The paper carries out a preliminary assessment of how mobile satellite broadcasting (MSB) systems can increase their capacity potential with a high degree of flexibility and, at the same time, remain on par with wireless terrestrial counterparts. As argued in this work, a promising way forward in this regard is the migration from the conventional single polarization per beam to an advanced dual polarization per beam architecture, also benefitting from recent advancement in multibeam antenna techniques. This work summarizes results of recent studies on dual polarization MSB from a system, interference, antenna, channel, capacity, and FEC uncoded MIMO performance perspective, highlighting along the course the major milestones and challenges.
