Europe must open up UWB

Europe will soon be open to ultra-wideband (UWB) networking devices, the European Commission (EC) has said.

The EC gave European markets six months to open up to UWB wireless networking devices. But fewer frequencies will be available for UWB use in Europe than in the US, meaning that vendors will have to tailor their UWB products to the European market.

The Commission gave the 27 member states of the European Union until August to bring their national laws and regulations on the use of radio spectrum into line, to allow the use of UWB devices throughout the EU's market of almost 500 million consumers.

UWB wireless systems spread their high-speed data signal over a wide spectrum of frequencies, but transmit at very low power so as to reduce interference to other signals. The technology could be used to copy large picture files from cameras and phones to printers, or transmitting video between media players and big screens.

Equipment manufacturers have adopted the flavour of UWB championed by the WiMedia Alliance as the radio interface for the next generation of Bluetooth personal area networking devices, and for wireless USB, a cordless replacement for Universal Serial Bus (USB). Just like its wired cousin, wireless USB will transfer data at speeds up to 480Mbps (bits per second) over a distance of 3 metres, although that rate will drop off to 110M bps or less at a distance of 10 metres.

The Commission's announcement follows a decision by the European Radio Spectrum Committee in December that UWB is fit for use in Europe.
