South Korea’s KT Corp. said on Monday it and U.S. partner Verizon successfully demonstrated an international video call using 3-D holograms over the next generation of wireless network or 5G.
The demonstration was made over a 28GHz 5G network connected to each company headquartered in Seoul and New Jersey.
The two has worked on standards for 5G wireless connection since February of last year.
A low-end tablet was used in the demonstration of a holographic video call, making it closer to a commercial service, KT said.
The international leased line used for the demo call was driven by software-based infrastructure (SDI), which is core technology for 5G communication. While using an orchestrator system that automates SDI technology, the time required to build an international leased line was reduced to 10 minutes from 10 days.
In the past, a large number of people had to go to the field to configure the leased line, but with SDI technology, network equipment could be virtualized in software and centrally controlled.
The two companies will jointly propose an international standard for SDI orchestra interworking technology and plan to expand their network ecosystem.
