    Would Wi-Fi be replaced by Li-Fi

    It has been reported that a new technology has been invented by scientists of Mexico known as Li-Fi which is likely to take the place presently occupied by Wi-Fi for data transmission. Extract of the full report, with due acknowledgements, from the Link

    The technology, called Li-Fi or light fidelity, is presented as an alternative to Wi-Fi because it will maximize the original provided speed of the internet to offer safer data transfer and a transfer rate of up to 10 gigabytes per second.The Li-Fi device circulates data via LEDs that emit an intermittent flicker at a speed imperceptible to the human eye. "As Wi-Fi uses cables to spread our connections, wireless transmission Li-Fi uses LED lamps that emit high brightness light," said Arturo Campos Fentanes, CEO of Sisoft in Mexico.Another advantage in comparison to Wi-Fi is that there is no way to hack the signal since the internet is transmitted by light, there is no way to “steal it”.Furthermore, it can be installed in hospitals areas that use radiation apparatus and generally block or distort internet signal, Fentanes said.With this new technology expansion through the market is sought, with lower costs and a service increased by five thousand per cent internet speed.Currently in Mexico the highest transfer rate is 200 megabytes per second. Just to get an idea, with Li-Fi you could quickly download an entire HD movie in just 45 seconds.Also known as visible light communications (VLC), this technology began with an internet speed of two Gigabits per second, but Sisoft along with researchers from the Autonomous Technological Institute of Mexico (ITAM) adapted the system to be multiplied five times.Fentanes explained that the first experiments were conducted with audio, in which a cable is connected via 3.5 mm audio Jack from a smartphone to a protoboard table to transform the auditory signal in optical waves.
