Satellite multibeam signaling for multimedia services

In this paper, we constructed a scenario, using AGI's Satellite Toolkit, simulating a Geostationary Satellite and several Base Stations. The purpose was to measure and investigate the reliability of such a satellite system for data rates up to 1000 Mbps. The satellite transmitter used QPSK modulation and a multibeam antenna for accomplishing real-time satellite access and coverage over the various facilities under test. Also the validation of the certain system was performed under rain conditions, taking into consideration the need of QoS, giving results for the needed hardware to be implemented in a future construction. This system can be a part of a larger communication system involving 3G/4G, VoIP and multimedia services.
