AT&T CEO Randall Stephenson said in January that AT&T’s first mobile 5G device would be a “puck.” Today AT&T took the wraps off that gadget: It’s the Netgear Nighthawk 5G Mobile Hotspot.

AT&T disclosed the news in its announcement that it successfully completed “the world’s first millimeter wave mobile 5G browsing session with a standards-based device on a mobile 5G network” last night in Waco, Texas.

“The browsing session was on what will be a commercially available 5G device – the Netgear Nighthawk 5G Mobile Hotspot,” AT&T said. “This is the first standards-based mobile 5G device in the world able to access a live millimeter wave 5G network.”

An AT&T spokesperson confirmed to FierceWireless that the Nighthawk 5G Mobile Hotspot will be AT&T’s first mobile 5G device, and that it is the “puck” Stephenson was referring to in January.
