GAO’s RFID Bluetooth Hybrid Systems Overview Using RFID Technologies

RFID Bluetooth Hybrid Systems combine RFID technologies, including UHF, HF, NFC, and LF, with Bluetooth Low Energy (BLE) to deliver enhanced asset tracking, identification, and monitoring across enterprise environments. These hybrid systems integrate the automated data capture of passive and semi-passive RFID tags with the proximity sensing, real-time notifications, and connectivity of BLE devices.

The system supports multiple deployment options, including cloud-based management platforms and non-cloud configurations running on handheld computers, PCs, local servers, or remote servers. This flexibility allows organizations to optimize latency, regulatory compliance, and operational scalability. The architecture ensures real-time asset visibility, automated event logging, and secure data access while seamlessly integrating with enterprise resource planning (ERP), manufacturing execution systems (MES), and other operational technologies. GAO leverages decades of experience to deliver these hybrid systems with expert support, ensuring operational continuity and performance optimization.
