5G is coming soon, but if you still have no idea what it is, or why it matters, then you're not alone. It isn't easy to gain a clear understanding of the subject — most explanations on the net end up being half vague marketing jargon and half complex technical details. That's why we're adding a new entry to our layman's guide to 5G in anticipation of the first 5G smartphones and networks in 2019.

Of course, Keegan Michael Key's recent verbal explainer on the subject covers a fair amount on the topic — "It's one better than 4G, and it's two better than 3G" — but in case you want a bit more detail, we'll attempt to set out what you can expect from this new era of wireless, in the clearest terms possible.
