Cost-efficient design of hybrid network for video transmission in tropical areas

The necessity of providing broadband connectivity to lowdensely populated areas has given rise to a big interest for hybrid networks, specially those composed of a satellite backhaul and a wireless terrestrial network. In this paper, we focus on a DVB-S2/RCS system with Adaptive Coding and Modulation (ACM) for the satellite link and a Wi-Fi network for the indoor terrestrial wireless link. Figure 1 depicts the considered scenario, which reproduces the hybrid network used to give service to small villages along the Amazon River [1]. The video stream is transmitted by the video stream server to the satellite transmitter, which broadcasts it to the satellite network.
