Abstract<br />

The technology of telecommunications is a constantly developing technology.<br />

As the number of users increases and their demands grow, old systems have to be<br />

upgraded and new progressive ideas must be put into practice. High altitude<br />

platforms (HAPs) are an ambitious attempt in this direction, a technology that when<br />

fully implemented will be capable of providing advanced services to a variety of<br />

users.<br />

However, in order to ensure efficient operation and coexistence with present<br />

systems, it is necessary to conduct an interference analysis. Beyond the theoretical<br />

approach, simulation procedures are very valuable in cases like this, because they<br />

can lead us to important conclusions about the nature of the problem and its possible<br />

solutions.<br />

Keywords<br />

Interference, fixed satellite service (FSS), high altitude platform stations<br />

(HAPS), 47/48 GHz, simulation, Visualyse.<br />
