“…The existing architectures of broadband satellite communication networks are inflexible due to its dependence mainly on the hardware. However, some of the recent works such as [114], [115], and [116] introduced the concept of using SDN for broadband satellite communication networks to improve their flexibility. Besides using it for broadband satellite communications, recently SDN was also proposed for CubeSat communications.…”

The research in the emerging space industry is becoming more and more attractive, given the increasing number of space-related applications. One primary entity of current space research is the design of miniaturized satellites, known as CubeSats, due to their numerous applications and low design and deployment cost. The new paradigm of connected space through CubeSats enables a wide range of applications such as Earth remote sensing, space exploration, and rural connectivity. CubeSats further provide a complimentary connectivity solution to the pervasive Internet of things (IoT) networks, leading to a globally connected cyber-physical system. This paper presents a holistic overview of different aspects of CubeSat missions, and provides a thorough review on the topic, both from academic and industrial perspectives. We further present the recent advances in the area of CubeSats communications with an emphasis on constellation and coverage issues, channel modeling, modulation and coding, and networking. The paper finally identifies several future research directions on CubeSats communications, namely Internet of space things, low power long range networks, machine learning for resource allocation in CubeSats, etc.

“…In such a framework, Software-Defined Radio (SDR) and Software-Defined Networking (SDN) reprensent the key technologies. Most recent contributions, published in the literature, consider the SDN-based seamless integration of heterogeneous satellite links (free-space optical and radio) [6], reconfigurable CubeSat payloads based on SDR [7], and the integration of satellite networking in the 5G ecosystem, obtained by means of SDN tools [8].…”

“…The FSO solution is, therefore, an interesting alternative to radio transmission in the framework of bulk data upload and store-and-forward applications, where, differently than in broadcasting, the continuous service availability is not an issue. Anyway, a very recent work considers, at feasibility study level, an advanced broadband feeder link solution based on the seamless integration of FSO and EHF transmission [41]. The virtual switching from FSO to EHF link (and vice-versa) is decided on the basis of the propagation conditions and managed in software manner by a network orchestrator.…”

“…In the present work, the EHF solution for the feeder link of broadcast video content delivery systems is analyzed in details, as it is regarded as a potential baseline solution capable of guaranteeing a satisfactory service continuity in the near future. The SDN-based integration of FSO and EHF technology proposed by [41] may be regarded as a potential breakthrough in a longer view perspective.…”

The exploitation of the bandwidth portions in the millimeter wave domain, namely: Extremely High Frequencies (EHFs) will open new perspectives to future satellite services, in particular for high quality TV broadcasting and multimedia content delivery. The present work aims at surveying the opportunities and challenges of EHF exploitation for broadband satellite applications in the broadcast framework. Theoretical capacity evaluation confirms that EHF satellite links can offer unprecedented data-rates, clearly superior than that actually provided by Ku and Ka-bands. However, some crucial issues are still to be solved, mainly in terms of mitigation of tropospheric propagation impairments and appropriate waveform design. Link and capacity analysis will be the basis for the investigation of future application scenarios of broadcast EHF satcoms, namely: HDTV and Ultra High-Definition TV (UHDTV), with particular emphasis to 4K and 8K video formats.Index Terms-Next generation broadcast sat systems and standards, Future technologies and services for broadcasting, Extremely High Frequency (EHF), UHDTV. 37.5-42.5 GHz (fixed) 40.5-42-5 GHz (broadcasting) W-band 81-86 GHz (fixed) 71-76 GHz (fixed) 74-76 GHz (broadcasting)The pioneering feasibility studies about EHF for satellite communications have been carried out in early 2000s in the framework of DAVID [9] and WAVE [10] experiments.
