Li-Fi New Technology Which Is 100 Times Faster Than Wi-Fi
Li-Fi is finally moving out of the research labs to the real world
environments. This super-fast alternative to Wi-Fi has been tested in a
commercial context by Velmenni, an Estonian startup.
This
technology uses visible light to transmit high-speed data.
Earlier this
year, Li-Fi was tested in the labs and it achieved speeds of 224
gigabits per second. Now, in Estonia, in the first time field testing,
it has been reported that Li-Fi achieved a data transmission rate of 1GB
per second i.e., 100 times the current average Wi-Fi speeds.
Li-Fi
dates back to 2011, when it was invented by Harald Haas of the
University of Edinburg. Using a single LED, he demonstrated that it
could transmit more data than a cellular tower. Now, testing it in the
real-life scenarios, Velmenni has designed a smart lighting solution for
an industrial environment.Deepak Solanki, CEO of Velmenni told IBTimes UK: “We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology.”
Li-Fi allows greater security to the data on local networks as light can not pass through walls and ensures lesser interference due to other devices. Professor Haas, the Li-Fi inventor, has said in the past, that every future LED bulb could be used to beam ultra-fast internet via Li-Fi.
It should be noted that Li-Fi might not completely replace the existing Wi-Fi technology as ripping off all the existing Wi-Fi infrastructure doesn’t seem very economical. However, it can be used to complement Wi-Fi as a parallel network.
