New Buzzword “Li-Fi” 100 Times Faster Than “Wi-Fi”
from Times Gazette

A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.

Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).

“We’re now carrying out a few pilot jobs within different companies where we can employ the VLC (visible light interaction) technology”, Deepak Solanki, CEO of Estonian tech firm, Velmenni, advised IBTimes UK.

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. So Li-Fi is a blessing for all the internet savvy people and will also be a much cheaper option.

The term was first introduced by Professor Harald Haas of Edinburgh University and is now being tested in Europe. The laboratory tests confirmed a speed of 224GBps with Li-Fi. The data was received by a binary code by flashing LED lights on and off â€" creating a Morse code. Today, professionals took Li-Fi out of the research for that first time, screening it in offices and professional situations. Li-Fi was made available in an office environment where workers we able to access the Internet in a commercial setting.

Just like Wi-Fi, Li-Fi too uses similar 802.11 protocols, but it uses visible light communication instead of the radio frequency waves.

You will find more benefits than pace. Specialists, however, do not believe that this may phaseout Wifi. Radio signals need permissions and were limited, and thus the LED light technology could be explored. For instance, it can not be deployed easily outdoors under direct sunlight as that would interfere with the signal. Li-Fi is a subset of optical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or replacement in contexts of data broadcasting.
