5G stands for fifth-generation cellular wireless, and the initial standards for it were set at the end of 2017. But a standard doesn’t mean that all 5G will work the same—or that we even know what applications 5G will enable. There will be slow but responsive 5G, and fast 5G with limited coverage.

arly 5G rollouts are more like a public beta test than a final product. AT&T, Verizon, and T-Mobile are all using technologies that only travel about 600 feet from a cell site, which means there isn’t much coverage.
