The test results will influence the development of fixed broadband and low-latency 5G broadcasts.
T-Mobile announced a successful test using its production standalone 5G mmWave network. T-Mobile calls the results of the test unprecedented for the United States.
Through collaboration with Ericsson and Qualcomm Technologies, T-Mobile was able to combine eight channels in the millimeter wave band, allowing it to achieve download speeds of 4.3 Gbps without the need to use low- or mid-band spectrum to anchor the connection. T-Mobile also combined four millimeter wave channels to form an uplink, which reached data rates of 420 Mbps.
The use of 5G technology in the millimeter wave range can provide incredibly high speeds as it forms a huge capacity. However, such a signal does not pass through obstacles very well, which makes such networks less attractive to mobile phone users who do not sit in one place.
To solve this problem, T-Mobile has implemented a multi-band spectrum strategy, using low frequencies to cover the entire country and mid and high frequencies (Ultra Capacity) to provide high speeds to virtually every user.
T-Mobile says 5G mmWave technology in 5G SA can be used in crowded areas such as stadiums and potentially for fixed wireless needs.
“We have been and continue to be industry leaders—we launched the very first, fastest standalone 5G network nationwide—and now we continue to push the boundaries of wireless technology,” said T-Mobile President of Technology Ulf Evaldsson. “We have always said that we would use millimeter wave where it makes sense for us, and this test allows us to see how this spectrum can be used in different situations, for example in crowded areas or to power systems such as fixed wireless combined with standalone 5G.”
T-Mobile’s 5G network reaches more than 330 million people across 5 million square kilometers, more than AT&T and Verizon combined. In addition, approximately 300 million people across the United States have access to T-Mobile’s Ultra Capacity 5G service.
