Samsung officials this week touted a successful 5G live video call featuring the Korean tech giant’s prototype 5G tablet.

Verizon CEO Lowell McAdam and Chang-Gyu Hwang, his counterpart at Korean telecom giant KT, spoke on a video call between Minneapolis and Seoul during Sunday’s Super Bowl LII.

The demonstration used Samsung 5G technology in both cities, including 28 GHz 5G access units, 5G home routers, virtualized RAN and virtualized core network.

The tablet, meanwhile, can run on 5G networks at multi-gigabit per second speeds. The device can also operate on 4G LTE networks and facilitate data session handovers between 4G LTE and 5G.

“This demonstration conducted today with KT and Verizon represents a huge milestone for us, showing our contribution to the development of early 5G global specifications and 3GPP NR, and spotlighting the next generation Samsung technologies that let operators implement robust new services,” Woojune Kim, Samsung Electronics’ North American head, said in a statement.

Verizon also tested 5G virtual experiences during the Super Bowl, both at the game and at a co-working facility in New York.

“By working closely with industry leaders like KT and Samsung, we are finally making 5G a reality,” added Ed Chan, the carrier’s chief technology architect.
