Wi-Fi on the moon is now as fast as the Wi-Fi in your living room
现在月球上的wifi已经跟你家的一样快了
Researchers at NASA and MIT have figured out how to beam wireless
connectivity from a ground base in New Mexico
Timothy McGrath, GlobalPost
Life on the moon just got a whole lot more awesome. Sure, you’ve got to wear
a spacesuit and there’s not much to do in the way of recreation and
nightlife.
在月球上的生活变得更有意思了。当然你得要穿太空衣,而且没什么娱乐和夜生活
But that’s all okay now, because there’s Wi-Fi.
但是现在一切都没问题了,因为那里有wifi
Researchers at NASA and MIT have figured out how to beam wireless
connectivity from a ground base in New Mexico to the moon using
telescopes and lasers.
研究员找出利用雷射和望远镜做无线传输的方法
It’s as cool as it sounds.
Here’s how it works. The transmission utilizes four separate telescopes
connected to a laser transmitter that feeds coded pulses of infrared light
through it. Those signals travel toward a satellite orbiting the moon.
Researchers have managed to make a connection and transfer data at a speed
approximating slower Wi-Fi speeds on Earth.
它的运作方式是:利用四台望远镜把红外线雷射打到绕月卫星上面。
现在的连线速度已经跟地球上的慢速wifi(比如说台湾)差不多了
It’s no easy feat, and it doesn’t work every time.
“Communicating at high data rates from Earth to the moon with laser beams
is challenging because of the 400,000-kilometre distance spreading out the
light beam,” said Mark Stevens of MIT Lincoln Laboratory. “It’s doubly
difficult going through the atmosphere, because turbulence can bend
light-causing rapid fading or dropouts of the signal at the receiver.”
考虑到40万公里的距离和大气扰动,月球和地球间的高速传输并不容易。
Using four telescopes increases the chance that one of them will successfully
hit the satellite.
利用望远镜可以增加光打到卫星的机会。
The scientists-turned-Wi-Fi-troubleshooters will present their research
at the CLEO laser technology conference on June 6.
Such good news for life on the moon. We can now power-watch “West Wing.”
现在可以在月球上看影片了

觉得台湾网络慢的人不考虑去月球上打卡上ptt吗?
讨厌4G限速或是iPhone频宽不支援的也可以上月球wifi吃到饱
