in addition to air, water, vegetables, and want to live on the moon also need what? In the face of this problem, what is your answer? A lot of people Shouting to stable and reliable wireless network. But the good news is that the answer is not a fable, the MIT and NASA scientists’ efforts to make wireless broadband to the moon has had certain feasibility.
it is understood that this may move to the moon for wireless broadband and we on earth, the same can be connected to the Internet, send a large amount of data, online high-definition video, and so on.
in order to implement this plan, the researchers in Mexico, respectively, set up the radio telescope for four months launch uplink signals. The internal working of the laser transmitter to 40 watts, can will load encoded information to infrared light. The month satellite, on the other hand, also install the telescope, used for the laser information and collected by point detector will laser signals into electrical signals to become information that can be read.
at present, between 384633 km distance between ground, month, has reached 19.44 MBPS data transfer rate, data download speed is 622 megabits per second. MIT Lincoln laboratory Mark Stevens said to months for high speed data transmission based on laser is quite challenging, air turbulence will also likely to lead to signal attenuation and lost. Now, set up four different radio telescopes from different azimuth beam, it may encounter interference is also different, therefore is expected to increase to accept risk.
although it only one over one billion in 40 tile signal can be received smoothly, but Steven said that one over one billion was 10 times higher than normal amount of data transmission, if just normal and stable network use, the amount of signal transmission have been more than enough.
MIT with Nasa will be on June 9 in California CLEO laser technology conference show the results of this study. It is understood that at present the technology is designed to complete the near-earth space mission, but the future is expected to further into space, also used for other planets such as Mars. Optical Society website also explains how based on laser data to send a high transmission speed.
