Comparison: RFID vs BLE vs Hybrid RFID–BLE

RFID-Only Systems

• Optimized for rapid bulk scanning of racks, trays, and storage shelves
• Supports high-density reading in accessioning and inventory workflows
• Ideal for fixed-location identification and freezer inventory audits
• No continuous beaconing; location updates occur during scans

BLE-Only Systems

• Suitable for real-time sample localization, movement telemetry, and ambient condition broadcasting
• Excellent for mobile assets such as sample carts, cryogenic shippers, and transport carriers
• Lower read density than RFID but offers persistent signal monitoring

Hybrid RFID–BLE Systems

• Combines rapid mass-reading with continuous real-time position tracking
• Ideal for complex labs requiring both bulk authentication and live telemetry
• Provides redundancy, optimized zone coverage, and maximum process visibility
• Recommended for enterprise-scale facilities handling thousands of daily specimens

Local Server Version for On-Premise Deployment

A local-server deployment of GAO’s lab sample tracking system operates within the facility’s secure on-premise network. The setup includes internal RFID readers, BLE gateways, database servers, synchronization engines, and LIS middleware connectors running behind enterprise firewalls. This version is suitable for laboratories requiring strict data residency controls, air-gapped networks, or enhanced protection for sensitive R&D or government projects. GAO configures the system using ruggedized industrial controllers and provides onsite calibration, firmware updates, reader tuning, and network optimization support.

Cloud Integration and Data Management Architecture

GAO offers cloud-based hosting for Lab Sample Tracking Systems with scalable microservices, distributed data pipelines, secure API endpoints, and role-based access management. Technicians, supervisors, auditors, and QA managers gain real-time dashboards, audit trails, exception alerts, freezer-mapping visualizations, and automated compliance reporting from any authorized location. The cloud platform synchronizes RFID interrogation events, BLE telemetry, storage-location changes, user-authenticated actions, and environmental sensor data into a unified dataset. GAO’s cloud environment supports encrypted transmission, multi-region redundancy, automated backups, and cross-site analytics across global laboratory networks.
