Is “Li-Fi” the Next “Wi-Fi”?

It means Li-Fi can deliver internet access 100 times faster than Wi-Fi by offering a speed of up to 1GBps (Gigabite per second). Also, Wi-Fi connectivity causes security vulnerability for data and storage and even though Li-Fi is a challenge to achieve at present, it seems to be positive news. He goes on to say, “Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light”.

The term was first introduced by Professor Harald Haas of Edinburgh University and is now being tested in Europe. This is a process known as Visible Light Communication and is most easily understood as something a bit like visual Morse code.

While Li-Fi does come with the advantage of not interfering with radio signals, a lot of the benefits are overpowered by the simple fact that visible light can not travel through walls, an essential factor which gives old-school Wi-Fi a huge advantage.

With a 100 times speedier internet delivery, Li-Fi (Life fidelity) works at a 1GB speed per second by using an LED bulb, internet and photodetector as a source. Remember this expression – “Li-Fi”; it truly is likely to be used very often soon enough.

“When a constant current is applied to an LED [light-emitting-diode] lightbulb, a constant stream of photons are emitted from the bulb which is observed as visible light”.

Li-Fi was tested earlier in the week by an Estonian startup called Velmenni, and the company was able to crank out incredible speeds of when it tested the technology in Tallinn. It uses visible light communication or infrared and near ultraviolet spectrum, which carries much more information than the traditional wireless internet. Actually, that’s how the signals are transmitted, through a light. Rather, the two systems may be applied together to accomplish secure and more effective systems. “Inside The future we’ll not just have 14 billion lights, we might have 14 billion Li Fis deployed worldwide for an even better, greener, and cleaner future”, it involves Asia, also if this technology does pot out, it’d imply everyone who has an LED bulb could have usage of the internet. One possible situation domestically is the employment of a Wi-Fi network for general use and a couple of Li-Fi hotspots for high-speed uses.
