Is Li-Fi the Future of Wireless Internet?

Li-FiYesterday we told you how Christmas lights could interfere with your Wi-Fi connection. Today, we’ll tell you about how a light bulb could be your Wi-Fi connection. Isn’t technology grand?

Li-Fi, a new Internet technology based on light has been in the works for a few years, but has now reached a new pinnacle in its development. A New Delhi start-up called Velmenni has recently used a Li-Fi enabled light bulb to transmit data at 1 GB per second, which is 100 times faster than speeds enabled by current Wi-Fi.

Velmenni used Jugnu smart LED bulbs to conduct its test, which saw the company transfer data through visible light. It posted a video of the test, in which the CEO Deepak Solanki holds a wireless device to the lightbulb and the device streams videos without any lag. However, the minute Solanki puts a hand in front of the lightbulb, the connection is broken.

Due to the limited span of Li-Fi, it has been slow to develop. It cannot travel through walls and it requires lights on at all times, which could get expensive. These limitations may be good for security reasons. It cannot be hacked by anyone who is not directly in the room. At the same time, it could be used to connect every device in an office.

In its report on the technology, the International Business Times said that the technology can theoretically reach speeds of up to 224 Gbps. Imagine downloading an HD movie in mere seconds. Incorporating Li-Fi into our daily lives could significantly improve Internet use but first developers need to find a way to integrate it with technology we already have.
