Free Wi-Fi today - it's so common that stickers, notifies and located everywhere, have already become in big cities is quite usual for people accompanying any public place.
But the location of a new hotspot sure to impress even the most advanced technocrats: unbelievable, but scientists have managed to send a wireless signal to the Internet on the moon, on the distance from the Earth to 384,400 kilometers.
Experts from NASA and MIT conducted a successful demonstration of the event. This suggests that future astronauts will be able to easily do the check-in, while in the Sea of Tranquility, as well as make and send the self much faster than humans do with the fastest network in the world.
The findings of the experiment, the research team plans to present on June 9 at the conference on laser technologies CLEO, which will be held in California.
To create a live link with the Moon experts needed four telescopes that were in New Mexico and that the transmitted signal to a special receiver, mounted and installed on the orbiting satellite Moon.
New Wi-Fi hotspot
Each telescope has a diameter of about 15 cm and is paired with a laser transmitter, to transmit data by encoding pulses of infrared colors.
As Internet traffic signal toward the moon, the Earth's atmosphere distorts it somewhat. Therefore, all participating in the experiment telescopes signal passed through various columns of air, each with its degree of distortion.
With this approach significantly increases the chances that at least one will be able to beam the signal to reach the satellite and establish a connection with the moon.
It should be noted that communication was very good. Researchers have managed to transfer information from the Earth to the Moon skorosti19, 44 megabits per second, and download files at an incredible 622 megabytes per second!

As noted by British technology experts, this rate of 4000 times the speed with which modern radio broadcast.
Therefore, the question we are left with only one: "What's the password?"
