Washington: A team of US Engineers which included and Indian origin researcher demonstrated that it is possible to generate Wi-Fi transmissions using 10,000 less power than conventional methods. This is an attempt to save more energy while playing games and doing other things that eat more energy.

The new “Passive Wi-Fi” system also consumes 1,000 times less power than existing energy-efficient wireless communication platforms, such as Bluetooth Low Energy and Zigbee, said computer scientists and electrical engineers from the University of Washington.

“We wanted to see if we could achieve Wi-Fi transmissions using almost no power at all. That is basically what ‘Passive Wi-Fi’ delivers. We can get Wi-Fi for 10,000 times less power than the best thing that’s out there,” said study co-author Shyam Gollakota, assistant professor of computer science and engineering.

“Passive Wi-Fi” can for the first time transmit Wi-Fi signals at bit rates of up to 11 megabits per second that can be decoded on any of the billions of devices with Wi-Fi connectivity. These speeds are lower than the maximum Wi-Fi speeds but 11 times higher than Bluetooth. Apart from saving battery life, wireless communication that uses almost no power will help enable an “Internet of Things” reality where household devices and wearable sensors can communicate using Wi-Fi without worrying about power.

“All the networking, heavy-lifting, and power-consuming pieces are done by the one plugged-in device. The passive devices are only reflecting to generate the Wi-Fi packets, which is a really energy-efficient way to communicate,” explained co-author Vamsi Talla, an electrical engineering doctoral student. To achieve such low-power Wi-Fi transmissions, the team essentially decoupled the digital and analog operations involved in radio transmissions.

The Passive Wi-Fi architecture assigns the analog, power-intensive functions – like producing a signal at a specific frequency — to a single device in the network that is plugged into the wall. An array of sensors produces Wi-Fi packets of information using very little power by simply reflecting and absorbing that signal using a digital switch.

In real-world conditions on the university campus, the team found the passive Wi-Fi sensors and a smartphone can communicate even at distances of 100 feet between them. Because the sensors are creating actual Wi-Fi packets, they can communicate with any Wi-Fi enabled device right out of the box. “Our sensors can talk to any router, smartphone, tablet or other electronic device with a Wi-Fi chipset,” noted electrical engineering doctoral student Bryce Kellogg.

The technology can enable entirely new types of communication that haven’t been possible because energy demands have outstripped available power supplies. It could also simplify our data-intensive worlds. “Now that we can achieve Wi-Fi for tens of microwatts of power and can do much better than both Bluetooth and ZigBee, you could now imagine using Wi-Fi for everything,” said Joshua Smith, associate professor of computer science and engineering.

The technology has also been named one of the 10 breakthrough technologies of 2016 by the journal MIT Technology Review. A paper describing those results will be presented in March at the 13th USENIX Symposium on Networked Systems Design and Implementation in California. (IANS)

Will Robots Take Your Job? 70 Per cent of Americans Say No

A report issued by the education company Pearson, Oxford University, and the Nesta Foundation found that just one in five workers are in occupations that will shrink by 2030

Washington, October 8, 2017 : Most Americans believe their jobs are safe from the spread of robots and automation, at least during their lifetimes, and only a handful says automation has cost them a job or loss of income.

Still, a survey by the Pew Research Center also found widespread anxiety about the general impact of technological change. Three-quarters of Americans say it is at least “somewhat realistic” that robots and computers will eventually perform most of the jobs currently done by people. Roughly the same proportion worry that such an outcome will have negative consequences, such as worsening inequality.

“The public expects a number of different jobs and occupations to be replaced by technology in the coming decades, but few think their own job is heading in that direction,” Aaron Smith, associate director at the Pew Research Center, said.

The Pew Research Center in Washington, D.C. on July 6, 2005, is the author of a 2017 study looking at the spread of automation and robotics in the workplace.

More than half of respondents expect that fast food workers, insurance claims processors and legal clerks will be mostly replaced by robots and computers during their lifetimes. Nearly two-thirds think that most retailers will be fully automated in 20 years, with little or no human interaction between customers and employers.

Americans’ relative optimism about their own jobs might be the more accurate assessment. Many recent expert analyses are finding less dramatic impacts from automation than studies from several years ago that suggested up to half of jobs could be automated.

Skills will need to be updated

A report issued by the education company Pearson, Oxford University, and the Nesta Foundation found that just one in five workers are in occupations that will shrink by 2030.

Many analysts increasingly focus on the impact of automation on specific tasks, rather than entire jobs. A report in January from the consulting firm McKinsey concluded that less than 5 percent of occupations were likely to be entirely automated. But it also found that in 60 percent of occupations, workers could see roughly one-third of their tasks automated.

That suggests workers will need to continually upgrade their skills as existing jobs evolve with new technologies.

Few have lost jobs to automation

Just 6 percent of the respondents to the Pew survey said that they themselves have either lost a job or seen their hours or incomes cut because of automation. Perhaps not surprisingly, they have a much more negative view of technology’s impact on work. Nearly half of those respondents say that technology has actually made it harder for them to advance in their careers.

Contrary to the stereotype of older workers unable to keep up with new technology, younger workers — aged 18 through 24 — were the most likely to say that the coming of robots and automation had cost them a job or income. Eleven percent of workers in that group said automation had cut their pay or work hours. That’s double the proportion of workers aged 50 through 64 who said the same.

The Pew survey also found widespread skepticism about the benefits of many emerging technologies, with most Americans saying they would not ride in a driverless car. A majority are also not interested in using robots as caregiver for elderly relatives.

Self-driving cars

Thirty percent of respondents said they think self-driving cars would actually cause traffic accidents to increase, and 31 percent said they would stay roughly the same. Just 39 percent said they thought accidents would decline.

More than 80 percent support the idea of requiring self-driving cars to stay in specific lanes.

The survey was conducted in May and had 4,135 respondents, Pew said. (VOA)

India Demands Data on UN Staff Misconduct, Use of Immunity

United Nations, Oct 7: In an attempt to break the wall of silence around the crimes and UN staff misconduct and those on its assignments, India has demanded the secretariat disclose information about such cases and the immunity invoked against prosecutions.

Yedla Umasankar, the legal advisor in India’s UN Mission, touched a raw nerve here by criticising the UN on Friday for not vigorously following up allegations of serious wrongdoing by its employees who enjoy the equivalent of diplomatic immunity, a prized possession of its staff.

“It appears that the UN system itself may be reluctant to waive immunity even for serious misconduct carried out by its personnel while serving on its missions, so that such cases can be prosecuted by the host governments,” he told the General Assembly’s committee on legal affairs.

“Even a few of such instances or allegations of crimes committed by UN personnel is highly damaging for the image and credibility of the United Nations system and its work around the world,” he added.

His statement also touched on the practice of some countries that protect their wrongdoers at the UN.

Umasankar demanded that secretariat disclose how many cases of serious misconduct by UN personnel were registered and the number of cases where the UN refused to waive immunity to allow their prosecution.

He also wanted to know in how many cases the host country wanted the immunity waived so it can prosecute those accused; the number of times the UN asked the host country or the country that sent them to prosecute them; how many times it consulted countries before waiver of the immunity of their personnel and how many of them refused UN’s request to waive their citizens’ immunity.

The information he wanted does not cover the diplomats sent by member countries to represent them at UN bodies and enjoy diplomatic immunity with the nations hosting the UN facilities.

After scores of serious allegations of sexual misconduct by peacekeepers, especially exploitation of children, the UN vowed to uphold a policy of zero tolerance and began publishing data on such cases in peacekeeping operations including how they were dealt with.

Starting with the year 2015, it began identifying the nationalities of those accused.

However, it has not made public a roster detailing all the allegations and proven cases of serious misconduct across the entire UN.

While the focus has been on sexual exploitation and abuse reported on peacekeeping operations, Umasankar said that “at a broader level, the issue of accountability has remained elusive in some cases”.

He attributed it to “the complexities of legal aspects relating to sovereignty and jurisdiction”, the immunity or privileges that may be necessary for UN operations, and the capability or willingness of countries to investigate and prosecute the accused.

He noted that the UN itself cannot make criminal prosecutions.

While Indian laws has provisions for dealing with crimes committed abroad by its citizens, not all countries have them, he said.

Those countries should be encouraged and helped to implement such measures, he added. (IANS)

Indo-Pak Peace Talks Futile Unless Islamabad Sheds Links with Terrorism, says Study

A Study by a U.S. think tank calls India and Pakistan talks futile, until Pakistan changes its approach.

A Top United States of America (U.S.) think tank, Carnegie Endowment for International Peace called the relations between India and Pakistan futile, unless Islamabad changes its approach and sheds its links with Jihadi terrorism.

A report “Are India and Pakistan Peace Talks Worth a Damn”, authored by Ashley J Tellis stated that such a move supported by foreign countries would be counterproductive and misguided.

The report suggests that International community’s call for the India and Pakistan talks don’t recognize that the tension between the two countries is not actually due to the sharp differences between them, but due to the long rooted ideological, territorial and power-political hatred. The report states that these antagonisms are fueled by Pakistani army’s desire to subvert India’s powerful global position.

Tellis writes that Pakistan’s hatred is driven by its aim to be considered and treated equal to India, despite the vast differences in their achievements and capabilities.

New Delhi, however, has kept their stance clear and mentioned that India and Pakistan talks cannot be conducted, until, the latter stops supporting terrorism, and the people conducting destructive activities in India.

The report further suggests that Pakistan sees India as a genuine threat and continuously uses Jihadi terrorism as a source to weaken India. The report extends its support to India’s position and asks other international powers, including the U.S., to extend their support to New Delhi.

Earlier in September, Union External Affairs Minister Sushma Swaraj in the United Nations General Assembly (UNGA) slammed Pakistan for its continuous terror activities. She attacked the country by saying that India has produced engineers, doctors, and scholars; Pakistan has produced terrorists.

Sushma Swaraj further said that when India is being recognised in the world for its IT and achievements in the space, Pakistan is producing Terrorist Organisations like Lashkar-e-Taiba. She said that Pakistan is the world’s greatest exporter of havoc, death and inhumanity.
