The ITU Radiocommunication Assembly considering a) that interference may impose a limit on the number of satellites which operate in the same frequency band in the same part of the geostationary-satellite orbit (GSO); b) that the number of satellites using the GSO for operational purposes has grown and will continue to grow significantly in the next few years; c) that frequency band utilization methodologies are considered as a means of reducing inhomogeneity between networks in the frequency dimension; d) that the more heterogeneous the types of carriers concerned, the higher are the levels of internetwork interference, and the more complex is the coordination process; e) that methods of spectrum utilization can, in some circumstances, increase the likelihood of accommodating additional users; f) that the use of frequency band utilization methodologies will lead to the most efficient use of the radio frequency spectrum and the GSO.
