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.

Police want to 3D print a dead man's fingers to access his phone

Law enforcement officers have asked a professor at Michigan State if he can help unlock a murder victim's phone. The police want the professor to reproduce the victim’s fingerprint from a prerecorded scan, which could be then used to unlock the phone.

Lampposts and churches will recharge Amazon's fleet of drones

Amazon has been awarded a patent for "docking stations" so its delivery drones can be built on tall structures such as lampposts or churches. The stations will allow the unmanned machines to recharge before they continue delivering up packages.

Are we 10 years away from finding life outside our Solar System?

Astronomers have said that discovery of life outside our solar system could be just 10 years away after they found further evidence of two “precious” exoplanets are similar to Earth. The astronomers say the planets are "rocky" just like Mars, Venus or Earth,

VR wants to remind us that it’s the king of immersive technology

It seems that augmented and virtual reality are always having to compete with one another. Right now, thanks to Pokemon Go, AR is in the ascendancy, but a prototype architecture tool could be about to strike a blow for VR.

DesignSpace has been developed for the HTC Vive to enable architects and designers to draft concepts in virtual reality, as well as allowing colleagues to work together in a shared virtual space.

While DesignSpace is just a prototype at the minute it could be an amazing tool for architects, and shows that both AR and VR have an exciting future.

Elon Musk has already disrupted the automotive industry. Now he plans to do it again

Elon Musk has announced that he is at the end of the first stage of his Tesla Motors masterplan, and is anxious to get on with stage two.

Despite the technology mogul finding himself under pressure in recent weeks, following the death of a driver in a self-driving Tesla car, Musk has found time to publicly announce his ‘Master Plan, Part Deux’.

In response to the death of Joshua Brown in a Tesla Model S, Musk’s revamped masterplan includes an ambition to “develop a self-driving capability that is 10 times safer than manual via massive fleet learning”.

“As the technology matures, all Tesla vehicles will have the hardware necessary to be fully self-driving with fail-operational capability, meaning that any given system in the car could break and your car will still drive itself safely,” wrote Musk in a blog post.

Musk has also pointed out why Tesla is deploying partial autonomy now even though it has come in for criticism in recent weeks.

“The most important reason is that, when used correctly, it is already significantly safer than a person driving by themselves and it would therefore be morally reprehensible to delay release simply for fear of bad press or some mercantile calculation of legal liability,” said Musk.

The other three achievements Musk is looking to make in stage two of his plan to accelerate the advent of sustainable energy are: to create solar roofs with seamlessly integrated battery storage, to expand the electric vehicle product line to address all major segments and to enable your car to make money for you when you aren’t using it.

To achieve the first point Musk plans to merge Tesla with his other sustainable energy company, SolarCity, as they are in “pursuit of the same overarching goal of sustainable energy”.

Musk imagines the second point, of expanding the electric vehicle product line, will be achieved by introducing a fleet of autonomous buses that can accommodate wheelchairs, strollers and bikes.

It’s in  the third point though where Musk has told of his plans to disrupt the automotive industry as we know it.

Musk wants to develop a Tesla shared fleet where cars can generate income for their owners while they work or are on vacation.

“Since most cars are only in use by their owner for 5% to 10% of the day, the fundamental economic utility of a true self-driving car is likely to be several times that of a car which is not,” said Musk.
