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 Finnish Meteorological Institute is currently testing two-way delivery of local weather data as Timo Sukuvaara explains. Road weather information is one of the key ways in which ITS can help reduce traffic accidents and fatalities – which is why the Finnish Meteorological Institute (FMI) has long provided road weather services. Now, the CoMoSeF (Cooperative Mobility Services of the Future) project has been developing communication methodologies to deliver road weather services directly to vehicles and g
