LiFi: Security Network
Li-Fi, or Light Fidelity, is a wireless communication technology that uses visible light or the infrared spectrum to transmit data. It is an emerging technology capable of providing secure, high-speed wireless communication.
Some key points of LiFi and its network
High-speed communication: LiFi has the potential to offer significantly higher data transfer rates than traditional Wi-Fi. It is, in fact, up to 1Gb/s and will reach 1 Tbit/s by 2025, according to industry studies. Already today, in the laboratory, it is possible to achieve these speeds that commercially will only be achieved with the advent of 6G, of which LiFi is a precursor, as the sixth generation of connectivity will fully embrace the Thz frequencies of light, from the visible to the unseen.
Limited range and line-of-sight: One limitation of LiFi is its range and line-of-sight requirement. Because light waves do not penetrate through obstacles such as walls, LiFi signals are generally limited to the area where light is present. This, however, may offer inherent security advantages because the signals are less susceptible to interception from the outside. This means that more LiFi light sources or antennas may be needed to cover a larger area.
Interference: LiFi signals are less prone to interference from other devices because the light is less congested than the radio frequency spectrum used by Wi-Fi and other wireless technologies. This can help create a more reliable and secure communication environment.
Network security: LiFi networks can benefit from standard security measures such as encryption (e.g., using protocols such as Transport Layer Security - TLS) to protect data transmission. But because LiFi signals are confined to physical space, the risk of unauthorized access or eavesdropping from outside is extremely low.
Integration with existing infrastructure: LiFi can be integrated with existing lighting infrastructure by taking advantage of the widespread use of LED lights. This allows LiFi to be implemented without the need for additional dedicated infrastructure, making it potentially cost-effective.
Over the past two years, the adoption of LiFi technology by Government and Corporate has increased significantly in parallel with the industrialization and standardization of early application solutions and the relative increasing maturity of the target market. According to recent industry studies, the size of the LiFi market reached $127.66 million in 2021 and is expected to be worth about $15 billion by 2030, with a compound annual growth rate (CAGR) of 51 percent from 2022 to 2030 (Source: www.precedenceresearch.com)
