Light Fidelity

Li-Fi is a visible light communication system (VLC), which uses light to send wireless data embedded in its beam. A device with support for Li-Fi converts a beam of light into an electrical signal. Then the signal is converted back to the data.

LED lamps are already performing two functions at once: illuminated the room and create a wireless communication network that will allow you to connect to devices and to the Internet. Communication in the visible range of light This is: - high-speed biologically safe communication for a large number of users.

Such technology can be used in hospitals, in airplanes and in many other cases. This is especially true in conditions of significantly increased levels of electromagnetic radiation in human life.
Li-Fi will also be used to significantly improve internal wireless communications in residential buildings, hospitals, work and recreation areas.

With a detailed implementation of the system, Li-Fi can reach transmission rates that are approximately 100 times higher than modern traditional Wi-Fi, operating on radio waves (i.e., speed can reach more than 1 gigabit per second).

One of the main advantages of LI-Fi technology, in addition to the health of users and others, as well as speed is an increased level of security of transmitted data, associated with the fact that the light does not penetrate through the walls.

Another advantage is to increase the reliability of the network. Li-Fi transmitters can be built into each lamp in the room or in the building, thereby eliminating the narrow place of the Wi-Fi network structure.

These qualities make Li-Fi a particularly attractive alternative in cases where Wi-Fi signals are significantly weakened, or where the use of Wi-Fi is not allowed, as well as where a fast and secure transmission of large amounts of data is required (for example, in hospitals).
