BLE and RFID-based Production Line Automation and Job Routing System

BLE and RFID-based Production Line Automation and Job Routing System from GAO provides a fully integrated digital framework to identify, monitor, and route workpieces and jobs across manufacturing floors. TheSYSTEM uses RFID-only deployments when precise, high-speed part verification is required, BLE-only deployments for continuous location and proximity monitoring, or hybrid BLE+RFID deployments for real-time tracking with high-accuracy identification. GAO’s solution leverages encoded tags, geofencing, beacon telemetry, and event-driven workflows to prevent misrouting, optimize line balance, and enable deterministic job sequencing. Manufacturing engineers, line supervisors, and operators gain full visibility of work-in-progress (WIP) status, job priorities, and machine allocation. With GAO headquartered in New York City and Toronto, Canada, our four decades of R&D investment, quality assurance, and expert onsite/remote support ensure reliable deployment across high-mix assembly lines, robotic cells, and manual production stations.

Description, Purposes, Issues Addressed, and Benefits of GAO’s BLE and RFID-based Production Line Automation and Job Routing System

How GAO’s System Works

• Reduced scrap, rework, and unplanned downtime.
• Enhanced operator and tool utilization tracking.
• Seamless integration with existing MES, ERP, and PLC infrastructure.
• Backed by GAO’s four decades of engineering expertise, quality assurance, and dedicated support.

Comparison: RFID Alone vs BLE Alone vs Hybrid BLE+RFID

RFID Alone

• Provides precise, high-speed identification at defined checkpoints.
• Supports bulk reading of pallets, totes, or fixture-mounted parts.
• Ideal for deterministic routing and validation at line-side gates.

BLE Alone

• Enables continuous proximity monitoring and location tracking.
• Delivers ambient telemetry for operator presence, buffer queues, and line flow.
• Best suited for dynamic workflows requiring ongoing WIP awareness.

Hybrid BLE+RFID

• Combines checkpoint identification accuracy with continuous movement and condition tracking.
• Ideal for complex, high-mix production floors with mixed automation levels.
• Facilitates predictive analysis, load balancing, and workflow optimization.
