Data transfer technology that pretty much discussed in recent years is not WiFi , but LiFi which utilizes the existence of LED lights . LiFi and founding father , Harald Haas and his team have managed to achieve transfer speeds up to 10Gbps in the last experiment .
In the experiments , Haas uses three LEDs ( green , red and blue ) . And each LED was also maximized to have the speed of 3.5Gbps . The high speeds achieved in this experiment is due to the use of micro – LEDs made ??from the University of Strathclyde . The LED also has the ability to deliver millions of the change of intensity in a matter of seconds .
However the technology is still far LiFi if used for public purposes . This is because the technology LiFi has a small range , because the distance between the receiver with the transmitter must be close . Obviously this is different to WiFi that has a very wide range .
Research on the technology LiFi lately is pretty much done . Previously , researchers from the Fraunhofer Institute Germany ever did in April . Furthermore , the researchers from China also perform similar activities and are able to reach speeds of up to 150Mbps .
Hopefully the information above is useful to you .
