Dr. Thierry Abraham, Chief Strategy Officer, SatixFy
Direct to Cell phone LEO constellation is not a dream anymore and the race is on. Several announcements were released recently such as SpaceX partnering with T-Mobile to provide basic text service across parts of the U.S., and Thales, Ericsson and Qualcomm teaming-up to develop 5G non-terrestrial networks using low-Earth orbit (“LEO”) satellites. While these offerings provide basic direct-to-cell satellite service for text messaging services, full-scale voice and data services desired by consumers will require the use of advanced chip technologies to address current limitations such as multi-beam digital Beam-forming and On-Board-Processing technology. The presentation summarizes what is required to enable higher data-rate Direct-To-Cell services via satellite, when it can be deployed and how SatixFy is poised to Enable Direct-to-Cell 5G Non-Terrestrial Networks.

Dr. Barry Evans, Professor, University of Surrey
Currently satellites are being studied in standards bodies for integration into 5G networks. Several demonstrations have been made and an NTN standard for New Radio (NR) and narrow band IoT is approaching completion. Already research has commenced on 6G in which satellites will be an integral component in what we term a unified approach. This paper outlines some of the current work in the satellite integration phase in 5G as a precursor to the 6G standardization which will commence in 2025. The paper outlines the vision for 6G and brings out some key areas that satellite will play a part in. It outlines some of the key research challenges ahead for satellites if they are to achieve a unified 6G network with terrestrial networks.

Dr. Alban Duverdier, Deputy Scientific Director, MESR
Since the early 2000s, satellite telecommunications have evolved significantly with the deployment of high throughput satellite systems offering Terabps capacity. Most often, operators and analysts evaluate this system capacity adding the forward and return data rates, obtained by multiplying the number of satellites by the available bandwidth, the frequency reuse factor and a typical spectral efficiency for each link. After presenting this first level solution, the paper proposes a methodology to evaluate HTS system capacity in three steps: IP throughput from link budget analysis, capacity obtained at the satellite level, influence of system configurations (users, gateways, services).
Alban Duverdier joined CNES in 1998. He is seconded to Ministry of Higher Education and Research as deputy scientific director for “mathematics, physics, ICT, nanoscience” since 2020 and was deputy head for “space policy and defense” from 2018 to 2020.

Dr. Sungtek Kahng, Professor, Incheon National University
As the generation of mobile communication develops as is slated to be hooked up to satellite communication, the importance of digital or software is highlighted more and more as a fad that the notion of SDR will work things out. Communication is a product of impartially integrating the fields of software and hardware. In order to stop the waste of time in finding causes of failure in communication by scrutinizing the software of a system, this paper as a problem diagnosis report shares an idea that problems in the hardware of the system end up with malfunctions in satellite communication. Since the portals of the satellite wireless payload are taken up by the antenna and the filter, which account for forming the wireless link, the consequences of problematic RF components are investigated. Physical errors in the components are brought up to demonstrate a functional degradation like weakened signals.
Sungtek Kahng received the Ph.D. degree in electronics and communication engineering from Hanyang

The integration of NTN into terrestrial cellular networks is another important enabler in achieving truly global coverage, since it facilitates seamless roaming between cellular and non-terrestrial networks with a single device. This presentation aims to bring together researchers of relevant fields, to discuss the latest results and progress of NTN from different perspectives (academia,industry, operators, and regulatory authorities). These discussions will inspire the evolution of NTN toward 6G.

5G in Japan
Dr. Hiroyuki Tsuji, Director, Space Communication Systems Laboratory, National Institute of Information and Communications
At present, discussions on information and communication technologies for Beyond-5G/ 6G are accelerating. In the field of space communications, satellite communications are becoming more advanced and active, and it is expected that an advanced information and communication network will be realized that links the earth and space with satellites. In the Beyond 5G/6G era, spatial network expansion is required, and advanced communication with mobile devices called non-terrestrial networks will become important.
This paper describes the efforts and the status of R&D regarding the developments of satellite communications and non-terrestrial networks (NTN) toward Beyond-5G/6G in Japan.
