Do you want greater speed of !nternet?

Of course you will notice the spelling of internet in the title. But you will get reason for it why I use the ‘!’ instead of ‘I’ down here.

Moving up one place, the Nordic nation of Sweden is one among the countries offering highest internet speed. The average broadband speed was 14.6Mbps, a quarterly increase of 3.5% and an increase of 34% annually.

Light bulbs are offering new way of delivering data. Yes it would be pretty interesting innovation with the LED bulbs.

Prototype of Li-Fi internet

Hence it was so great to hear, about Li-Fi technology which could the next generation project. A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.
Li-fi can deliver internet access 100 times faster than traditional Wi-Fi, offering speeds of up to 1Gbps (gigabit per second).

You wander for Li-Fi zone? What is Li-Fi?

Li-Fi is a wireless technology similar to Wi-Fi that allows data to be sent at high speeds using visible light communication (VLC). Invented by Professor Harald Haas from the University of Edinburgh, Li-Fi has several advantages over Wi-Fi. Li-Fi allows for greater security on local networks as light cannot pass through walls, which also means there is less interference between devices. It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.
It was tested this week by Estonian start-up Velmenni, in Tallinn.Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 1Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.

It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.
Speaking to the International Business Times, chief executive Deepak Solanki said that the technology could reach consumers “within three to four years”.The term li-fi was first coined by Prof Harald Haas from Edinburgh University, who demonstrated the technology at a Ted (Technology, Entertainment and Design) conference in 2011.

In a TED talk describing the technology, Haas said that current infrastructure was suitable for the integration of Li-Fi.

“All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission,” Haas said. “In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fi s deployed worldwide for a cleaner, greener and even brighter future."

One of the big advantages of Li-Fi is the fact that, unlike Wi-Fi, it does not interfere with other radio signals, so could be utilized on aircraft and in other places where interference is an issue.
While the spectrum for radio waves is in short supply, the visible light spectrum is 10,000 times larger, meaning it is unlikely to run out any time soon.

But the technology also has its drawbacks — most notably the fact that it cannot be deployed outdoors in direct sunlight, because that would interfere with its signal. Neither can the technology travel through walls so initial use is likely to be limited to places where it can be used to supplement Wi-Fi networks, such as in congested urban areas or places where Wi-Fi is not safe, such as hospitals.

*But with the above pro’s of Li-Fi ,it will outweigh the cons.
