搞6G是OK,因為5G缺點實在太多
但搞衛星真的很謎
同樣的技術,有線光纖的通訊量,必定比幾萬公里衛星軌道的傳輸穩定、雜訊低、效率好
6G光纖一定比6G衛星穩
因為在光纜內部的環境實在太穩定了,又可以不斷有中繼站加強訊號
效率怎麼可能是一堆折射的大氣,距離又隨便幾萬公里起跳的衛星傳輸可比的
衛星還要自己太陽能發電,貴+貴+貴+沒效率
而且人類的居住趨勢是愈來愈都市化,不是愈來愈分散
這樣鋪光纖搞硬體基礎設備,一定比搞衛星便宜有效率
衛星頂多開發新的利基市場而已,他不會是地球文明通訊的主要手段
我甚至很難想像到底要開發什麼利基市場,可能把貨輪全無人化、
海洋探勘無人化之類的吧?這聽起來也是很大一塊就是了
Google實驗很久過了都放棄了,如果其他的科技與社會環境還沒有跟上
衛星很容易會搞到無法回本
怎麼會變成在炒衛星,完全看不懂
希望美國的主事者不要被詐騙,這種文明國戰如果錢燒錯了真的會很挫
