T-Mobile US has conducted the world’s first 5G data call and video call on 600 MHz — on a live network.
T-Mobile also achieved a tri-band 5G video call with three users on different spectrum bands – 600 MHz, 28 GHz and 39 GHz.

T-Mobile US, the third largest telecom operator in the US, has conducted the 5G video call in partnership with Ericsson and Intel.

T-Mobile engineers generated a 5G signal capable of covering more than a thousand square miles from a single tower during the tests. T-Mobile accomplished a tri-band 5G video call with three users on different spectrum bands – 600 MHz, 28 GHz and 39 GHz.
John Legere, chief executive officer of T-Mobile, said: “While the other guys focus on 5G millimeter wave on a handful of blocks in a handful of cities, we’re building 5G network for everyone, everywhere.”

T-Mobile conducted the video call over low-band spectrum and using the Intel 5G Mobile Trial Platform.

T-Mobile is aiming to launch 5G in 2020, deploying 5G-ready equipment as they roll out 600 MHz Extended Range LTE, which is already live in more than 1,500 cities and towns in 37 states and Puerto Rico.
