Data transfer technology that pretty much discussed in recent years is not Wi-Fi, 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 receivers 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.
