Abstract
Current societal needs demand for global high-speed networks. Toward this regard, 3GPP has included in its release 17 Non-Terrestrial Networks (NTN). In order to meet the strict requirements of 6G networks, Very Low Earth Orbit (VLEO) and Low Earth Orbit (LEO) satellites will play a key role. However, optical fibers also can be used for transmitting data at high speeds. Unfortunately, their refraction index is much larger than the satellite one (i.e. free space), but the large altitude of satellites penalize them. So, there is a distance in which it will be better to use one or other transport network. This work determines this distance. For a fair comparison in terms of bandwidth, it has been assumed that the LEO/VLEO satellites should be optical too. Furthermore, it has been developed a parallel algorithm to collocate an optical LEO/VLEO ground station to provide 6G service. As a paradigmatic case of study, it has been considered the Iberian peninsula. EUMETSAT has provided the images and the parallel program uses the OpenMP libraries for Python.
