5G ve Ötesi Haberleşme Teknolojilerinde Karasal Olmayan Ağ Konseptleri

Abstract

5G ve ötesinde kullanılan mobil iletişim sistemleri, geniş kapsama alanlarında yüksek kapasiteli, güvenilir ve düşük gecikmeli hizmetler sunacaktır. Şu anda mobil karasal ağlar yaygın olarak kullanılmakla birlikte, ilerleyen dönemde bu ağların yerini karasal ve karasal olmayan ağların birlikte çalıştığı hibrit ağ çözümlerinin alması beklenmektedir. Karasal ağların sinyal seviyeleri zayıf olduğunda ve coğrafi zorlukların engelleyici olduğu durumlarda; bu hibrit ağ çözümlerinin kullanıldığı en son teknolojiler tamamlayıcı çözümler olarak sunulmaktadır. Bu çalışmanın ana motivasyonu, dijital ayrılık ve erişim sorunlarının çözümü için hibrit ağ yapılarının kullanımının önerilmesi olarak belirtilebilir. Bu çalışmada hibrit kablosuz ağların farklı sistem mimarilerine göre tasarım optimizasyonları ve performans analizleri verilerek çeşitli karasal olmayan ağ teknolojileri karşılaştırılmıştır.

Non-Terrestrial Network Concepts in 5G and Beyond Communication Technologies

Abstract

Mobile communication systems used in 5G and beyond will provide high-capacity, reliable and low-latency services within wide coverage areas. Currently, terrestrial networks are widely used, but it is expected that these networks will be replaced by hybrid network solutions where terrestrial and non-terrestrial networks operate together. These hybrid ones can perform cutting-edge complimentary solutions when the traditional networks have weak signal levels and geographical difficulties. The main motivation of this study can be stated as the increasing use of hybrid network structures for the solution of digital divine and access problems. In this study, design optimizations of hybrid wireless networks according to different system architectures and performance analyzes are given and various non-terrestrial network technologies are compared.
