Wireless data transmission: researchers want TV frequencies for wireless use – Handelsblatt

Karlsruhe Vacant television channels should be used in the future for a proposal from the science of wireless networks for data transmission for all. The sociologist Arnd Weber from the Karlsruhe Institute of Technology (KIT) and the network technology expert Jens Elsner of the Munich Innovation Group suggested in a study published by the journal “Telecommunications Policy” study to use specific TV frequencies as common for extended wireless networks instead of auctioning of wireless providers.

The wireless networks are usually assigned to high frequencies from 2 GHz. There, however, the range is usually limited to the rooms of a house. Lower TV frequencies, as in the so-called UHF band 470-790 MHz were previously used primarily for the transmission of TV signals. With the trend toward Internet-TV (IPTC) but they are increasingly less needed.

The lower frequencies have for wireless the advantage that wireless data transmission much better with obstacles such as walls cope. Existing wireless networks could achieve a range of several kilometers. This offers new opportunities for public wireless networks in cities, which are freely accessible to all.

“The realization of our approach would have far-reaching consequences, “said Weber of the Institute for Technology Assessment and Systems Analysis (ITAS) of the KIT. “Individuals, institutions and companies would rely on their digital communication to a much lesser extent on expensive mobile networks.”

The two authors refer to a statement by the KIT from the Monday before, their approach on the agenda of the World Radiocommunication Conference (WRC) set. This was initiated by the United Nations Conference decides on the global use of radio frequencies.
