WiFi or LiFi network Which one is more secure? Why?

LiFi technology is more secure than WiFi and also allows connections thousands of times faster than our current ones.

LiFi technology has gained popularity and weight in recent months as an alternative to WiFi. Instead of sending data through a radio signal, that is transmitted through the air, the LiFi sends its data through the light of a LED bulb. Lab tests have managed to reproduce connections up to 224 Gbps, which is thousands of times faster than WiFi.

Why is WIFI unlimited whereas Cellular data is limited ?

Why Not Distribute Wi-Fi Over the Distributed Antenna System (DAS)?

LiFi is not only a faster transmitter of data than WiFi, it also has other interesting advantages as well.
For example, this technology does not interfere with radio signals, or airlines, allowing it the opportunity to become the ultimate gateway to taking the Internet to airplanes. However, a simple wall that does not let light pass, becomes an insurmountable obstacle for LiFi. This limitation could serve to create a safer system, although it is not quite clear what the minimum distance of its signal reception is as of yet.

It must be said that currently computers, cell phones, tablets, smart TVs and other devices that can connect to the Internet lack the compatibility to do it via Li-Fi. So far though, this has been made possible thanks to a USB device that connects to the device.
