One of the new technologies that SPAL will implement will be Li-Fi technology, a high-speed two-way network and mobile data communication that uses light to transmit information. It is made up of multiple light emitters that form a wireless network, offering a user experience substantially similar to Wi-Fi, except for the use of the light spectrum.

Li-Fi falls into the Optical Wireless Communication (OWC) category. This category includes infrared and ultraviolet communications, as well as visible light. However, the technology is unique in that the same light energy used for lighting can also be used for communication.

Advantages of Wireless Optical Communications:

• Long distance transmission - fast wireless data transfer.
• Transmissions with short distances: from 1 Gbps to 40 Gbps by infrared.
• Real-time communication.
• High data security due to the necessary line of sight.
• No interference and with a latency of 5 milliseconds.
• Range from 5 meters to 30 meters.
• Types of connections: point-to-point and point-to-multipoint.

Li-Fi allows data to be transmitted by modulating the intensity of light, which is then received by a photosensitive detector. The light signal is demodulated electronically. This modulation is done in such a way that it is not perceptible to the human eye.

• Latency 5 milliseconds.
• Data rate up to 1000Mbps.
• Bi-directional, full duplication.
• Point-to-point / multipoint communication.
• AES 128-bit data encryption.
• High-density cells.
• Competitive plug and play and easy to adjust.

• Interfaces: Ethernet, Gigabit-Ethernet, USB3.0 / 3.1 and custom interfaces.
• Range: up to 30m.
• Alignment: up to 5m by 5m range.
• Laser safety: class 1.
• Physical size (LxWxH): up to 50x50x80mm.
• Operating temperature : -40°C to +85 °C.
