For a while there in late 2019 and essentially all of 2020, pretty much everything T-Mobile announced regarding its 5G network was a groundbreaking or progressive move. The “Un-carrier” was the first in the US (or even the world) to adopt multiple advanced and trendsetting technologies, which were then slowly expanded, improved and refined across the country to leave Verizon and AT&T in the dust for now…
More mature and reliable than ever before, America’s largest and fastest 5G network continues to gain great new capabilities such as Voice Over 5G, aka VoNR, aka Voice Over New Radio.
This particular breakthrough has been a long time coming, and according to CNET
it has been rigorously tested for “months” in Portland, Oregon and Salt Lake City, Utah, where it’s finally available now
to the (Galaxy S21 5G using) masses in ‘selected areas’.
We’re talking, of course, about Samsung’s entire high-end handset family, due out in early 2021, with the newer and obviously faster Galaxy S22 lineup soon to join the Voice Over 5G party, alongside other undisclosed 5G devices on the list. T-Mobile of presumably more than one brand.
If you own an S21, S21+, or S21 Ultra in either of the two cities mentioned above, you may soon notice a shorter than usual delay between dialing a number and hearing your phone. That doesn’t sound like a big deal (because it isn’t), but as always, T-Mo is thinking more about the future when it sees this as another major technology milestone on its way to ubiquitous (standalone) 5G service.
In a nutshell: voice traffic can now go through the first (and still only) nationwide standalone 5G network in the US, freeing up precious resources to (eventually) enable super-advanced capabilities such as network slicing that requires a “continuous connection to a 5G core”.
No, we don’t really understand all neither of those, but we do know that 5G is the future, and making it possible for all services to rely on 5G rather than maintaining an underlying 4G LTE network and 4G core for things like voice calling is clearly another. important step in the right direction for T-Mobile.
It is perhaps needless to point out that Verizon and AT&T are both several steps behind their arch-rival on Voice Over 5G, with no clear goal of adopting the technology soon after getting off to a late start in the low and low. mid-band 5G network deployment fields as well. Oh, and their standalone 5G rollout isn’t exactly close either.
