud Architecture of GAO’s Cloud-based Smart Patient Tracking System
GAO’s cloud architecture is designed for clinical-grade monitoring, real-time visibility, and secure data management. IoT devices using BLE, RFID, Wi-Fi HaLow, UWB, LoRaWAN, Zigbee, NB-IoT, Cellular IoT, and GPS-IoT communicate with gateways installed in wards, hallways, diagnostic areas, operating theaters, and emergency zones.
Major architectural layers include
- Patient Tagging & Sensing Layer: Wearable BLE or RFID wristbands, UWB location tags, LoRaWAN trackers, Zigbee room beacons, and GPS-IoT devices capture patient identity, proximity, movement, and safety indicators.
- Edge Monitoring Layer: Ward-level gateways, hallway receivers, and care-unit controllers apply signal filtering, distance estimation, device authentication, and packet buffering for unstable environments.
- Cloud Transport Layer: Encrypted MQTT/HTTPS channels move event streams to the cloud with QoS control, timestamp alignment, and tamper-prevention safeguards.
- Cloud Processing Layer: Microservices hosted in containerized clusters perform location triangulation, event correlation, geofencing analysis, workflow timing, emergency alert triggering, and predictive analytics.
- Clinical Data Repository: Multi-region encrypted data storage maintains patient mobility histories, alert logs, compliance records, and facility-wide operational insights.
- Healthcare Operations Portal: Dashboards used by nurses, physicians, administrators, and safety officers for real-time monitoring, escalation handling, analytics, and route tracing.

Local Server Version of GAO’s Smart Patient Tracking System
A local-server configuration enables healthcare facilities to manage patient tracking, geofencing logic, and alert processing entirely on-premise. This option is well-suited for hospitals requiring air-gapped environments, high-security departments, or restricted network policies. GAO provides hybrid and offline-capable modes, ensuring continuous location monitoring, alarms, and workflow logging even when external connectivity is unavailable.
