Indiana DOT uses Proxim Wireless for statewide ITS project

Provider of indoor and outdoor wireless broadband ecosystems, Proxim Wireless Corporation, has announced that the Indiana Department of Transportation (INDOT) has deployed an end-to-end Proxim wireless network for a statewide Intelligent Transportation System (ITS). The wireless network connects traffic and video components over hundreds of square miles throughout the northwest Indiana and Indianapolis areas. Initially, INDOT had evaluated several competing wireless technologies, but the autonomous operation of Proxim’s MP11 5054 and 5012 series radios performed better and offered greater value than the other systems.

The new wireless system enables the following traffic-related applications: traffic management, where residents of Indiana and Illinois can visit INDOT's TrafficWise website to get real-time traffic updates, as well as visual images of the roads they are traveling, with images provided by video cameras connected wirelessly via Proxim’s unlicensed WiMAX radios, the Tsunami MP11 5054; VMS (Variable Message Signs) along Indiana’s highways are wirelessly connected to the wireless network via Tsunami MP11 5012 subscriber units, which enables the immediate updating of the signs to warn drivers of road conditions, accidents, detours and Amber Alerts; solar-powered traffic detection radar sites that detect the flow of traffic and warn drivers of slow conditions ahead, which due to the low power consumption of the Tsunami MP11 5012 subscriber units, can be powered via solar panels; seamless connectivity to INDOT’s two traffic management centers (TMCs) via high-performance wireless backhaul links, which saves the state millions of dollars in upfront deployment costs by not requiring the use of fiber to connect all components; wireless remote management, which allows engineers to access the network via Wi-Fi using Proxim’s ORiNOCO AP-4000 MR-LR.

To roll out the ITS network, Proxim partnered with Meade Electric of Illinois, to handle the integration of more than 600 radios, including all of the tower and electrical work. Troy Boyd, INDOT’s ITS technology deployment division director, says, “When we began rolling out this statewide Intelligent Transportation System, we knew that the cost to connect the hundreds of components via fiber would be completely cost-prohibitive. With Proxim’s end-to-end wireless solutions, we were able to deploy a single network consisting of wireless backhaul, unlicensed WiMAX and Wi-Fi that enabled us to connect and manage the entire ITS. As a result, we are able to deliver mission-critical traffic services to the citizens of Indiana in a fiscally responsible manner.”
