The Li-Fi has just been tested in the real world, and it's 100 times faster than Wi-Fi Sorry, Wi-Fi.


Expect to hear a whole lot more about Li-Fi - a wireless technology that transmits high-speed data using visible light communication (VLC) - in the coming months. With scientists achieving speeds of 224 gigabits per second in the lab using Li-Fi earlier this year, the potential for this technology to change everything about the way we use the Internet is huge. And now, scientists have taken Li-Fi out of the lab for the first time, trialling it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second - that's 100 times faster than current average Wi-Fi speeds.

"We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology," Deepak Solanki, CEO of Estonian tech company, Velmenni, told IBTimes UK. "Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the Internet in their office space.” Li-Fi was invented by Harald Haas from the University of Edinburgh, Scotland back in 2011, when he demonstrated for the first time that by flickering the light from a single LED, he could transmit far more data than a cellular tower. Think back to that lab-based record of 224 gigabits per second - that's 18 movies of 1.5 GB each being downloaded every single second. The technology uses Visible Light Communication (VLC), a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code - just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit things in binary code. And while you might be worried about how all that flickering in an office environment would drive you crazy, don’t worry - we’re talking LEDs that can be switched on and off at speeds imperceptible to the naked eye.

FIFA RELEASES THE BALLOND'OR LIST


Now the 23-man list has just been reduced to three names and includes two Barcelona players, with the winner to be revealed at a ceremony in Zurich on January 11, 2016
Lionel Messi Cristiano Ronaldo and Neymar will contest the 2015 Ballon d'Or competition after the shortlist was whittled down from 23 names to just three. Messi which is the favourite to land the accolade, having led Barcelona to a famous treble last season, while Ronaldo is looking to defend his crown and draw level with the Argentine for overall wins. Were he to pick up the Ballon d'Or at the ceremony in Zurich on January 11, 2016, it would be Messi's fifth World Player of the Year title, more than any other player.

Doomsday ideology of ISIS The terror group’s apocalyptic vision is a powerful recruiting pitch

In a boastful press release after the Paris attacks that left 130 dead earlier in the month, ISIS celebrated its “victory” over the city it called the “lead carrier of the cross.” “Allah granted victory upon their hands and cast terror into the hearts of the crusaders in their very own homeland,” the group wrote. The medieval language is a glimpse into the terror group’s little-discussed apocalyptic ideology, one that draws on prophecies written after Muhammad’s death that were used to motivate Muslims to battle by caliphs who lived more than a thousand years ago. While al-Qaida occasionally hinted at these doomsday writings foretelling a grand battle with infidels at the end of the world, ISIS has made them the bedrock of its brand.

These prophecies are so entwined with ISIS’ identity that the group has pasted a line from one of them — “a Caliphate in
Accordance with the Prophetic Method” — on the coins it has minted, on the badges soldiers wear and even on a billboard marking the beginning of ISIS territory. In that prophecy, Muhammad said that after a “tyrannical monarchy,” an Islamic caliphate would return. The formation of the caliphate would lead to a grand battle with the West that would bring along the end of the world.
The prophecies ISIS relies on were written dozens and sometimes hundreds of years after Muhammad’s death and are not included in the Quran, as Brookings scholar Will McCants explains in his book “The ISIS Apocalypse.” But the prophecies are widespread and believed by many —one poll in 2012 suggested half of Arabs believed the end of the world was nigh. In ISIS’ interpretation, the figure of the Mahdi, or “the rightly guided one” will appear to lead final battles against the Western infidels, called Rome, in northern Syria before the end of days. After the day of judgment, only those who supported the Mahdi will be saved. The Mahdi will appear after the establishment of an Islamic caliphate. (Medieval caliphs, attempting to gin up support for their own battles against the Christian crusaders, claimed to be the Mahdi in the past.) In some of the prophecies, Jesus descends from the heavens to assist the Mahdi in his battle against the infidels, who are led by an Antichrist figure. ISIS leadership has made key military decisions based upon these prophecies. It fought in the summer of 2014 to take over the small and militarily unimportant village of Dabiq close to Turkey because it is name-checked in one of the prophecies as a place where the final great battles will occur. The infidels are supposed to gather under “80 flags” in this village, before their defeat. (Dabiq is also the name of ISIS’ monthly magazine.) ISIS’ also claimed that the apocalypse is nigh is a powerful recruitment tool, not unlike an “Act now! 24 hours only!” sales pitch. “The belief that the end of the world is coming and you’re going to be fighting on the side of the good guys when the world ends is a powerful motivator,” McCants told Yahoo News. “Young people going to join [ISIS] believe they are participating in a apocalyptic prophecy.” “The really interesting thing here from the psychological perspective is the sense of urgency,” said John Horgan, a psychologist and terrorism expert at Georgia State University. “They’re sending the message that the forces of evil are about to reach their goals so you need to act now rather than later.
