2198 Westermo's DDW-120 Ethernet extender allows existing twisted pair cables to be used to establish a high-speed remote connection between two Ethernet networks. The company claims this is an easy-to-install alternative to optic-fibre or radio systems when linking remote Ethernet networks.

The device employs a transient blocking unit on each line interface to provide both over-current and over-voltage protection, allowing the line to handle indirect lightning strike transients, power induction and short circuit problems.

The DDW-120 uses twisted pair cables rather than expensive optical fibres or radio links. This plug-and-play unit covers many applications, offering data rates from 192Kbit/s to 5.7Mbit/s in both directions over distances of up to 15km (10 miles).

    The impact of introducing plug-in electric vehicles to the streets of Beijing, one of the world’s most polluted cities, has been examined by researchers from the University of Michigan in the ACS journal Environmental Science and Technology. They use big data mining techniques to understand the impact of fleet electrification. As part of the study, the researchers highlight that while plug-in electric vehicles have developed rapidly in recent years there are still uncertainties with regard to market accepta

    Connecticut’s new administration is using smart policy and ITS solutions to bridge social divides. Andrew Bardin Williams investigates. With only 130,000 residents, New Haven can hardly be called a metropolis. Measuring less than 502km (18 square miles), the city is huddled against the coast, squeezed between two mountains (appropriately called East Rock and West Rock) that, at 111m and 213m (366ft and 700ft) respectively, can hardly be called mountains. The airport is small and has limited service, and th
