Summary The first true multitechnology communication system is 5G, which is expected to have a large impact on society and industry. The European Commission funded H2020 5G‐PPP Phase 2 project SaT5G addressed the plug‐and‐play integration of satellite communication into 5G. One of the SaT5G use cases corresponds to the delivery of 5G connectivity services to moving platforms such as aircraft via GEO/MEO satellite backhauling. With focus on this use case, this paper elaborates on the practical implementation and measurement results obtained within the 5G Aero testbed developed as part of the SaT5G project. The 5G Aero testbed activities focus on the next generation of connectivity and content distribution services to airplanes through satellite and terrestrial integration in 5G at the user, control and management planes. Software‐defined networking (SDN) and network functions virtualisation (NFV) are key enablers to develop a powerful end‐to‐end testbed that can accelerate the adoption of multi‐access edge computing (MEC) for the next‐generation in‐flight entertainment and connectivity (IFEC) services, which use geostationary (GEO) and medium Earth orbit (MEO) satellite backhauling technologies. Hence, measurement results obtained from both over‐the‐air demonstration over the O3b MEO satellite constellation and in‐lab validation over an emulated GEO satellite link are presented, towards the next‐generation 5G‐enabled IFEC services.

“…Satellite communication systems have been greatly developing in the domain of broadcasting, navigation, rescue, and disaster relief because of their potentiality to provide wide coverage and achieve high data rate transmission (An et al, 2015). For most cases in previous generations, satellite systems were considered completely independent from the terrestrial communication (Khalili et al, 2019). However, there exists a potential shortcoming that the satellite system will degenerate in the presence of shadowing, which occurs when the line-of-sight (LOS) link between the satellite and the terrestrial user is blocked by obstacles (Ruan et al, 2018;Cai et al, 2019).…”

The integration of satellite and terrestrial communication systems plays a vital role in the fifth‐generation mobile communication system (5G) for the ubiquitous coverage, reliable service, and flexible networking. Moreover, the millimeter wave (mmWave) communication with large bandwidth is a key enabler for 5G intelligent rail transportation. In this paper, the satellite‐terrestrial channel at 22.6 GHz is characterized for a typical high‐speed railway (HSR) environment. The three‐dimensional model of the railway scenario is reconstructed and imported into the Cloud Ray‐Tracing (CloudRT) simulation platform. Based on extensive ray‐tracing simulations, the channel for the terrestrial HSR system and the satellite‐terrestrial system with two weather conditions are characterized, and the interference between them are evaluated. The results of this paper can help for the design and evaluation for the satellite‐terrestrial communication system enabling future intelligent rail transportation.

“…Efficiency and security are the advantages of such links, but the cost is still high. EU 5GPPP Phase 2 SAT5G project proposed network architecture for the fifth-generation mobile communications empowered by satellite links to support emerging mobile video delivery (HTS) [7] with lower cost and energy consumption. It is foreseen that V2X networking can achieve much wider coverage and higher reliability by integrating the satellite link and terrestrial links.…”

In the vision of intelligent transportation, vehicles are expected to feature with advanced applications, such as automatic road enforcement, dynamic traffic light sequence, and autonomous driving. Therefore, real-time and fast dynamic information exchanges are required, and vehicle-to-everything (V2X) communications are highly demanded. In this work, the channel characteristics of vehicular communication are analyzed in the millimeter-wave (mmWave) band at 22.1-23.1 GHz. Specifically, two types of links (the satellite link and the terrestrial link) are considered in urban and highway scenarios with different weather conditions. The ray-tracing simulator together with calibrated electromagnetic parameters is employed to practically generate wideband channels. The key channel parameters of each link including the received power, Rician K -factor, root-mean-square delay spread, and angular spreads are explored. The co-channel interferences between the two links are analyzed as well. The observations and conclusions of this work can be useful for the design of V2X communication technologies.
