5G 위성 통합

The convergence of satellite services with 5G holds the promise of revolutionising communications by offering increased connectivity in underserved areas and boosting network resilience. This synergy between satellites and 5G is driven by the growing need for reliable connectivity, particularly in rural and remote areas where traditional terrestrial infrastructure is absent or limited.

• Global Coverage
• Resilience
• New Markets

Although Non-terrestrial Network (NTN) 5G is still in its infancy, a number of initiatives are underway (industrial consortia, ESA, research projects).

The main challenges remain related to the maturity of the end equipment, the cost of the infrastructure required for production and maintenance, and the regulations and cooperation between the various segments.

3GPP standardisation since Release 17 has enabled 5G to take into account NTN communications, offering the possibility of low-speed communication, the Internet of Things and recent improvements for broadband.
