Scientists suggest using television frequencies to create a super Wi-Fi network

German scientists from the Karlsruhe Institute of Technology (KIT) are proposing to use obsolete television radio frequencies for the new Wi-Fi standard. Spreading at lower frequencies than conventional Wi-Fi, the signal will be able to cover large areas - with a radius of up to several kilometers. In cities, this can eliminate the need to support costly 4G networks and increase the mobility and accessibility of the Internet. In addition, in the case of disasters, it can help people not to be left without communication.

In an interview with Factor, Arnd Weber, on behalf of the Institute, explained: “The development of our proposal can lead to great consequences. People, companies, organizations would cease to depend so strongly on mobile networks in the field of information communication. The economic effect would be excellent. ”Where digital television has almost completely replaced outdated analogue, the frequencies are usually simply sold at auction to those who are willing to pay for them. Usually they are bought by companies involved in mobile communications.

Standards of analog television were created in 40-50 years. Digital television is gradually replacing analog - digital has better broadcast quality, more channels are available, additional features are available such as disconnected subtitles and several audio channels, etc. As a result, countries are gradually abandoning analog television and are completely switching to digital broadcasting. The first country, completely switched to the figure, in 2006 became the Netherlands. Russia plans to abandon analogue broadcasting by 2016.
