Industrial Applications

1. Industrial Plant LAN Segmentation with Multi-VLAN Protection

Utilizing the router's support for IEEE 802.1Q VLANs and Layer 3 interfaces, this router segments the industrial floor into isolated operational zones. Sensitive automation equipment and office terminals can reside in isolated broadcast domains, while maintaining the capacity for controlled Layer 3 IP routing to restrict unauthorized cross-network access.

Problem Solved

Mitigates network-wide broadcast storms and prevents lateral cyber security breaches by keeping industrial PLCs, HMIs, and administration networks isolated.

2. Warehouse Logistics AGV Fleet & Scanner Management

Leverages the router's integrated AP management capability to handle the deployment, status monitoring, and configuration of up to 100 wireless APs across a broad warehouse layout. The setup maintains consistent connectivity for high-speed AGVs (Automated Guided Vehicles) and smart barcode scanner systems.

Problem Solved

Reduces network downtime and hardware overhead by eliminating the need for separate wireless controllers while ensuring automated wireless coverage across extensive production facilities.

3. SCADA Control Center Edge Protection & Rogue Device Filtering

Deploys the router as an edge firewall and access management gateway for local SCADA servers. Using strict IP-to-MAC ARP binding and MAC address filtering rules, only recognized server and operator terminals are permitted to request control loop metrics, while blocking external DoS floods and unauthorized scanning.

Problem Solved

Prevents unauthorized edge devices from connecting to the automation network and protects sensitive SCADA control units from malicious Denial of Service (DoS) operations.
