Free Wi-Fi has become so widespread phenomenon that stickers on the windows of the cafe, announcing free hotspots in major cities have become something like atavism. However, the location of the new hotspot can impress even the most advanced technocrats: The world's first scientists were able to send a wireless internet signal through 384,400 kilometers separating Earth and the Moon.
Successful demonstration, conducted by researchers from NASA and MIT, means that the future conqueror of the moon can Chekina in the Sea of Tranquility and send lunar self at a higher rate than the fastest network here on Earth.
The team will present the obtained results of the experiment, June 9 at the Conference on Laser Technologies CLEO in California.
To create a link with the Moon, scientists used four separate telescopes in New Mexico, which transmits a signal to a receiver mounted on an orbiting satellite, the Moon. Each of these telescopes is about 15 centimeters in diameter and works in tandem with the laser transmitter, which transmits information in the form of coded pulses of infrared light.
Since the atmosphere of our planet distorts the signal as it moves toward the moon, all four telescopes transmit light through the different columns of air, each with its own degree of distortion. This approach increases the chance that at least one beam will reach the satellite and establish communication with the moon.
And I must say, this relationship is not bad. Scientists were able to transmit data from the Earth to the moon at a speed of 19.44 megabits per second and the "download" data from the Moon to the stunning 622 megabits per second. At the request of the British technical analysts, it is more than 4,000 times faster than today's broadcasts.
So, in light of recent events, we still have only one question that what will be the password?
