AT&T Launches More Capable 5G Nationwide

AT&T has officially launched 5G SA (Stand-Alone) network technology nationwide. Like most US carriers, AT&T initially launched 5G using the NSA (Non-Stand-Alone) version of the technology, which relied on the existing 4G LTE network for some functions. Aside from not needing the 4G network, 5G SA unlocks several advanced capabilities of 5G, including faster upload speeds, ultra-low latency, ultra-high reliability, and edge functions. T-Mobile made the same announcement in 2020. Verizon has yet to formally announce nationwide 5G SA, although observers have spotted Verizon 5G SA running in several parts of the country. The launch of 5G SA is related to the launch of 5G RedCap (Reduced Capability), a simpler version of 5G designed for less powerful (and less demanding) devices, including smartwatches. AT&T confirmed that Apple's newest smartwatches use 5G RedCap, which is likely spurring the current rollouts of 5G RedCap and 5G SA by AT&T and Verizon.
