Google to use balloon to provide free internet access or poor areas


Google「Project Loon」升空,無遠弗屆,填補偏遠地區的數位落差

Google 公布秘密研發18個月、協助無網族上網的最高機密 Project Loon。

科學家在紐西蘭基督城上空成功進行能提供網路的氣球飛行測試,氣球彼此間可以連線,也會與當地網際網路提供業者連線,藉此組成一個能四處移動的高空網路連線網。

半透明氦氣球充飽氣後,長度相當於一架小輕型飛機,飛行在距離地面約20公里處。一旦進入平流層,高度將是一般民航機的一倍高,地面上肉眼根本看不到。

每個氣球所能提供的網路服務面積是1,250公里,範圍相當於兩個紐約市面積大小,此外且不受高山,或是峽谷等各類地形的影響。

氣球之所以能提供網路,在於與當地 ISP 連線的地面工作站,會對飄浮於高空中、靠太陽能板發電的氣球發送訊號。這些氣球彼此之間也能連線,在天上形成一個綿密的網絡。在地面上的使用者只要家裡安裝有網際網路天線,就能在氣球臨空飄過時收發訊號。

目前有約50名 Canterbury area of New Zealand 網友參與該實驗的測試,倘若Project Loon 一切順利,各國未來可望省下架設光纖電纜的昂貴費用,與大幅增加非洲和東南亞的上網人口。除了提供網路,這些氣球也能在現有通訊基礎建設因天災受損時派上用場。

由發想出無人駕駛自動車與 Google 眼鏡的 Google 機密實驗室 X lab 研發的 Project Loon,目前仍處於初步階段,但 Google 希望終有一日能讓數千個氣球飛行於平流層,提供世上偏遠地區網際網路,以填補全球48億無網路人口與 22 億網友間的數位落差。
