The world is increasingly dependent on the internet. From government affairs and work to traveling and grocery shopping, tasks and daily activities are made easier with wireless communication technology. Wi-Fi, or wireless fidelity, has been supporting this connection over the years. However, as dependencies become more abundant and digital transformation storms in, increasing in importance and making more activities possible online, Wi-Fi performance has become questionable in keeping up with these transformations. Significantly, this has brought about an increase in mentions of a Wi-Fi-like technology called Li-Fi or light fidelity. What are the benefits of Li-Fi?
Even though Li-Fi has existed since 2011, its implementation can only be observed in certain fields. This is because Li-Fi is considered a new technology, resulting in limited compatibility with many devices. Additionally, its coverage is limited to a range of up to 10 meters, making it particularly effective in confined spaces. While this means that the implementation of Li-Fi still has a long way to go, studies and researchers indicate that its capabilities are superior to Wi-Fi. Therefore, Li-Fi has many benefits. The benefits of Li-Fi include:
Speed – Visible light spectrum is nearly 10,000 times larger than the spectrum occupied by radio waves. This make Li-Fi to be able to transfer data faster (at higher speed) than that of Wi-Fi.
Cost effective – Li-Fi involves the use of visible light as a medium to transfer data, which can be achieved with standard LED technology. LEDs are already installed in many devices, appliances, and spaces, which helps reduce the cost of installing various devices such as routers, modems, signal repeaters, wave amplifiers, and antennas, as well as cabling.
Security – Data security has always been a top concern in data transmission. Since Li-Fi utilizes visible light to transfer data, its capabilities revolve around light characteristics, making it a more secure technology for data transfer. Light, which can be blocked by opaque objects, enables the connection to be better safeguarded, as it cannot be intercepted by individuals outside the network.
Availability – All light sources can be integrated into Li-Fi, allowing multiple appliances and devices to be set up as transmitters. This expands the availability of Li-Fi, making it possible to define more spaces as hotspots.
In conclusion, the emergence of Li-Fi offers a promising alternative as limitations of traditional Wi-Fi technology become apparent. Despite its relatively recent introduction, Li-Fi has shown remarkable potential in terms of speed, cost-effectiveness, security, and availability.
