LiFi

LiFi

Nowadays Wireless technology is not odd to us, we use Wi-Fi technology, our mobile phones and other things that are wireless. Wireless technology has become the utility of our daily life like electricity and water. Up to the date we have been using radio waves to transmit our data. These waves are transmitted through radio cellular masses or BTS towers.  There are around 1.5 million cellular masses of these types which consume a huge amount of energy but their efficiency is only by 5%. Isn’t it the wastage of energy?

Here we have another issue as well.  We are often asked to switch off our mobile phones in planes, hospitals and fuel pumps due to security issues with these radio waves. Also, Wi-Fi routers are not installed everywhere so that people could get benefit out of it.  Then what to do?

We have television remotes at our homes that have an LED fixed in the front. When we press any button on it, it generates a signal through LED and communicates with the television.

Keeping this in view, Harald Hass proposed his theory which is termed as “Visible Light Communication system” using LED’s. This technology is actually based on the light and light is everywhere so we can use this technology even in planes, hospitals and fuel stations too! It don’t have any capacity issues because light waves can carry 10,000 times more information than radio waves. The infrastructure for this system has already been designed i.e. 4 billion light bulbs which is already present.  What we need to do is just replace these incandescent light bulbs, we have at our homes and work places, with LED’s light bulb and a microchip . Since LED is semi-conductor device so its intensity can also be controlled.

Some Chinese engineers have already invented such light bulbs in Oct.2013. If these bulbs would replace incandescent light bulbs then in future we won’t only having 4 billion light bulbs but Li-Fi routers also. And then probably in future we would have free internet accessibility everywhere!

This is Li-Fi which is termed as 5G technology.

    how about the cost of the LED bulb with a microchip.? :/

    @Owais I said that they have invented such LED bulbs, but as you said cost is the issue. Now they are working on this to reduce cost, so everyone can afford. 🙂

    you said that Chinese already invented such bulb, they also mention the cost.. 🙂

    healthy information…!! good work #HAMZA

    Good blog written by Mr.Humza but it is more better if you compare the cost of this technology with WI-FI.
