Who actually knew that Wi-Fi will actually be replaced by something that is, in fact, a 100 times faster than it? Technology is always evolving, with the new and better always replacing the old, the slow and the obsolete. And now it seems that Wi-Fi as we know it will also be replaced by something better. Introducing Li-Fi, a new form of wireless communication for computers that is 100 times faster than Wi-Fi.
Li-Fi is a brand new wireless internet technology that rapidly transmits data using flickering LED light fields that work between a frequency of 400 and 800 terahertz. The process is called Visible Light Communication and it works very similar to Morse Code. However, instead of relaying a message, these LED lights continue to flick at such an alarming speeds that they can actually be used to write and transmit things in binary code.
Will Li-Fi Actually Be Utilized By Us In The Future?
It appears so thanks to the efforts of Researchers at Estonian hardware start-up Velmenni. They were successfully able to deploy Li-Fi at a commercial level and their results proved extremely fruitful because they were able to transmit speeds of 1 gigabits per second, or 1Gbps, which is approximately a 100 times faster than current average Wi-Fi speeds that you are experiencing right now.
Chief Executive Officer of Velmenni Deepak Solanki states that:
“We are doing a few pilot projects within different industries where we can utilize the VLC (visible light communication) technology. Currently, we have designed a smart lighting solution for an industrial environment where the data communication is done through the 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.”
Theory vs. Practice
After a period of nine months, researchers at Oxford University have been able to achieve the above-mentioned speeds. However, the speed they achieved in their test labs was 224 gigabits per second, but that is only because they tested the application in a very suitable environment. Obviously, should the tech be deployed at a commercial level, you obviously will not be able to match the same bandwidth. Regardless, the breakthrough is far more as compared to the speeds that are able to be achieved by current Wi-Fi standards.
According to Solanki, he also states that during the future, there will be approximately 14 billion Li-Fi’s deployed worldwide, so not only will we be able to achieve more illumination, but we will also be able to experience far better speeds compared to before. The only question is when can we see the tech deployed on a massive scale?
The technology is still in the testing phase and word hasn’t been going out as to its concrete availability in the mass market. Here’s hoping it comes out sooner rather than later.
