Scientists urge governments to turn old TV frequencies into free “super WiFi”

Governments should sack plans to auction off old television frequencies to the highest bidder and instead use the bandwidth for free super-frequency WiFi if they want to boost the economy, scientists have said.

Old television frequencies are becoming available for other uses around the world, thanks to a switch from analogue to digital transmission.

However, while governments are for the most part auctioning these off to whoever is prepared to pay the most – usually mobile phone networks – they should instead be using the frequencies to create free-to-use, wide-range WiFi, scientists from the Karlsruhe Institute of Technology (KIT) in Germany have said.

This new “super WiFi” would have a far wider range than existing WiFi networks, which are mostly transmitted over wireless local area networks (WLAN) at frequencies of 2GHz or above.

WiFi transmitted over old TV frequencies could be transmitted at lower frequencies than traditional WiFi, resulting in a far wider area covered. This super WiFi’s coverage area could even be as big as several kilometres in radius, a massive improvement on existing networks.

This would mean that pricey mobile services such as 4G were no longer required, which the scientists believe would lead to more mobile internet use, and a wealth of economic benefits.

“Implementation of our approach would have far-reaching consequences,” said Arnd Weber of the Institute for Technology Assessment and Systems Analysis (ITAS) at KIT.

“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.”

In addition to providing direct, measurable cost savings, the technology could, according to the researchers, result in the development of a host of new technologies just as existing WiFi has.

It could also provide direct benefits during disaster scenarios, as a means of providing updates and enabling communication.

However, the big challenge here is convincing governments that this is the right move.

Many have argued they these frequencies are common property and therefore should be made available to the public free of charge, a view that has been opposition from a number of people, including the late Nobel Prize winning economist Ronald Coase.

Coase argued that the frequencies should be auctioned off to ensure they are most effectively used, and the money used by governments to fund other services.

Others have also argued that congestion would make these lower frequency networks unworkable, however Weber and his colleague Jens Elsner argue that it is possible to avoid such congestion with the right technological approach.

Ultimately, convincing governments will be a matter of showing that long-term economic benefits greatly outstrip the short-term financial gains of an auction.

While Weber and Elsner plan to make this case at the UN World Radiocommunication Conference next year, they will no doubt struggle to get many governments onboard.

In the long run, though, those of us living in areas where auctions have gone ahead could find ourselves quite jealous of the countries that choose the super WiFi option.

China planning to end sales of fossil-fuel-powered vehicles

Xin Guobin, China's vice minister of industry and information technology, has said the government is working with regulators to put in place a timetable to end the production and sale of cars powered by fossil fuels. It's hoped the move will accelerate the expansion of the electric car market.

Limited Tesla Autopilot was "partly to blame" for crash

The US National Transportation Safety Board (NTSB) has found that Tesla's Autopilot system was partly to blame for a fatal accident in which a Model S collided with a lorry. The safety board concluded that Tesla allowed the driver to use the system outside of the environment for which it was designed,

Chelsea Manning warns about the risks of AI

During a conversation at Noisebridge hackerspace, Chelsea Manning commented on some of the inherent risks of AI. "We’re now using huge datasets with all kinds of personal data, that we don’t even know what information we’re putting out there and what it’s getting collected for," Manning said.

The plan to make every surface inside the car of the future smart

Yanfeng Automotive Interiors (YFAI) has revealed a vision for the future of cars where every surface inside the vehicle can become a smart surface.

Launched at the International Auto Show, YFAI’s activeSkin concept will turn the largely decorative surfaces inside cars, including the door trim, floor console and instrument panel, into smart interior surfaces, which YFAI says will be “fully interactive” and could be ready by 2022.

“The future generation of surfaces will be smarter than ever. Just by passing your hand over a upholstered surface of the car will appear an interactive surface or dynamic decorative ambient light. Surfaces interact with us, “says Han Hendriks , YFAI’s chief technology officer.

“This technology is impressive.”

YFAI says its customisable 3D glass surfaces could benefit drivers by replacing some of the current operating elements in traditional cars.

However, If no information is called up by the driver, integrated screens and operating surfaces would remain invisible as purely decorative glass surfaces, so drivers would not be distracted by unnecessary information popping up.

“We offer on-demand functionality, so it will only be visible when you need it. In this way we will be able to customise features on interior surfaces,” said Hendriks. “With activeSkin we can achieve a 3D effect that gives a feeling of amazing depth.”

This isn’t the first time YFAI has tried to predict what cars of the future will be like.

The company’s XiM17 concept car was designed with autonomous driving in mind and helped answer the question, “What will people do in their vehicle, if they no longer have to drive?”

YFAI’s XiM17 allows passengers to switch between a number of different modes to allow passengers a number of different ways of engaging.

For example, in family mode all four seats in the car are positioned facing each other, whereas in meeting mode the rear seats are folded away. so that the driver and passenger seats face each other. and a floor console rises to form a desk.
