T-Mobile USA announced that it was the first to test millimeter waves on its standalone networking (SA) 5G network, achieving downlink data rates of more than 4.3 Gbps.
The collaborative experiment with Ericsson and Qualcomm aggregated eight millimeter-wave channels, rather than relying on low-frequency or medium-frequency spectrum to anchor connections.
On the uplink, it aggregates four millimeter-wave channels, achieving data rates of over 420Mbps.
T-Mobile, currently the only operator in the US to fully deploy the SA 5G network, uses low, medium, high frequency spectrum, but is exploring millimeter-wave and potentially fixed wireless access applications in crowded areas.
In three auctions, it spent about $1.7 billion for millimeter-wave license plates.
The company used millimeter waves when it first launched 5G in 2019, but has since focused on low-frequency and medium-frequency deployments. In contrast, its rival Verizon uses millimeter waves in crowded areas.
T-Mobile technology president Ai Huaxin (Ulf Ewaldsson), said the company has always said it will use millimeter waves “where it is meaningful.”
