The Future Generation Internet Technology is LiFi(Light Fidelity).
Advantage LiFi over WiFi are:
Li- Fi uses light rather than radio frequency signals so are intolerant to disturbances. VLC could be used safely in aircraft without affecting airlines signals. Integrated into medical devices and in hospitals as this technology doesn’t deal with radio waves, so it can easily be used in all such places where Bluetooth, infrared, Wi-Fi and internet are broadly in use. Under water in sea Wi-Fi does not work at all but light can be used and hence undersea explorations are good to go now with much ease. There are billions of bulbs worldwide which just need to be replaced with LED’s to transmit data. Security is a side benefit of using light for data transfer as it does not pe*****te through walls. On highways for traffic control applications like where Cars can have LED based headlights, LED based backlights, and they can communicate with each other and prevent accidents. Using this Technology worldwide every street lamp would be a free data access point. The issues of the shortage of radio frequency bandwidth may be sorted out by Li-Fi.
