شركة لون تابعة لشركة الفابيت (غوغل) تعلن عن مشروع توفير الإنترنت للمناطق النائية.

يستخدم المشروع مناطيد على ارتفاع 12 الى 18 كم لإنشاء شبكة لاسلكية، وتستخدم المناطيد التيارات الهوائية في الستراتوسفير وبرامج لتغيير ارتفاعها

يحتوي المنطاد على بالونين، يتم ضخ الهيليوم من البالون الرئيسي في البالون الثانوي للصعود، ومن الثانوي للرئيسي للهبوط. كما يتم استخدام الواح الطاقة الشمسية للكهرباء، وفي حال الطوارئ يتم اسقاط وحدة الجهاز التي تزن 15 كجم بمظلة طوارئ، بعد رحلة قد تستغرق 100 يوم.

سيتعين على المستخدمين استخدام هوائيات اتجاهية للارتباط مع المناطيد حتى مسافة 40 كم منه.
