KT's satellite-operating subsidiary, KT SAT announced three new growth engines for its future businesses – Satellite-5G connection, blockchain-based satellite service and quantum satellite communication, at the recent CommunicAsia 2019.
Satellite-5G connection is a new telecommunication technology interworking between a 5G core network and 5G Radio Access Network (RAN) by satellite instead of fiber optic cables. KT SAT will exhibit the connection between its satellite in orbit and KT's 5G network, a technology capable of providing uninterrupted 5G services to ships and islands, and its latest global technology standards.
KT SAT's blockchain-based satellite service is a solution that provides GiGA Stealth, KT's blockchain technology, for the CCTV of ships that use an MVSAT (Maritime Very Small Aperture Terminal) service. GiGA Stealth is a blockchain-based security solution that exposes the Internet Protocol (IP) addresses of Internet of Things (IOT) terminals only to verified users.
The blockchain-based service permits only private blockchain key holders, such as ground terminals and ship owners, to remote-monitor the footage of the CCTV cameras installed on ships. Unauthorized persons are denied access to the CCTV. The launch of a pilot service is scheduled for the second half of this year.
Satellite-based quantum communication is a technology that KT SAT is developing for heightened security in data communications. When the technology is commercialized, KT SAT will be positioned to supply satellite-based data communication service to the military and government, which require higher levels of reliability for their networks.
