The publication notes that T-Mobile isn’t the first carrier to promote different 5Gs: And while yet another 5G brand standard is confusing, it’s not without precedent. Verizon has been differentiating between its low-band 5G (also called “5G”) and its mmWave coverage (“5G UW,” or ultra-wideband) since it started rolling out those networks years ago. AT&T does something similar, too, referring to low-band 5G as “5G,” while its mmWave networks are “5G Plus.”
