There's been a lot of buzz about 5G over the last year—much of it, sadly, none too coherent. Today, we're going to take a detailed, realistic look at how we can expect 5G to improve cellular broadband, with a focus on the impact we might be able to expect on gaming. Surprise: the news is actually not bad!

Before we can talk about what to expect from 5G, we need to talk about what 5G actually is—and isn't. 5G, short for "fifth generation," is the next cellular communications protocol. 5G is not, specifically, any given frequency or band. There are two major bands 5G can operate on—millimeter wave, and sub-6GHz. Exactly which frequencies within those bands your devices will use varies from carrier to carrier, and country to country.
