華為被「五眼」情報聯盟視作威脅 面臨抵制 New Zealand spy agency rejects carrier's plan to use Huawei 5G equipment為何中國的華為 (Huawei Technologies)讓美國如此怕怕?

在新西蘭拒絶華為進入該國5G網絡投標後,英國也說對華為有「技術擔心」,西方五國情報聯盟似乎開始採取行動。

New Zealand blocked its top telecom firm from using Huawei equipment for its 5G mobile network, dealing another blow to the Chinese tech company's ambitions to become a leader in the next generation wireless technology.





基本上,華為是國營企業披上私營面具,而且是中國大到(或好到)不能倒的樣板企業。



知情人士稱,美國政府已向其海外盟友發起一項特別行動,試圖說服這些國家的無線及網路提供商不要使用中國華為技術有限公司的通信設備。

The U.S. government is trying to persuade wireless and internet providers in allied countries to avoid telecommunications equipment from China’s Huawei Technologies as they prepare to buy new hardware for 5G.

全球通吃的衛星連線計畫:半世紀的夢想:Motorola為主的公司Iridium 、SpaceX和中國壯志




RFI 華語 - 法國國際廣播電台據中國央視一項報道稱,中國2019年將在戈壁沙漠的酒泉衛星發射中心,在長征系列火箭上搭載首個WIFI專用人工衛星發射至太空。並以此為起點,中國計畫截止到2026年發射272顆衛星至地球衛星軌道,向全世界提供免費網絡服務。......
據中國央視CCTV介紹稱,該計畫將幫助目前地面網絡信號無法覆蓋的地方接入網絡。尤其在地形複雜無法安裝網絡基礎設施的情況,衛星網絡將起到極大的作用。消息沒有提及中國建議免費提供WIFI的條件以及國際反應。

Tomas Tso SpaceX在11月15日已獲得美國聯邦通信委員會同意再發射7,518顆衛星,連同2018年3月份已經核准的4,425顆衛星----那麼,這個名為Starlink的完整衛星互聯網系統將會有12,000個衛星在不同的高度"協同運作";2024年完成6,000顆衛星的發射!!

7,518顆衛星運行高度在335至346公里之間;先前核准的4,425顆衛星運行高度在1,110至1,325公里的軌道-----兩顆測試衛星--TinTin A和B已經於二月份發射升空;

未來的太控會很擁擠的!!
