How ADOT Connects Arizona's Highways with Enable-IT Ethernet and PoE Extenders<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Arizona’s highways cross some of the harshest terrain in the country. Interstates run from the Sonoran Desert through high-country forests, past border crossings and into one of the fastest-growing metro areas in the United States. Summer pavement temperatures can top 150\u00b0F, and northern Arizona sees snow and ice every winter.<\/p>

The Arizona Department of Transportation (ADOT) manages this network with sensors, cameras and connected equipment that must report back reliably from remote locations. Most of those devices sit far from the nearest network switch.<\/p>

Standard Ethernet and Power over Ethernet (PoE) stop at 100 meters (328 feet). Enable-IT Ethernet Extenders and PoE Extenders carry high-speed data, and power, far beyond that limit over existing copper cable. Inside ADOT facilities, Enable-IT 8805 PoE Switches power the security cameras and access control systems that protect staff and equipment.<\/p>

Here is how it works, from the roadside to the office.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Roadside sensors<\/h4>

ADOT’s Intelligent Transportation Systems (ITS) rely on vehicle detectors, traffic counters, ramp meters, weather stations and dynamic message signs. These devices feed the data that helps ADOT manage congestion in Phoenix and Tucson and warn drivers about dust storms, heat and winter weather in rural areas.<\/p>

Many of these sites are hundreds or thousands of feet from a controller cabinet. Enable-IT Ethernet Extenders carry sensor data over existing twisted-pair copper, so older sites can join the IP network without trenching new fiber across the desert.<\/p>

Traffic cameras<\/h4>

ADOT’s traffic operations center depends on live camera feeds to confirm crashes, clear incidents and keep drivers informed. Pan-tilt-zoom (PTZ) IP cameras on poles and overpasses need both bandwidth and power.<\/p>

Enable-IT PoE Extenders send data and PoE power to each camera over a single cable, well past the 100-meter limit. That means no separate power supply at the top of the pole. Outdoor-rated models such as the Enable-IT 865W PRO Outdoor PoE Extender are built for sealed roadside cabinets in extreme heat.<\/p>

Enforcement and highway safety cameras<\/h4>

Arizona has no toll roads, but its highways still depend on cameras that capture vehicles around the clock. Commercial vehicle ports of entry use license plate readers and inspection cameras to screen trucks entering the state. Wrong-way driver detection systems use cameras and sensors along freeway ramps to spot drivers going the wrong way and alert authorities within seconds.<\/p>

These systems cannot afford a dropped link. Enable-IT extenders provide steady, low-latency connections from gantry and ramp-mounted cameras back to roadside equipment, even where fiber is unavailable or too costly to reach a single site.<\/p>

The result for ADOT:<\/strong> more devices online, faster upgrades on existing cable and dependable data in conditions that push ordinary network gear past its limits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

ADOT’s district offices, maintenance yards and operations centers need the same protection as any critical public facility. Security cameras watch entrances, parking lots and equipment yards. Access control readers, door controllers and electric locks decide who gets in.<\/p>
