This paper analyzes the frequency bands and channel models that are potentially applicable in 6G networks such as: low band (below 1 GHz), mid-band (1-24 GHz) and high band (24-300 GHz) and deterministic channel modeling, stochastic channel modeling and combined stochastic-deterministic channel modeling, respectively. Given the exceptional attributes of the THz spectrum, it is imperative to develop a deeper understanding of its characteristics, part of which also constitutes the employment of innovative techniques to model and measure channel characteristics.

W artykule dokonano analizy pasm częstotliwości i modeli kanałowych mających potencjalne zastosowanie w sieciach 6G, takich jak: dolnopasmowe (poniżej 1 GHz), średniopasmowe (1-24 GHz) i górnopasmowe (24-300 GHz) oraz deterministyczne modelowanie kanałów, odpowiednio stochastyczne modelowanie kanałów i kombinowane stochastyczno-deterministyczne modelowanie kanałów. Biorąc pod uwagę wyjątkowe cechy widma THz, konieczne jest głębsze zrozumienie jego charakterystyki, czego częścią jest również zastosowanie innowacyjnych technik do modelowania i pomiaru charakterystyki kanału.
