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.

Robot takes first steps towards building artificial lifeforms

A robot equipped with sophisticated AI has successfully simulated the creation of artificial lifeforms, in a key first step towards the eventual goal of creating true artificial life.

The robot, which was developed by scientists at the University of Glasgow, was able to model the creation of artificial lifeforms using unstable oil-in-water droplets. These droplets effectively played the role of living cells, demonstrating the potential of future research to develop living cells based on building blocks that cannot be found in nature.

Significantly, the robot also successfully predicted their properties before they were created, even though this could not be achieved using conventional physical models.

The robot, which was designed by Glasgow University’s Regius Chair of Chemistry, Professor Lee Cronin, is driven by machine learning and the principles of evolution.

It has been developed to autonomously create oil-in-water droplets with a host of different chemical makeups and then use image recognition to assess their behaviour.

Using this information, the robot was able to engineer droplets to have different properties­. Those which were found to be desirable could then be recreated at any time, using a specific digital code.

“This work is exciting as it shows that we are able to use machine learning and a novel robotic platform to understand the system in ways that cannot be done using conventional laboratory methods, including the discovery of ‘swarm’ like group behaviour of the droplets, akin to flocking birds,” said Cronin.

“Achieving lifelike behaviours such as this are important in our mission to make new lifeforms, and these droplets may be considered ‘protocells’ – simplified models of living cells.”

The research, which is published today in the journal PNAS, is one of several research projects being undertaken by Cronin and his team within the field of artificial lifeforms.

While the overarching goal is moving towards the creation of lifeforms using new and unprecedented building blocks, the research may also have more immediate potential applications.

The team believes that their work could also have applications in several practical areas, including the development of new methods for drug delivery or even innovative materials with functional properties.

Mac spyware stole millions of user images

A criminal case brought against a man from Ohio, US has shed more light on a piece of Mac malware, dubbed Fruitfly, that was used to surreptitiously turn on cameras and microphones, take and download screenshots, log keystrokes, and steal tax and medical records, photographs, internet searches, and bank transactions from users.

Las Vegas strip club employs robot strippers

A Las Vegas strip club has flown in robot strippers from London to 'perform' at the club during CES. Sapphire Las Vegas strip club managing partner Peter Feinstein said that he employed the robots because the demographics of CES have changed and the traditional female strippers aren’t enough to lure a crowd to the club anymore.

Scientists discover ice cliffs on Mars

Using images provided by the Mars Reconnaissance Orbiter, scientists have described how steep cliffs, up to 100 meters tall, made of what appears to be nearly pure ice indicate that large deposits of ice may also be located in nearby underground deposits. The discovery has been described as “very exciting” for potential human bases.
