Industrial Applications

1. Redundant Uplink Gateway for Cloud-Monitored Manufacturing Plants

Industrial control rooms require constant connectivity with centralized databases and cloud monitoring systems. Using the TL-ER6220G's 3 configurable WAN/LAN ports, plants can link multiple ISP internet connections to prevent downtime.

Problem Solved

Mitigates high-cost operational downtime by providing automatic line-backup failover and policy routing, redirecting traffic instantaneously if a primary fiber line fails.

2. Secure Site-to-Site VPN Tunneling for Remote Warehousing and Logistics

Distributed distribution hubs must transmit critical inventory data to headquarters securely. Utilizing its dual-core 1GHz MIPS 64-bit processor, this router manages up to 200 concurrent secure IPSec VPN tunnels between corporate offices and storage depots.

Problem Solved

Secures data transfers without the overhead of standalone VPN hardware, delivering low-latency encryption that protects enterprise logistics data from external inspection.

3. Unified Wireless Network Control in Large-Scale Assembly Facilities

Automated factories use handheld barcode scanners and automated guided vehicles (AGVs) requiring seamless Wi-Fi roaming across multiple access points. The built-in wireless AC controller inside this router unifies management of up to 150 enterprise APs.

Problem Solved

Eliminates complex manual configurations and extra hardware controllers by providing automatic AP discovery, zero-config deployment, and central status monitoring for smooth plant-wide wireless operations.
