LiFi simply explained: This is how the Internet works from the lamp
The new LiFi technology enables access to the Internet through a special lamp. The technology with light signals is also up to 100 times faster than conventional WLAN. You can find out how LiFi works below.
LiFi technology - how it works
The abbreviation LiFi stands for Light Fidelity and means rendering through light.
- This is also how LiFi works, because the data is passed on via light signals.
- The specially developed LEDs in the LiFi lamp are constantly switched on and off very quickly in order to generate a light signal.
- This flickering is not visible to the human eye. So it seems to you as if the light was permanently on.
- The light signals emitted are then collected by a sensor in a wide variety of technical devices and converted there into electrical impulses.
LiFi in everyday life - these are the advantages and disadvantages
The technology already works well in the laboratory, but it has to struggle with any problems in everyday life
- A disadvantage is that the light signals can be blocked by other objects standing between the light source and the receiver.
- It would also be very tedious and difficult to create an infrastructure only for this technology, since WLAN can be used in everyday life without any problems and all previous technology is based on WLAN.
- A big advantage of LiFi over WLAN is its speed: 100 times faster data transfer is expected. A 16-fold increase in speeds already works under laboratory conditions and other prototypes already have the speed of a gigabit network that runs over cables.
- That is why LiFi should generally make data transfers more efficient and, above all, more secure.
- A previous idea to integrate LiFi into everyday life is to support conventional WiFi with LiFi.
