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:

Protect your network with Li-Fi!

Safe Browsing: One of the most important and discussed issues of recent years. A trend that over time will be increasingly significant. 

Li-Fi and security. The most well-known hacker attacks include ransomware and password attacks. In the first case it is a malware stealing personal data and asking for a ransom to get the data back. This type of attack is the one that hit the Lazio Region in August 2021.

The second type of hacking mentioned, however, aims to subtract the credentials of access to our digital life. The two most frequently used password cracking techniques are: social engineering, using email or fishing messages convinces the user to communicate their password, and credential stuffing, you hack the database of a service containing a large number of user passwords and try them on other sites. In the latter case, famous is the episode that hit LinkedIn in 2012 when about 164 million credentials were stolen and were put on sale in 2016.



It’s interesting to notice how even Wi-Fi, the most widely used technology today, can be so vulnerable. How is that possible? Let’s look at the technique called DNS (Domain Name Server) hijacking, through which hackers enter a network without the owners realizing it. It is a technique that allows users to be redirected to websites specifically designed to infect computers or induce victims to reveal sensitive data.

In particular, the router hijack variant can put our Wi-Fi network at risk: very few users, in fact, have the foresight to change the credentials of their routers and the standard ones, usually, are predefined and identical for all devices sold. It’s easy for hackers to retrieve credentials, access your router, and redirect our searches to unsafe websites.


Why is Li-Fi a safe technology?

LiFi is, to date, one of the safest technologies for data transmission because instead of using radio frequencies as a connecting vehicle, it uses infrared and visible light spectrum. All waves that are not able to overcome physical barriers: the network becomes invisible for those outside the light beam of LED lamps.



By installing LiFi solutions, a hacker to connect to the network should be physically present within the room. One can also create localized network offices that allow access only to some departments and not to others. All that said, it makes clear that Li-Fi can be really a great ally to surf the net safely.

Digital Threats: LiFi’s Answer to Hacker Attacks

Connect one or more computers to the internet extremely fast without the risk of external hacker attacks.

How important is cybersecurity to the digital transformation process?

According to a study conducted by Cybersecurity Ventures, cybercrime will leave a significant impact within 2025:  an amount of about 10 trillion dollars will go to fight cybercrime, an annual increase of 15%. This data is concerning for many companies, that find themselves having to implement several costly security measures to counter the increasing external hacker attacks.

To meet companies’ needs, LiFi S would represent an ideal solution to significantly reduce cybercrime. It is a wireless system that provides a fast, safe, and sustainable connection, that can reach a speed of 1 Gbps without emitting radio waves. Thus, this system is free from electromagnetic pollution, external hacker attacks, and interference problems.


How Does it Work?

The main innovative characteristic of this technology lies in data transmission through light wave modulation, thus offering benefits such as high-speed, large bandwidth, security, and sustainability. A LiFi S installation can transmit and receive data at a very fast rate, without issues of band saturation, signal interception, or electromagnetic pollution because of radio waves.

Taking all these benefits into account, it can be stated that LiFi S is the ideal solution to the corporate world’s needs, where cybersecurity must be elevated and the number of devices having access to the network must be well defined. This technology would offer a connection whose speed and quality are unprecedented. Converting light sources into hotspots that collect and transmit data is, therefore, the best option to guarantee security and privacy in work activities.
