Analiza propagacyjna łączy typu punkt-punkt pracujących w paśmie Ehf dla warunków klimatycznych Europy Środkowej

Omówiono metody szacowania tłumienia propagacyjnego w pasmie EHF (30-300 GHz), a także przeanalizowano możliwości wykorzystania tego pasma na potrzeby komunikacji typu punkt-punkt (radiolinie). Całość badań przeprowadzono dla warunków klimatycznych specyficznych dla Europy Środkowej, a więc słusznych także dla Polski.

In the article, the methods of obtaining the propagation attenuation for the EHF Band (30-300 GHz) have been presented. Additionally, the usefulness of this particular band for short range point-to-point communications (e. g. radio relay systems) have been researched. All the analysis have been carried out for climatic conditions typical for Central Europe (which are also valid for Poland).

Radio wave propagation conditions for terrestrial radiocommunications in the EHF band

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 shor--range terrestrial radiocommunication and all considerations included in this article are focused mainly on this part of the wireless communication.
