A wireless communication system known as Li-Fi (sometimes spelt LiFi) uses light to send information and coordinates between devices. Li-Fi is a light-based communication technology that can send data quickly over the visible, ultraviolet, and infrared spectrums.
Light Fidelity (LiFi), a technology based on Visible Light connection (VLC), replaces cable and wired connection by using light as a medium of communication.2 In essence, LiFi is a version of WiFi that uses light to transport data instead of radio waves.
LiFi has some benefits over WiFi, including more bandwidth, better efficiency, better connectivity, greater security, higher speed, and less expensive lighting fixtures.
LiFi is also immune to electromagnetic interferences that affect radio-based wireless communication technologies, making it more secure than WiFi.
Due to the fact that the technique does not produce electromagnetic interference, it is also useful in places where electromagnetic sensitivity is a concern, such as nuclear power plants, hospitals, and airline cabins.
LiFi is simple to set up and offers a faster data transmission rate for internet-based apps. It employs the optical spectrum, avoiding the congested RF spectrum in the process. Devices using LiFi technology operate efficiently and are thus employed in Internet of Things applications.
By varying the brightness of the light, which is subsequently detected by a photo-sensitive detector, LiFi enables the transmission of data. Demodulating the light signal into electronic form follows. This modulation is carried out in a way that the human eye cannot detect it.
LiFi is powered by visible light, while WiFi is fueled by radio waves. This indicates that it has a photodetector to detect light signals and a signal processing component to turn the information into streamable content.
The Global LiFi Antenna Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A business called pureLifi offers Light Antenna technology for integration into mobile and lighting products.
They can collaborate with manufacturers to incorporate a Gigabit Light AntennaTM into their upcoming connected or lighting product. In order to investigate the utilisation of LiFi components, they provide two types of their evaluation kits (EVK).
Trulifi is a line of LiFi systems by Signify that offers two-way wireless communication with low latency for real-time data streaming, unique physical security, and reliable high-speed connectivity. To transmit data, trulifi systems modulate light waves.
When plugged into a laptop or tablet, a USB access key receives data and transmits it back to a transceiver. Customers of Trulifi receive the best of both worlds by utilising lighting infrastructure: excellent Philips illumination and a dependable, secure, high-speed wireless connection.
