Satellite has been regarded for a long time as a mere relay orbiting around the Earth, suitable for global-coverage broadcasting applications. As the terrestrial wireless networking technology evolved, the role of satellite communications becomes more and more marginal, mainly due to their lack of flexibility. In order to be effectively integrated with terrestrial network infrastructures, the Space segment should be able at reconfiguring itself in some manner. Indeed, for users, developers and service providers, a payload designed 20 years ago – this is the average lifetime of an in-orbit satellite – is clearly obsolete.

Unfortunately, if nonprogrammable hardware is used on-board, nothing can be done in order to change payload architecture and functionalities. In such a perspective, the progressive “softwarization” of digital communications and networking can provide an answer. This seminar aims at reviewing the state-of-the-art panorama about the softwarization of satellite communications, meaning with this term both the implementation of software-defined-radio based payload, provided with features like frequency agility, reprogrammable transmission waveforms and coding, and techniques for higher-layer network management, like resource virtualization and slicing.

In the framework of a renewed “Space 2.0” vision, softwarization will definitely augment flexibility, reconfigurability, energy efficiency and resilience of the Space segment in the perspective of the future interaction and integration with 5G (and beyond) terrestrial deployments.
