Traffic Signal Controller Networking: Built to Last Every traffic signal controller depends on a network that can match its demands. When a cabinet-mounted controller sends timing adjustments to traffic lights across dozens of intersections, the data has to move cleanly, quickly, and without interruption. The networking hardware inside that cabinet and along the fiber backhaul is what makes or breaks the entire traffic signal control system.

Federal infrastructure funding comes with binding conditions. Under the Build America, Buy America Act (BABA), any organization receiving federal financial assistance for an eligible infrastructure project must use materials produced in the United States.

A Network Engineer's Guide to Protecting Industrial Infrastructure The hardware and software systems controlling power plants, water treatment facilities, and factory floors were never built with cybersecurity in mind. Operational technology OT was engineered for reliability and physical control — not for a threat landscape where industrial networks face nation-state actors and ransomware gangs.

Intelligent transportation systems (ITS) depend on robust, hardened network infrastructure to deliver real-time data that keeps traffic flowing safely and efficiently. Comnet provides the mission-critical connectivity that powers intelligent transportation systems worldwide, enabling departments of transportation, transit agencies, and municipalities to monitor conditions, manage congestion, and respond rapidly to incidents along roadways and highways.

Electric utilities are the backbone of modern society, powering everything from hospitals to data centers. As the bulk electric system (BES) becomes more interconnected, it faces a growing array of cyber threats, including ransomware, supply chain attacks, and targeted intrusions that can disrupt entire regions. Regulatory oversight is intensifying, and the consequences of non-compliance are more severe than ever.

SCADA systems are the operational backbone of critical infrastructure — power plants, oil and gas pipelines, water treatment facilities, and manufacturing floors all depend on them to monitor and control industrial processes. When SCADA network infrastructure fails, the consequences extend far beyond downtime. For network engineers specifying or hardening OT environments, getting the switch architecture right is non-negotiable.

Intelligent Transportation Systems rely on communication networks that must perform without interruption. IP cameras at intersections, variable message signs along highways, traffic signal controllers, tunnel sensors — the data transmission linking this equipment has direct safety consequences. Choosing the right industrial Ethernet switch is one of the most critical network decisions an ITS engineer makes. The advantages of purpose-built, industrial-grade hardware over commercial alternatives are clear: greater reliability, secure communication, and availability when it matters most. This buyer's guide covers what makes an industrial Ethernet switch suitable for ITS, how managed and unmanaged models compare, the key features to evaluate, and which Comnet switches are purpose-built for transportation deployments.

Power grids are no longer the centralized, one-directional systems they were built to be. The rapid expansion of distributed energy resources, advanced metering infrastructure, and continuous remote monitoring requirements has made the traditional separation between field control systems and enterprise platforms unsustainable. For network engineers and system designers in the energy sector, IT/OT convergence is the defining infrastructure challenge of this decade — and how you architect the underlying network will determine whether your utility capitalizes on it or is constrained by it.

The electric grid that powers homes, businesses, hospitals, and essentially modern society depends on a foundation of security, reliability, and resilience. To help safeguard that foundation, the North American Electric Reliability Corporation (NERC) enforces a comprehensive set of regulations called NERC CIP — Critical Infrastructure Protection standards.
