CALABASAS, Calif. -- Strix Systems today announced that state-run Korean Highway Corp. (KHC) selected Strix Access/One® Outdoor Wireless System (OWS) as the winner for the intelligent highway infrastructure test bed, the multi-phase, multi-year nationwide highway project between Korea’s two largest cities of Seoul and Pusan.

The purpose of the projects is to determine a cost effective method, in contrast to legacy cellular services, for Korea’s intelligent, interactive, digital highway infrastructure to deliver multimedia applications to a wide range of end-user, vehicular and other Wi-Fi enabled devices. The system will enable the delivery of video surveillance and voice streamed to and from public safety and commuter vehicles and provide the architecture for a simplified communications infrastructure for traffic control and related systems.

The test bed is located on the Kyungbu highway at a 31 kilometer stretch between Pangyo and Osan. Key criteria for the tests included the ability to achieve continuous fluid 8 Mbps end-to-end connections for streaming video, voice over IP and multimedia applications at speeds reaching 100 km/hour.

TTA, Korean public standard organization, hosted the benchmark tests performed by WLAN highway project of Korean Highway Corp. All major wireless/Wi-Fi mesh network equipment manufacturers have been represented. Broadwave Inc., a Strix Systems distributor in Korea, working closely with its partners POSDATA and Hyundai HDS, submitted Strix Systems Access/One OWS for the evaluation.

Strix OWS wireless mesh nodes were installed every 1 km with an average 3 or 4 hops from wired backhaul and mobile mesh nodes were installed in vehicles. The test results proved Strix Access/One wireless mesh network equipment yielded the highest performance over any competitor with the highest throughput, lowest latency and continuous robust performance successfully exceeding the base-line results which were not achieved by any other manufacturer. In fact, Strix Access/One OWS achieved more than double the backhaul throughput of any vendor at 18Mbps over 4 hops while the moving vehicle tests also proved Strix Systems ability to maintain an average high-density megapixel video streaming of 8~10 Mbps at not only the defined maximum test threshold of 100km/h, but exceeding 180km/h.

“We have not seen such a large area deployment of wireless mesh network with WLAN technology in the world,” said Kim, Hongchol, Manager, Korean Highway Corp. “The main application of this project is to monitor real, local highway road status and to transfer it to drivers in real time through these mesh network.”
