“…Given the abovementioned differences, it is impossible to apply the existing visible ray tracing techniques to solve the signal propagation in UHF directly. Therefore, it is necessary to carry out a detail study on the transmission mode of electromagnetic wave in the planted forest in order to achieve a thorough research on the transmission law of UHF in it [6,14].…”

Since the environment in the forest is relatively complicated and there's a necessity to avoid the dead zone of signal diffraction when laying wireless sensor in the forest, the integration of SBR and UTD is applied to study the impact of 2.4GHz radio-frequency signal on the path loss characteristics in the forest. This paper achieved the ray location from the receive pint to field point by using back-ray tracing method and computed the response electric field relative to each ray by using UTD. Take the poplar planted forest for instance. The measured value and simulated value were compared, finding good consistency between them, which indicates that SBR and UTD can effectively predict the path loss characteristics in the forest. Streszczenie. W artykule przedstawiono zagadnienie rozprowadzania pola sieci bezprzewodowej w obszarze leśnym. Zastosowane rozwiązania (SBR, UTD) pozwoliły na skuteczną lokalizację i przesył informacji przy zastosowaniu fal 2.4GHz. Wyniki symulacyjne porównano z wynikami pomiarów, przeprowadzonych w lesie topolowym. (Badania hybrydowego systemu śledzenia fal promieniowania 2.4GHz w sztucznym lesie).
