Researchers at Harvard University in the United States have developed a laser radio frequency transmission method that can facilitate the development of high-speed Wi-Fi. According to a study published by the National Academy of Sciences, this method is based on the use of lasers for the elimination of Tera-herca waves capable of transmitting data with high frequency, that is, radio frequency transmission with a semiconductor wireless laser.

Data transfer is expected to be 100 times higher than current standards. This technology is still in the testing phase and there is no start-up for everyday use, but according to researchers, it is already a great achievement to end the problems of Wi-Fi networks.

According to the survey, data transfer can be hundreds of times higher than the current wave. The reason is the frequency of wave emissions. With these lasers, several waves are emitted at the same time and are captured by a special antenna developed by the University. This antenna could decode the lasers and extract the internal files that were later transferred to the computer.
Currently, the most advanced technology supporting high-speed internet is fiber optics. However, Wi-Fi transmission is still delayed because signals may be lost, for example, between the router and the notebook. In addition, electromagnetic waves are often disturbed.
