Backhauling Surveillance Video for Transportation Networks over Wireless Infrastructure

Megapixel video cameras have become critical tools in regulating highway traffic and detecting and responding to road accidents in real time.

The rapid evolution to IP-based cameras, which require higher resolution and frame rates, as well as the capacity to support advanced analytics, demand an infrastructure capable of transporting the large amount of high-speed data that is generated. Because it is often impractical, if not prohibitively expensive, to lay fiber optic infrastructure along the entire route, transportation planners and highway administrators can opt for a cost-effective wireless solution to backhaul extensive video applications to the traffic control center.

A wireless access solution for connecting multiple cameras over a single network, however, has to be expert enough to transmit highly focused video across different terrains and locations. Engineered to meet requirements as stringent as these, the Airmux series of wireless multiplexers from RAD Data Communications has become the leading wireless transmission solution for transporting high quality video over extended distances. Its high bandwidth and low latency enable traffic control centers to monitor highways and take immediate action when required.

With a net payload throughput of up to 50 Mbps and a maximum transmission distance of up to 120 kilometers (75 miles), the Airmux is a carrier-class, point-to-point and multi point-to-point wireless transmission system. Its flexible, scalable architecture responds perfectly to the demands of the highway environment while providing license-plate recognition accuracy. The future-proof Airmux features a robust, high-quality radio link that connects Ethernet between two sites. It saves on operating expenses (OpEx) because it is cost-optimized for video surveillance with asymmetric Ethernet bandwidth support. Its high quality, robust radio link is ideal for surmounting high-interference scenarios posed by changing highway landscapes.

The Airmux transmits over licensed 2.5 GHz BRS bands or over unlicensed, sub-6GHz bands, an option that enables immediate deployment. In addition, multiple point-to-point architecture allows a dedicated bandwidth to be assigned to each point-to-point link. Transmission is encrypted to ensure security.

The easy to install and maintain Airmux is a must for highway applications in which dozens or even hundreds of units have to be connected in a minimal amount of time in order to be effective. It also operates flawlessly even in extreme temperatures of up to -30 degrees Celsius (-22 Fahrenheit).
