الأقمار الصناعية تنافس أبراج الاتصالات.. من يكسب معركة المستقبل؟

Back

ما يعرفه ريفو عن الخبر

  • تسمح تقنية الاتصال المباشر بالأقمار الصناعية للهواتف المحمولة العادية بالعمل في المناطق النائية والمنخفضة الكثافة السكانية.
  • تعمل الأقمار الصناعية كبديل لتغطية الفجوات الجغرافية في المناطق التي يصعب فيها بناء أبراج أرضية.
  • تتجه صناعة الاتصالات نحو بناء شبكة هجينة تجمع بين الأبراج الأرضية لتوفير السعة العالية والأقمار الصناعية لتوسيع نطاق التغطية.
  • يقلل التعاون بين مشغلي الأقمار وشركات الاتصالات من تكاليف البنية التحتية ويقلل الحاجة إلى المنافسة المباشرة في السوق.

تتجه الاتصالات المحمولة نحو مرحلة جديدة يصبح فيها الفضاء امتدادا للشبكات الأرضية، مع قدرة الأقمار الصناعية على إيصال الإشارة إلى الهواتف مباشرة، وظهور منافسة جديدة على النفوذ في سوق الاتصالات.
