Radio Wave Propagation Conditions for Terrestrial Radiocommunications in the EHF Band

摘要

Designing an effective radiocommunication system which operates at EHF band is not an easy task. To achieve this goal it is important to take the meteorological effects into account. It is noteworthy that a combined impact of many weather factors should be considered when transmission frequency exceeds 10 GHz. The understanding of these mechanisms as well as their mitigation is a key to design and build efficient wireless communication systems operating at EHF. Therefore, in this study an influence of different weather conditions on effectiveness of the transmission is discussed. In addition, some possible solutions of reducing these meteorological effects are mentioned. Finally, the simulation results which confirm the usefulness of the EHF band are presented. It is important to note here that the main concern for this study is the fixed and mobile short-range terrestrial radiocommunication and all considerations included in this article are focused mainly on this part of the wireless communication.
