Abstract
A telecommunication network for establishing radiofrequency links between gateways and ground terminals via a multispot satellite, the network comprising a multispot satellite, a plurality of gateways, each gateway establishing a link with the satellite on at least Ns link channels corresponding to Ns frequency intervals [f; f] with i varying from 0 to Ns−1 and a service area comprised of Nc cells each comprising a plurality of ground terminals, each cell being associated with a link spot beam with the satellite to which is allocated a frequency interval selected from among a plurality of frequency intervals [f'; f′] with i varying from 0 to N−1, N being an integer strictly greater than 1, is disclosed. The frequency f′is substantially equal to the frequency for the frequency f′is substantially equal to the frequency f. Each of the gateways is located in one of the Nc cells. The cells in which the gateways are located are associated with a spot beam to which is allocated a frequency interval selected from among the frequency intervals [f′; f′] with i varying from 1 to N−1 in the case where the frequency f′is substantially equal to the frequency for [f′; f′] with i varying from 0 to N−2 in the case where the frequency f′is substantially equal to the frequency f.
