For years, I’ve been writing about 5G and telling you why you shouldn’t invest in it. The bottom line has been that 5G simply hasn’t been able to deliver on its high-speed, low-latency promises. But, finally, things have changed. Today, 5G can at last deliver much better performance—sometimes—with certain versions of 5G only offered in specific places.
First things first. 5G is an awful name. It covers multiple kinds of cellular data networks. For example, Verizon 5G Ultra Wideband swears it can deliver 1Gbps speeds with less than 10 milliseconds of latency. What Verizon doesn’t tell its users is that only the mmWave version can deliver that performance, it has a range measured in yards, and it can be stopped dead in its tracks by a pane of glass. In short, its performance is more like Wi-Fi than any kind of cellular data network.
