LiFi is a mobile, two-way, high-speed communication technology using light. It consists of several LEDs forming a wireless network. When an electric current is transmitted to these LEDs, a stream of light (photons) is emitted by this device. The LEDs are semiconductors, which means that they can be modulated at high rates. The signal is then received by a sensor that interprets the modulations of the light (the signal) as data. This allows users to be connected wherever a LiFi infrastructure is deployed.  

Yes, LiFi is much more secure than other wireless technologies because it’s possible to define its transmission area, unlike WiFi. By its nature, to access the LiFi network, the user needs to be in the equipped area and to have a dedicated receiver. In addition, our LiFi Controller allows its network to be managed and security to be increased via the encryption and the authentication of its information system.  

Yes, LiFi is a two-way wireless communication technology that enables high-speed data transmission in both uplink and downlink.

We use IR, which is invisible light.

LiFi can work in daylight and even in direct sunlight conditions. The LiFi signal can always be detected. It relies on detecting the modulation of the LEDs, not the natural variations and disturbances of the sun. Our technology is modulated at very high frequencies, and sunlight is a constant light, so it can be filtered by the receiver.  

Yes, masking the receiver could affect its ability to pick up signals. Completely masking the receiver will prevent it from picking up any signals (e.g., a sheet of paper over the receiver). This feature allows users to cut the data connection for an additional security layer.  

 No, LiFi won’t work in your pocket. Placing an entire mobile device, or just the photodiode, in your pocket will prevent any communication. However, once the LiFi  device starts receiving a signal, its high-speed communication will resume immediately.

LiFi systems use LEDs as a transmission medium because they are a semiconductor, which gives them the ability to modulate light at extremely high speeds. These speeds are unattainable with incandescent and fluorescent bulbs. In addition, LEDs are generally considered to be a more efficient light source because they emit in specific wavelengths, so they don’t waste energy.  

LiFi is not intended to replace WiFi, but should be considered as an alternative in certain areas where the use of WiFi (or radio frequency waves) is prohibited, undesirable or inefficient. Our technology can also be used to improve connections in areas where high-speed connectivity is needed.
