Patent ID: 8005422

Claim:
A telecommunication network for establishing radiofrequency links between gateways and ground terminals via a telecommunication satellite with several spot beams, designated as a multispot satellite, said network comprising: a multispot satellite, a plurality of gateways, each gateway establishing a link with said satellite on at least Ns link channels corresponding to Ns frequency intervals [f i ; f i+1 ] 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 said satellite to which is allocated a frequency interval selected from among a plurality of frequency intervals [f′ i ; f′ i+1 ] with i varying from 0 to N−1, N being an integer strictly greater than 1, frequency f′ 0 being substantially equal to frequency f Ns , or frequency f′ N being substantially equal to frequency f 0 , each of said gateways being located in one of said Nc cells, the cells in which said gateways are located are associated with a spot beam to which is allocated a frequency interval selected from among the frequency intervals: [f′ i ; f′ i+1 ] with i varying from 1 to N−1 in the case where frequency f′ 0 is substantially equal to frequency f Ns , such that no gateway of said network is located in a cell associated with a spot beam to which frequency interval [f′ 0 ; f′ 1 ] is allocated; [f′ i ; f′ i+1 ] with i varying from 0 to N−2 in the case where frequency f′ N is substantially equal to frequency f 0 , such that no gateway of said network is located in a cell associated with a spot beam to which frequency interval [f′ N−1 ; f′ N ] is allocated.
