Case Study: Metropolitan City in Nebraska achieves resilient, high‑bandwidth traffic management with Advantech’s industrial networking solution

Implementing an Advanced Traffic Management System with Advantech’s Industrial Networking Solution

Metropolitan City in Nebraska faced an aging field network with insufficient bandwidth, no fiber-based redundancy between intersections, and endpoint devices that lacked PoE+ power — all barriers to deploying an advanced traffic management system. The city engaged Advantech to provide an industrial networking solution, centered on the EKI-7712G-4FPI L2 managed Ethernet switches plus SFP modules and DIN-rail power supplies to meet traffic-grade environmental and power needs.

Advantech deployed EKI-7712G-4FPI switches to deliver full Gigabit per port connectivity, multi-mode and single-mode SFP uplinks (short- and long-reach), L2 features for VLAN and redundancy, and PoE+ support (up to 30 W per device with 240 W PSE capacity) to power cameras and radios. Advantech’s solution passed environmental and traffic POC tests, established a resilient fiber ring across intersections, improved overall traffic-network performance, and enabled a smooth system upgrade backed by on-site consultancy and timely support.
