T-Mobile touts 5G SA advances at MWC

Mobile World Congress, Barcelona — In Neville Ray’s last hurrah at MWC, he proclaimed that T-Mobile is the “leading 5G network in the U.S,” thanks — in part — to standalone (SA) 5G capabilities.

Building on its nationwide 5G SA network, T-Mobile is launching pure 5G voice calling, which the industry clunkily calls VoNR, in  six cities in the U.S. VoNR is starting in Cincinnati, New Orleans, New York, Portland, Salt Lake City and Seattle. This 5G service will cover 100 million people.

Ray also highlighted that later this year the operator is launching 4-carrier aggregation that combines two channels of 2.5GHz spectrum with two channels of 1900MHz spectrum. The mobile network operator (MNO) has already tested data calls that reached speeds of 3.3 Gbps. It will launch on the Galaxy S23, with more devices to follow.

Neither of these services could be offered without a 5G core. T-Mobile has also worked with Cisco to roll out a cloud-native converged core for its 5G SA and 4G traffic.
