SYSTEM AND METHOD FOR EFFICIENT FREQUENCY USE IN A HYBRID MULTI-SPOT SATELLITE BROADCASTING SYSTEM

摘要

A hybrid system multibeam broadcasting satellite comprising at least one satellite (S; S1; S2) capable of multibeam broadcasting of beams in bandwidths of different frequency and respective (F1; F2; F3), each of said beams adapted to be broadcast towards a respective terrestrial repeater (R1; R2; R3) having means for receiving, processing and forwarding said beam in a wide frequency band that is different from the bandwidth of the received beam, characterized in that said satellite broadcasting at least a first, a second and a third beam, each beam directed respectively to a first, second and third terrestrial repeater, wherein, said first terrestrial repeater re-transmits said first beam using a bandwidth which is a combination of widths respective band of said second and said third beam.
