margin: 10px 0px; word-break: break-word; font-size: 17px;"><span style="line-height: 2em; font-size: 17px;">马斯克对“星链”的盈利前景非常看好。他认为“星链”将抢占全球3%到5%的电信市场，年收入3万亿美元。他说，我们相信这是太空探索公司创收的一种方式，将为开发越来越先进的火箭和宇宙飞船提供资金支持。</span></div><div style="line-height: 2em;

margin: 10px 0px; word-break: break-word; font-size: 17px;">1，5G所需要的那种地表大规模基建能力是中国的强项而不是美国的强项。如果美国硬搞，会花很多钱、很多年才能完成。而那时已经落后于时代。</div><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;"><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;">2，6G的特点是以卫星为基础组建互联网，而非光纤和基站。基建工作主要在太空完成，而且主要是卫星发射和部署工作。由于美国是航天强国，深空探测、遥感、操控技术都很发达，可重复火箭技术日趋成熟，芯片技术发达，美国直接过渡到6G反而相对容易。</div></div><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;">3，太空组网分为高轨道卫星和低轨道卫星。实际上目前波音的太阳能无人机已经相当成熟，可以全年不间断飞行，取代低轨道卫星。又由于地球大气层1万2千米以上就已经没有雨雪雾霾等天气变化的干扰，高轨道卫星之间和高轨道与无人机之间的通讯可以采用可见光激光，而无人机跟地面之间用无线电波。</div><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;">随着5G连接规模不断扩大，网络压力越来越大，6G一定会到来。它正在路上，一些机构和厂商已经着手研发。尽管它看起来像是5G的扩展，但随着新技术的不断发展，特别是人工智能、新材料、开源等技术的进步，它很有可能对通信业带来颠覆性的影响。</div><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;">不能忽视的一个历史怪像，移动通信每次更新换代的那个“G”似乎都遵循着一个奇怪的规律：遇到奇数的“G”命运都不太好，每次都会被下一个偶数的“G”快速代替。</div><div style="line-height: 2em; margin: 10px 0px; word-break: break-word; font-size: 17px;">走进科学小编一声长叹，些许遗憾，些许欣慰，不是不明白，世界变化快，超级大国之间在通讯科技方面孤注一掷的竞争，也许让6G会来得远远比你想象得更快！</div></div></div>
