Graphene Antenna Could Enable Faster-Than-Fast Wi-Fi

This year, a team of Georgia Tech researchers will build a prototype of their design, which they claim could transmit data at speeds of terabits per second.

What's the Latest Development?

Researchers at Georgia Tech's broadband wireless networking lab have created a schematic of a antenna made of graphene that could allow ultrafast data transfer between devices at short ranges. For example, at a range of one meter, a smartphone or similar wi-fi-enabled device could receive a terabit's worth of data in about one second -- the equivalent of 10 high-definition movies -- and up to 100 terabits per second may be possible at even shorter distances. Later this year, a paper describing the design will appear in the IEEE Journal of Selected Areas in Communication

What's the Big Idea?

Although other studies have been done on graphene's remarkable electronic capabilities, the Georgia Tech research is the first to calculate configurations for a wireless antenna. Strips of the material would be very narrow -- up to 100 nanometers wide and just one micrometer long -- which would allow it to be built on a much smaller scale. One challenge facing the team involves making similarly small and fast electronic components to work with the antenna. For now, they are focusing on completing a prototype within a year.

The big day has come: You are taking your road test to get your driver's license. As you start your mom's car with a stern-faced evaluator in the passenger seat, you know you'll need to be alert but not so excited that you make mistakes. Even if you are simultaneously sleep-deprived and full of nervous energy, you need your brain to moderate your level of arousal so that you do your best.

34 years ago, a KGB defector chillingly predicted modern America

A disturbing interview given by a KGB defector in 1984 describes America of today and outlines four stages of mass brainwashing used by the KGB.

Politics & Current Affairs
  • Bezmenov described this process as "a great brainwashing" which has four basic stages.
  • The first stage is called "demoralization" which takes from 15 to 20 years to achieve.
  • According to the former KGB agent, that is the minimum number of years it takes to re-educate one generation of students that is normally exposed to the ideology of its country.

How pharmaceutical companies game the patent system

When these companies compete, in the current system, the people lose.

Politics & Current Affairs
  • When a company reaches the top of the ladder, they typically kick it away so that others cannot climb up on it. The aim? So that another company can't compete.
  • When this phenomenon happens in the pharmaceutical world, companies quickly apply for broad protection of their patents, which can last up to 20 years, and fence off research areas for others. The result of this? They stay at the top of the ladder, at the cost of everyday people benefitting from increased competition.
  • Since companies have worked out how to legally game the system, Amin argues we need to get rid of this "one size fits all" system, which treats product innovation the same as product invention. Companies should still receive an incentive for coming up with new products, he says, but not 20 years if the product is the result of "tweaking" an existing one.
