Oczekuje się, że technologie dostępu radiowego wykorzystujące fale milimetrowe (mmWave), a w jeszcze większym stopniu terahercowe (THz), zapewnią znacznie większą niż obecnie przepustowość, zwłaszcza w obszarach o dużym natężeniu ruchu. Jednocześnie, silnie kierunkowe charakterystyki promieniowania anten, które muszą być wykorzystywane zarówno po stronie nadawczej, jak i odbiorczej łącza w celu przezwyciężenia znaczących strat absorpcyjnych w gazach atmosferycznych, dynamiczne blokowanie ścieżek propagacji przez duże statyczne i małe poruszające się obiekty, makro- i mikromobilność urządzeń użytkownika sprawia, że świadczenie niezawodnych usług za pośrednictwem tych zakresów częstotliwości jest złożonym zadaniem. Wyzwanie to jest dodatkowo komplikowane przez rodzaj spodziewanych aplikacji przewidzianych dla tych systemów, które z natury wymagają gwarantowanych parametrów jakościowych w interfejsie radiowym. W artykule omówiono wybrane zagadnienia dotyczące wykorzystania, modelowania propagacji i wpływu fal z tego zakresu na architekturę przyszłych sieci mobilnych.

Radio access technologies using millimeter waves (mmWave), and to an even greater extent terahertz (THz) bands, are expected to provide significantly higher throughput than today in high traffic areas. At the same time, the highly directional radiation patterns of the antennas, which must be used on both the transmit and receive sides of the link to overcome significant atmospheric absorption, the dynamic blocking of propagation paths by large static and small moving objects, and the macro- and micromobility of user equipment (UEs) make providing reliable services over these frequency bands an extremely complex task. This challenge is further complicated by the type of applications envisioned for these systems, which inherently require guaranteed quality of service at the radio interface. This paper discusses selected issues regarding the use, propagation modeling and impact of mmWave ant THz range on the architecture of future mobile networks.
