Abstract

Bu çalışmada, gelecek nesil terahertz kablosuz haberleşme sistemleri için uygun frekans bantları incelenmiş ve farklı atmosferik koşullar altında bu frekans bantları için link hesapları gerçekleştirilmiştir. Çalışmada atmosferik koşulların değişiminden haberleşme sisteminin nasıl etkilendiği hususu dikkate alınarak makul zayıflama değerlerinde iletişim yapılabilecek 7 iletim penceresi (frekans bandı) olduğu gözlenmiştir. Bu iletim pencereleri içerisinde özellikle iç mekan ve dış mekan haberleşmesi için hangilerinin daha uygun olduğu konusu irdelenmiş ve Friis iletim denklemi kullanılarak link hesaplamaları ve gerekli doğrulamalar yapılmıştır.

Transmission windows and link budget for high speed terahertz wireless communication

Abstract

In this study, appropriate frequency bands are investigated for next generation terahertz wireless communication systems and the link budget calculations are conducted under different atmospheric conditions. Considering how the communication system is affected by the changes in atmospheric conditions in the study, it has been observed that there are 7 transmission windows (frequency bands) in which communication can be maintained at reasonable attenuation values. In these transmission windows, it is also investigated that which of them are appropriate for indoor and outdoor wireless communication and the necessary link calculations have been conducted and proved by using Friis transmission equation.
