Merits of Li-fi TechnologyWi-fi is great for general

wireless coverage while Li-fi is ideal for high density coverage in a confined region.

 It is believed that the technology can yield a speed more than 10 Gbps, allowing a HD film to be downloaded within 30 seconds.

De - Merits of Li-fi Technology

The light waves cannot penetrate walls.

it was detectable up to a distance of 10

meter.

It is similar to the Wi-fi except that it uses

Light waves instead of Radio waves.
