Among them, the Indian Ministry of Information Communications (meity) is now working with the Indian Institute of Technology (ITT) and Philips India to study the LiFi technology, hoping to be complementary to the optical network, which can be used in areas without fiber-optic networks but with power, and in hospitals or diving equipment. According to their research, the speed of LiFi can reach 10GB per second within a 1 km range.
Neena Pahuja, managing director of the Network Education Research Division of the Ministry of Information and Communication (ernet), said LiFi could be used in smart cities, which would become the main infrastructure of India, and that they would be able to connect to the Internet of Things (IoT) and be connected to LED bulbs.
Ernet has been experimenting with ITT and Philips in laboratories in the laboratory, and the technology is about to enter the outdoor testing phase, Pahuja that the new technology will be tested outdoors at the Indian Science Institute of Technology (IISC) in Bangalore, India.
LiFi, a professor at the University of Edinburgh, Harold Haas, was first introduced in 2010, and according to the study, LiFi can simultaneously complete both high-speed Internet and lighting. But although he has the advantage of high-speed transmission and high security, the signal will be interrupted as long as the light is obscured or blocked.
Pahuja said the LiFi could not penetrate the walls and needed an unimpeded space to transmit the signals, which were widely used in the market and at a distance. And we think that the net LED light (mesh of LED lights) is a solution. and India Jawaharlal. Researchers at the Centre for Scientific research, such as Niehrugau, JNCASR, a laboratory professor Ks Narayan, said that while the walls could reflect light, the signals would weaken and we could use more light bulbs to maintain the signal source.
LiFi new field of information security and research
JNCASR is currently working to improve the safety of LiFi, hoping to enhance the security of the network in the future smart city. The researchers applied phosphor (fluorescent) and phosphorescent paint on the walls (phosphorescent piant), which absorb light and increase noise, limiting the use of LiFi.
But after absorbing the light, the phosphorescent paint will continue to glow after the light is turned off, and this has opened up new research areas, Narayan that if the light emitted by the phosphorescent paint can be used as a signal source, it means that phosphorescence can continue to signal for hours even if the lights are turned off.
Oledcomm, a French company, pushed LiFi products at CES in 2014 to transmit information at a high speed with a pulsating flash that could not be perceived by the naked eye. And the U.S. company Vlncomm also this year to develop the first LI-FI LED lighting panel, equipped with white light led, to provide 108Mbps download speed, but also with the 253Mbps upload rate of "lumistick", the domain range of 516 square feet.
