T-Mobile says it has completed the world’s first 5G video call and data session on 600 MHz during a test on a live commercial network in Las Vegas with the aid of Ericsson and Intel. The carrier, which is trailing the 5G efforts of AT&T and Verizon, also says it completed a 5G video call with three users on different spectrum bands: 600 MHz, 28 GHz and 39 GHz.
