A new study shows that old TV frequencies could deliver broader Wi-Fi signals.

Scientists from the Karlsruhe Institute of Technology (KIT) have proposed that old TV frequencies that are no longer being used could deliver Wi-Fi signals to the public which would cost nothing.

The wireless internet, named 'Super Wi-Fi', would broaden the range of existing telecommunications networks by using the old TV frequencies.

Published in the journal Telecommunications Policy, the research shows that by using the frequencies it would increase the short range of our current Wi-Fi devices up to ranges of many kilometres.

KIT says that "The need for the wireless transfer of data will increase significantly in the coming years."

Currently, any old TV frequencies that become free are sold off to the highest bidder, that usual turns out to be a mobile telecomms company.

Arnd Weber, a reasercher at KIT, believes this approach will help the economy: "Implementation of our approach would have far-reaching consequences. Individuals, institutions, and companies would be far less dependent on expensive mobile communications networks in conducting their digital communication. This would also be of great economic benefit.”

Weber proposes that the use of the old frequencies should be discussed at the the World Radiocommunication Conference (WRC) next year. It's a conference organized by the United Nations, where the use of radio frequencies at a global level is decided.
