LED TECHNOLOGY TO REPLACE WI-FI SERVICE

In the recent times, WI-FI and BLUE TOOTH are the common phenomenon for most of us. These technologies utilizes radio waves for communication. Beware, the radio waves proved harmful for humans: Claimed by a team of scientists that is busy in innovating unique, exceptionally fast technique of wireless communication that does not exercise radio waves; instead, they employ light of LED bulbs.

Despite offering fast speeds, radio waves transmit data slowly, resulting in cracked signal that often blocked or affected by your device, simply as the microwave does in your kitchen. While for the Light-based wireless communication, better introduced as Li-Fi by Herald Haas at a TED talk in 2011, is a process of internet connectivity that works devoid of cables and radio waves by alternating the light from an exclusive LED to broadcast data similar to your existing Wi-Fi gadget. This revolutionary technology is still under extensive study at the University of Edinburgh in the UK. However, it has already established its worth at par performance and proved far safer than predictable radio-based communication system. Wi-Fi works by forcing out radio waves in all surroundings of the vicinity from a wireless router and your Wi-Fi gadget tracks the wireless radio waves, than it hook up to your wireless router and ultimately link your gadget to the Internet. Li-Fi technology also works similarly, instead of radio waves it offers same effect by flickering out light from a LED bulb to hook up your any sort of gadget with internet.

Li-Fi is much safer technology compared to WI-Fi and it works only when your gadget detects the light emitted by its router. That way other people cannot establish link with your Internet connection and share your credit any more. It is also worth mentioning that it cannot be affected by RF-releasing equipment working in the similar room, such as a microwave or radio. Li-Fi working at a high speed of 867 Megabits per second for a typical handheld; however, it can attain a velocity of up to 3.5Gbit/s per color –in other words a common Red-Green-Blue (RGB) LED bulb can produce speeds up to 10.5Gbit/s, more than 10 times faster than the latest Wi-Fi technology, These speeds offer a lot of potential for wireless connectivity.

Light is already used in transfers of long distance information through Fiber Optic Cables; it is the key high-speed internet data-transmitting source round the globe. Li-Fi functioning same as fiber optics for broadcasting the info, except for one reason that it lets the light deflect in all directions so all gadgets in the same room or vicinity can hook up. This innovative technology is hanging around for its extensive exploitation in our routine life, within few years time it will be part of our homes, the great potential is in the offing, laboratory controlled tests demonstrates a tremendous promise of Li-Fi technology. Hopefully with its access to the public in near future WI-Fi may soon become a distant memory.
