All of the US carriers have now launched some form of 5G cellular network. But what exactly is 5G, and how fast is it compared with 4G? Here are the facts we know so far. It’s messy. It’s very early days. And if you like new technology, it’s very exciting. The early 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 800 feet from a cell site, which means there isn’t much coverage. All four carriers are waiting for upgrades to their base stations that will improve coverage, speed, and reliability. Around the end of this year or the beginning of 2020, AT&T, Verizon, and T-Mobile all intend to launch 5G networks that use existing 4G spectrum, which will have slower speeds but broader coverage.
