Industrial Applications

1. Multi-WAN Link Aggregation and Failover for Manufacturing Facilities

Factories rely on constant cloud and server connectivity for SCADA and MES database logging where a single ISP failure halts production. Utilizing the TL-ER3229G, engineers can configure up to 4 separate ISP links for seamless routing and redundancy.

Problem Solved

Prevents factory network downtime by utilizing 3 configurable WAN/LAN ports alongside the dedicated WAN port, allowing the router to automatically reroute critical industrial telemetry traffic if the primary ISP link fails.

2. Secure Remote Monitoring and Maintenance of Distributed Machinery (VPN Tunneling)

Machine builders and industrial system integrators need to securely access on-site PLC networks across different branch factories or remote municipal utility plants without exposing data to the public internet.

Problem Solved

Provides dedicated hardware VPN acceleration supporting up to 50 IPSec and 32 L2TP/PPTP tunnels, allowing engineers to establish highly secure, encrypted site-to-site tunnels directly to the remote factory floors for safe remote programming.

3. Campus-Wide Industrial AP Management and Network Isolation for Warehouse Logistics

Large warehouses require seamless Wi-Fi coverage for AGVs (Automated Guided Vehicles) and barcode scanners, but also need strict network segmentation to keep critical operational assets isolated from guest and office traffic.

Problem Solved

Leverages the built-in AC controller to manage up to 100 enterprise APs alongside IEEE 802.1Q VLAN support, enabling engineers to segment the logistics network to isolate mission-critical AGV telemetry and prevent broadcast storm degradation.
