为了测试一项新的通信技术,美国航空航天局(NASA)将发射一颗围绕月球轨道运转的探测器。据悉,这项技术通过激光向地球发回通信信息,可以提供创纪录的600Mb/s的下载速度。该项计划或许还能推动提高地球上的互联网覆盖率。未来几年,商业互联网卫星服务将使用光学连接,而非现在使用的无线电连接,从而提供更大的带宽。美国弗吉尼亚州的“激光通信”公司正处于这一系统研发的早期阶段。该公司希望能够在未来4年内发射共12颗卫星。事实上,已经有一些公司提供了短程透过空气介质的光学连接。在一些校园或
To test a new communications technology, NASA will launch a probe that orbits the lunar orbit. It is reported that this technology sends back communication information to the earth through the laser and can provide a record download speed of 600Mb / s. The plan may also help boost Internet coverage on Earth. In the next few years, commercial Internet satellite services will use optical connections instead of the ones currently in use to provide greater bandwidth. “Laser Communications”, a company in Virginia, USA, is in the early stages of system development. The company hopes to launch a total of 12 satellites in the next four years. In fact, some companies already offer short-haul optical connections through the air medium. On some campus or
