Today, in the 21st century, wireless networks become an important part of our daily life that make our communication and connectivity easy between multiple devices. WiFi and LiFi are two main types of wireless network that have completely changed the way we transmit and receive data.

LiFi: Wireless Communication: The Future.
LiFi, commonly referred to as Light Fidelity, is a new wireless technology, which utilizes visible light to transmit data. On the contrary, LiFi, unlike WiFi that utilizes wave radio signals for transmission, uses modulation of light intensities of LEDs to create a fast wireless communication channel. The novelty of this method has many advantages over the wireless systems in the traditional form.
A LiFi advantage is its capability to send data at very high speeds. LiFi could reach data transfer speeds of up to 100 times faster than WiFi so it is suitable for applications where high bandwidth is required, for example streaming high-definition videos or large file transfer. Alternatively, light cannot penetrate opaque objects, and consequently, the signal is limited to a specific place, which means that it is safe from eavesdropping or unauthorized access.

WiFi: The Everywhere Wireless Coverage
Wi-Fi, which stands for Wireless Fidelity, is now a common word and is regarded as a pillar of our everyday life. It uses radio waves to maintain wireless communication between devices within the specified range. WiFi has transformed the internet connection since it enables us to connect to the internet in no time and access the online resources, file sharing, and remote collaboration. One of the main advantages of WiFi is its widespread adoption and availability. WiFi is found in homes, offices, public spaces, and even on airplanes, which allows the users to connect to the internet on a convenient and flexible way.ย

Complementary Technologies
LiFi and WiFi are not mutually exclusive. They can however, be used together to improve the overall wireless experience. For instance, in areas where RFI is an issue, such as hospitals or industrial sites, LiFi can be employed to ensure interference-free and secure communication. Wi-Fi, however, can be used for wider coverage and less complicated applications.

Applications of Wireless Networks
Both LiFi vs WiFi can be used in different industries and sectors with a wide scope. In healthcare, the wireless networks provide for the transmission of patient data, remote monitoring, and telemedicine services. In education, they facilitate e-learning, virtual classrooms and access to digital materials. The corporate environment utilizes wireless networks to support remote collaboration, video conferencing, and secure file sharing.
Moreover, wireless networks have changed the way we interact with smart devices and the Internet of Things (IoT). From the management of home automation systems to the tracking of fitness data on wearable devices, wireless connectivity is a vital part of our daily life.
Conclusion
The need for higher-speed, more secure, and faster networks will increase with the development of technology. WiFi has reigned supreme in the wireless domain for years, but LiFi is coming up as a potential successor, offering never before seen data transfer speeds and improved data security. With the rapid evolution and convergence of these two technologies, we can only imagine to see more pioneering applications and innovations that will define the future of wireless communication.
