Li-Fi, the new wireless technology that uses modulated LED light to transmit data, has some key advantages over Wi-Fi. Here are 10 ways Li-Fi outperforms traditional Wi-Fi
Li-Fi provides incredibly fast data transmission, up to 224 Gbps in lab tests. Wi-Fi peaks at around 3 Gbps.
Li-Fi signals are confined to illuminated spaces, making it much harder to intercept data. Wi-Fi data can be accessed beyond walls.
The short range of Li-Fi allows access points to be installed a meter apart with no interference. Wi-Fi zones overlap.
No Spectrum Crunch
Li-Fi uses visible light so doesn't compete in the crowded radio spectrum bandwidth. More networks can co-exist.
Li-Fi network capacity can be adjusted on demand simply by turning lights on or off in different areas. Wi-Fi requires manual router tweaks.
Li-Fi uses harmless light so it can be safely used in places like hospitals and aircraft. Wi-Fi emits radio waves.
Lower Power Usage
The high efficiency LEDs used in Li-Fi draw less power than Wi-Fi. It's greener.
No Signal Drops
The closed cabins of planes make reliable Wi-Fi hard to deliver but are ideal spaces for contained Li-Fi networks.
Li-Fi can provide centimeter-level localization not possible with Wi-Fi's longer range. This enables precise positioning services.
The immense spectrum of visible light provides nearly limitless bandwidth for Li-Fi, unlike radio frequencies used by Wi-Fi.
While Wi-Fi currently enjoys wider adoption, Li-Fi offers faster speeds, tighter security, safer operation and other advantages that make it a promising technology for the future of wireless communication.
