While all operators are moving to SA versions of 5G networks, T-Mobile US claims to be the first operator in the world to launch a national commercial 5G SA network. T-Mobile said SA deployed a 30 percent expansion of its 5G network, which now covers nearly 250 million people across 1.3 million square miles and more than 7,500 towns. Its SA network used the 600MHz spectrum in its initial phase.
“SA 5G is the real future of wireless connectivity,” said Karri Kuoppamaki, T-Mobile’s vice president of technology development and strategy. He points out that SA can achieve more transformative 5G capabilities, such as driverless steam and the more efficient Internet of Things.
“They are the first operators in the world to launch a national 5G SA network and they will have a clear advantage in 5G coverage,” said Roger Entner, founder of Recon Analytics. From a consumer’s point of view, their 5G will cover more places and more buildings. Most obviously, they will have 5G signals in more places because they no longer rely on 4G core networks to send signals. “
In addition, Karri Kuoppamaki says T-Mobile engineers reduced latency by 40 percent in tests, which is just the beginning of sA 5G’s achievable features. The SA architecture is the foundation of edge computing and network slicing, and it has the flexibility to adapt to many different deployments.
T-Mobile said the end devices needed software upgrades to use the SA network, and the first SA-enabled end devices on the T-Mobile network were The OnePlus 8 and Samsung Galaxy S20, and the software would eventually be available to other 5G terminals.
T-Mobile has previously said it will work with Cisco, Ericsson, MediaTek, Nokia, OnePlus and Qualcomm to deploy SA 5G. In terms of core networks, virtualization and containerization go hand in hand. Karri Kuoppamaki says T-Mobile’s suppliers in the core network are Nokia and Cisco. As for RAN, it is provided by Ericsson and Nokia.
