Description
Yes, it's time to shift from Wi-Fi to Li-Fi — an alternative technology that is 100 times faster than the average speeds of Wi-Fi.
Scientists have just field-tested the new wireless technology called Li-Fi for the first time and achieved marvelous wireless speeds that are 100 times faster than current WiFi speeds.
What is Li-Fi Technology?
Li-Fi is a new wireless technology that transmits high-speed data using light (i.e. Visible Light Communication or VLC) rather than radio bands.
In short, Li-Fi is a Super-Fast alternative to Wi-Fi.
Earlier this year, scientists achieved mind-blowing speeds of 224 gigabits per second (Gbps) in the lab using Li-Fi. It's believed that this technology has the potential to change everything about the way we use the Internet today.
And Yes, it will.
Test Results: Li-Fi is 100 times Faster than Wi-Fi
An Estonian startup company called Velmenni took the technology out of the laboratories and into the real-world offices, and industrial environments in Tallinn for the first time and, believe me, it's really, really fast.
The company was able to transmit data at 1GB per second, which is almost 100 times faster than the Wi-Fi speeds.
> "We are doing a few pilot projects in different industries where we can utilize the VLC technology," Velmenni's CEO Deepak Solanki told IBTimes UK.
"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through the light. We're also doing a pilot project with a private client where we're setting up a Li-Fi network to access the Internet in [our] office space."
Unlike Wi-Fi network signals, Li-Fi is based on light and can't penetrate through walls, which makes it more secure from external sniffing. Meanwhile, it also means there is less interference from other devices.
Who Invented Li-Fi?
The Li-Fi technology was originated in 2011 by German physicist Harald Haas, who outlined the idea of using light bulbs as wireless routers during a TED Talk. He demonstrated that with a flickering light from an LED, one could transmit more data than a cellular tower.
