Oledcomm, one of the most technologically advanced companies in the world for LiFi, installed LiFi-enabled LED lights at the emergency hospital center in Perpignan in 2014. The hospital became the first in the world to have LiFi. When a patient is admitted to the hospital, Dr. Jean-Marie Bonnec, the director of the emergency department in Perpignan, uses a computer connected to the Internet if he wants to consult his medical file. However, wireless connectivity is not achieved through a Wi-Fi network, but through a LiFi system.
Dr Jean-Marie Bonnec said: "To move between rooms, we connect via LiFi, which is a wireless connection that uses light waves, with the luminous receiving signal terminal hanging on a luminous signal light in the corridor. The use of LiFi avoids radiation from patients and medical staff receiving radio waves.
LiFi technology uses LED light modulation to transmit information to a dedicated receiver that decodes the data on a computer, tablet, or smartphone. The transmitter/receiver intercepts flickering emitted by the bulb and is imperceptible to the naked eye. Suat Topsu, founder of a startup that Oledcomm wants to meet the challenges of "photo-fidelity" technology, puts it this way: "We use a traditional box to get the internet through the power network. We send the entire internet connection to each light bulb via the power network. The luminaires began to flash more than ten million times per second, transmitting video over LiFi, for example, to a laptop. Of course, 10 million times, the human eye can't see these flashes, but computers, smartphones, tablets can. "
The IT manager of the Perpignan Hospital was impressed by the concept of LiFi technology and decided to gradually replace Wi-Fi with LiFi. "Where we installed LiFi, we measured electromagnetic waves of 269 millivolts per meter, which is far below the World Health Organization's recommendation of 600 millivolts per meter. We still have Wi-Fi, and we measure 3 volts per meter, which is ten times higher than what we do in areas with LiFi. Vincent Templier, head of the IT department, said: "Our goal is to suppress radio wave technology that allows us to improve the care and well-being of our users, while also improving the working environment of our employees.
